Regulation (EC) No 2003/2003 of the European Parliament and of the Council
of 13 October 2003
relating to fertilisers
(Text with EEA relevance)cross-notes
THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION,
Having regard to the Treaty establishing the European Community, and in particular Article 95 thereof,
Having regard to the proposal from the Commission(1),
Having regard to the Opinion of the European Economic and Social Committee(2),
Acting in accordance with the procedure laid down in Article 251 of the Treaty(3),
Whereas:
(1) Council Directive 76/116/EEC of 18 December 1975 on the approximation of the laws of the Member States relating to fertilisers(4), Council Directive 80/876/EEC of 15 July 1980 on the approximation of the laws of the Member States relating to straight ammonium nitrate fertilisers of high nitrogen content(5), Commission Directive 87/94/EEC of 8 December 1986 on the approximation of the laws of the Member States relating to procedures for the control of characteristics of, limits for and resistance to detonation of straight ammonium nitrate fertilisers of high nitrogen content(6), and Commission Directive 77/535/EEC of 22 June 1977 on the approximation of the laws of the Member States relating to methods of sampling and analysis for fertilisers(7), have been substantially amended several times. In accordance with the communication from the Commission to the European Parliament and the Council ‘Simpler legislation for the internal market’ (SLIM) and the Action Plan for the Single Market those Directives should be repealed and replaced by a single legal instrument, in the interests of clarity.
(2) The Community legislation on fertilisers is very technical in its content. A Regulation is therefore the most appropriate legal instrument, as it imposes directly on manufacturers precise requirements to be applied at the same time and in the same manner throughout the Community.
(3) In each Member State fertilisers must display certain technical characteristics laid down by mandatory provisions. These provisions, concerning more particularly the composition and definition types of fertilisers, the designations of these types, their identification and their packaging, differ from one Member State to another. By their disparity they hinder trade within the Community and should therefore be harmonised.
(4) Since the objective of the proposed action, namely to ensure the internal market in fertilisers, cannot be sufficiently achieved by the Member States if there are no common technical criteria and can therefore, by reason of the scale of the action, be better achieved at Community level, the Community may adopt measures in accordance with the principle of subsidiarity as set out in Article 5 of the Treaty. In accordance with the principle of proportionality, as set out in that Article, this Regulation does not go beyond what is necessary in order to achieve this objective.
(5) It is necessary to determine at Community level the designation, definition and composition of certain fertilisers (EC fertilisers).
(6) Community rules on the identification, traceability and labelling of EC fertilisers and on the closure of the packages should also be laid down.
(7) A procedure should be established at Community level to be followed in cases where a Member State deems it necessary to restrict the placing on the market of EC fertilisers.
(8) The production of fertilisers is subject to varying degrees of fluctuation due to manufacturing techniques or basic materials. Sampling and analytical procedures may also contain variations. It is therefore necessary to authorise tolerances on the declared nutrient contents. In the interest of the agricultural user, it is advisable to keep these tolerances within narrow limits.
(9) Official controls on the compliance of EC fertilisers with requirements of this Regulation concerning quality and composition should be carried out by laboratories that are approved by the Member States and notified to the Commission.
(10) Ammonium nitrate is the essential ingredient of a variety of products, some of which are intended for use as fertilisers and others as explosives. It is necessary, having regard to the particular nature of ammonium nitrate fertilisers of high nitrogen content and to the consequent requirements regarding public safety, health and protection of workers, to lay down additional Community rules for EC fertilisers of this type.
(11) Certain of those products could be hazardous and could in certain instances be used for purposes other than those for which they were intended. This could well endanger the security of persons and property. Manufacturers should therefore be obliged to take appropriate steps to avoid such use, and in particular to ensure the traceability of such fertilisers.
(12) In the interest of public safety, it is particularly important to determine at Community level the characteristics and properties distinguishing ammonium nitrate EC fertilisers of high nitrogen content from varieties of ammonium nitrate used in the manufacture of products used as explosives.
(13) Ammonium nitrate EC fertilisers of high nitrogen content should conform to certain characteristics to ensure that they are harmless. Manufacturers should ensure that all high nitrogen content ammonium nitrate fertilisers have passed a test of resistance to detonation before those fertilisers are placed on the market.
(14) It is necessary to establish rules on the methods of the closed thermal cycles even if these methods may not necessarily simulate all conditions arising during transport and storage.
(15) Fertilisers can be contaminated by substances that can potentially pose a risk to human and animal health and the environment. Further to the opinion of the Scientific Committee on Toxicity, Ecotoxicity and the Environment (SCTEE), the Commission intends to address the issue of unintentional cadmium content in mineral fertilisers and will, where appropriate, draw up a proposal for a Regulation, which it intends to present to the European Parliament and the Council. Where appropriate, a similar review will be undertaken for other contaminants.
(16) It is appropriate to establish a procedure, to be observed by any manufacturer or its representative that wishes to include a new type of fertiliser in Annex I in order to use the marking ‘EC fertiliser’.
(17) The measures necessary for the implementation of this Regulation should be adopted in accordance with Council Decision 1999/468/EC of 28 June 1999 laying down the procedures for the exercise of implementing powers conferred on the Commission(8).
(18) Member States should lay down penalties in respect of infringements of the provisions of this Regulation. They may provide that a manufacturer which infringes Article 27 can be fined an amount equivalent to ten times the market value of the shipment that fails to comply.
(19) Directives 76/116/EEC, 77/535/EEC, 80/876/EEC and 87/94/EEC should be repealed,
HAVE ADOPTED THIS REGULATION:
TITLE I GENERAL PROVISIONS

Article 6 Compulsory statements
1.[F12 Nothing in this Regulation prevents the appropriate authority, in order to satisfy the requirements of Article 9, from using any power the appropriate authority has toF12] prescribe that the indication of the nitrogen, phosphorus and potassium contents of fertilisers placed on [F13the marketF13] is to be expressed in the following way:
(a)nitrogen solely in the elemental form (N); and either
(b)phosphorus and potassium solely in the elemental form (P, K); or
(c)phosphorus and potassium solely in the oxide form (P2O5, K2O); or
(d)phosphorus and potassium in both elemental and oxide forms simultaneously.
Where the option is chosen to prescribe that the phosphorus and potassium contents be expressed in the form of elements, all references in the Annexes to the oxide form shall be read as being in elemental form and the numerical values shall be converted using the following factors:
(a)phosphorus (P) = phosphorus pentoxide (P2O5) × 0,436;
(b)potassium (K) = potassium oxide (K2O) × 0,830.
2.[F14 Nothing in this Regulation prevents the appropriate authority from using any power the appropriate authority has toF14] prescribe that the calcium, magnesium, sodium and sulphur contents of secondary nutrient fertilisers and, where the conditions of Article 17 are fulfilled, of primary nutrient fertilisers placed on [F15the marketF15] are to be expressed:
(a)in the oxide form (CaO, MgO, Na2O, SO3); or
(b)in the elemental form (Ca, Mg, Na, S); or
(c)in both of these forms.
To convert the calcium oxide, magnesium oxide, sodium oxide and sulphur trioxide contents into calcium, magnesium, sodium and sulphur contents, the following factors shall be used:
(a)calcium (Ca) = calcium oxide (CaO) × 0,715;
(b)magnesium (Mg) = magnesium oxide (MgO) × 0,603;
(c)sodium (Na) = sodium oxide (Na2O) × 0,742;
(d)sulphur (S) = sulphur trioxide (SO3) × 0,400.
For the calculated oxide or elemental content, the figure declared shall be rounded to the nearest decimal place.
3. [F16 The appropriate authority F16] shall not prevent the placing on the market of an ‘ [F1 UK fertiliser F1] ’ labelled in both of the forms mentioned in paragraphs 1 and 2.
4.The content of one or more of the micro-nutrients boron, cobalt, copper, iron, manganese, molybdenum, or zinc in the [F17UK fertilisersF17] belonging to the types of fertilisers listed in sections A, B, C and D of Annex I shall be declared where the following conditions are fulfilled:
(a)the micro-nutrients are added at least in the minimum quantities specified in section E.2.2 and E.2.3 of Annex I;
(b)the [F1UK fertiliserF1] continues to satisfy the requirements of sections A, B, C and D of Annex I.
5.Where the micro-nutrients are the normal ingredients of the raw materials intended to supply primary (N, P, K) and secondary (Ca, Mg, Na, S) nutrients, they may be declared, provided that these micro-nutrients are present at least in the minimum quantities specified in sections E.2.2 and E.2.3 of Annex I.
6.The micro-nutrient content shall be declared in the following manner:
(a)for fertilisers belonging to the types of fertilisers listed in section E.1 of Annex I, in accordance with the requirements set out in column 6 of that section;
(b)for mixtures of fertilisers referred to in (a) containing at least two different micro-nutrients and meeting the requirements of section E.2.1 of Annex I and for fertilisers belonging to the types of fertilisers listed in sections A, B, C and D of Annex I, by indicating:
the total content, expressed as a percentage of the fertiliser by mass,
the water-soluble content, expressed as a percentage of the fertiliser by mass, where the soluble content is at least half of the total content.
Where a micro-nutrient is totally water-soluble, only the water-soluble content shall be declared.
Where a micro-nutrient is chemically linked with an organic molecule, the content of the micro-nutrient present in the fertiliser shall be declared immediately following the water-soluble content as a percentage by mass of the product, followed by one of the terms ‘chelated by’, or ‘complexed by’, with the name of the organic molecule as set out in section E.3 of Annex I. The name of the organic molecule may be replaced by its initials.

2.Description of the test of resistance to detonation concerning ammonium nitrate fertilisers of high nitrogen content
The test must be carried out on a representative sample of fertiliser. Before being tested for resistance to detonation, the whole mass of the sample is to be thermally cycled five times complying with the provisions of part 3 in section 3. of this Annex.
The fertiliser must be subjected to the test of resistance to detonation in a horizontal steel tube under the following conditions:
seamless steel tube,
Tube length: 1 000 mm at least,
Nominal external diameter: 114 mm at least,
Nominal wall thickness: 5 mm at least,
Booster: the type and mass of the booster chosen should be such as to maximise the detonation pressure applied to the sample in order to determine its susceptibility to the transmission of detonation,
Test temperature: 15-25 °C,
Witness lead cylinders for detecting detonation: 50 mm diameter and 100 mm high
placed at 150 mm intervals and supporting the tube horizontally. The test is to be carried out twice. The test is deemed conclusive if in both tests one or more of the supporting lead cylinders is crushed by less than 5 %.
3.Methods of checking compliance with the limits specified in Annexes III-1 and III-2
Method 1Methods for the application of thermal cycles
1.Scope and field of application
This document defines the procedures for the application of thermal cycles prior to the execution of the oil retention test for straight ammonium nitrate fertilisers of high nitrogen content and of the test on the resistance to detonation for both, straight and compound ammonium nitrate fertiliser of high nitrogen content.
The methods of the closed thermal cycles as described in this section are regarded as simulating sufficiently the conditions to be taken into account within the scope of application of title II, chapter IV, however, these methods may not necessarily simulate all conditions arising during transport and storage;
2.Thermal cycles referred to in Annex III-1
2.1.Field of application
This procedure is for thermal cycling prior to determining the oil retention of the fertiliser.
2.2.Principle and definition
In an Erlenmeyer flask, heat the sample from ambient temperature to 50 °C and maintain at this temperature for a period of two hours (phase at 50 °C). Thereupon cool the sample until a temperature of 25 °C is achieved and maintain at that temperature for two hours (phase at 25 °C). The combination of the successive phases at 50 °C and 25 °C forms one thermal cycle. After being subjected to two thermal cycles, the test sample is held at a temperature of 20 ± 3 °C for the determination of the oil retention value.
2.3.Apparatus
Normal laboratory apparatus, in particular:
water baths thermostated at 25 (± 1) and 50 (± 1) °C respectively,
Erlenmeyer flasks with an individual capacity of 150 ml.
2.4.Procedure
Put each test sample of 70 (± 5) grams into an Erlenmeyer flask which is then sealed with a stopper.
Move each flask every two hours from the 50 °C bath to the 25 °C bath and vice versa.
Maintain the water in each bath at constant temperature and keep in motion by rapid stirring to ensure the water level comes above the level of the sample. Protect the stopper from condensation by a foam rubber cap.
3.Thermal cycles to be used for Annex III-2
3.1.Field of application
This procedure is for thermal cycling prior to the execution of the detonability test.
3.2.Principle and definition
In a watertight box heat the sample from ambient temperature to 50 °C and maintain at this temperature for a period of one hour (phase at 50 °C). Thereupon cool the sample until a temperature of 25 °C is achieved and maintain at that temperature for one hour (phase at 25 °C). The combination of the successive phases at 50 °C and 25 °C forms one thermal cycle. After being subjected to the required number of thermal cycles, the test sample is held at a temperature of 20 ± 3 °C pending the execution of the detonability test.
3.3.Apparatus
A water bath, thermostated in a temperature range of 20 to 51 °C with a minimum heating and cooling rate of 10 °C/h, or two water baths, one thermostated at a temperature of 20 °C, the other at 51 °C. The water in the bath(s) is continuously stirred; the volume of the bath should be large enough to guarantee ample circulation of the water.
A stainless steel box, watertight all around and provided with a thermocouple in the centre. The outside width of the box is 45 (± 2) mm and the wall thickness is 1,5 mm (see Figure 1). The height and length of the box can be chosen to suit the dimensions of the water bath, e.g. length 600 mm, height 400 mm.
3.4.Procedure
Place a quantity of fertilisers sufficient for a single detonation into the box and close the cover. Place the box in the water bath. Heat the water to 51 °C and measure the temperature in the centre of the fertiliser. One hour after the temperature at the centre has reached 50 °C cool the water. One hour after the temperature at the centre has reached 25 °C heat the water to start the second cycle. In the case of two water baths, transfer the box to the other bath after each heating/cooling period.

Method 2Determination of oil retention
1.Scope and field of application
This document defines the procedure for the determination of oil retention of straight ammonium nitrate fertilisers of high nitrogen content.
The method is applicable to both prilled and granular fertilisers which do not contain oil-soluble materials.
2.Definition
Oil retention of a fertiliser: the quantity of oil retained by the fertiliser determined under the operating conditions specified, and expressed as a percentage by mass.
3.Principle
Total immersion of the test portion in gas oil for a specified period, followed by the draining away of surplus oil under specified conditions. Measurement of the increase in mass of the test portion.
4.Reagent
Gas oil
:
5 mPas at 40 °C
:
0,8 to 0,85 g/ml at 20 °C
:
≤ 1,0 % (m/m)
:
≤ 0,1 % (m/m)
5.Apparatus
Ordinary laboratory apparatus, and:
Balance, capable of weighing to the nearest 0,01 gram.
Beakers, of capacity 500 ml.
Funnel, of plastic materials, preferably with a cylindrical wall at the upper end, diameter approximately 200 mm.
Test sieve, aperture 0,5 mm, fitting into the funnel (5.3).
Note: The size of the funnel and sieve is such as to ensure that only a few granules lie one above another and the oil is able to drain easily.
Filter paper, rapid filtering grade, creped, soft, mass 150 g/m2.
Absorbent tissue (laboratory grade).
6.Procedure
6.1.Two individual determinations are carried out in quick succession on separate portions of the same test sample.
[F796.2.Remove particles smaller than 0,5 mm using the test sieve (5.4). Weigh to the nearest 0,01 gram approximately 50 grams of the sample into the beaker (5.2). Add sufficient gas oil (section 4) to cover the prills or granules completely and stir carefully to ensure that the surfaces of all the prills or granules are fully wetted. Cover the beaker with a watch glass and leave to stand for one hour at 25 (± 2) °C.F79]
6.3.Filter the entire contents of the beaker through the funnel (5.3) containing the test sieve (5.4). Allow the portion retained by the sieve to remain there for one hour so that most of the excess oil can drain away.
6.4.Lay two sheets of filter paper (5.5) (about 500 × 500 mm) on top of each other on a smooth surface; fold the four edges of both filter papers upwards to a width of about 40 mm to prevent the prills from rolling away. Place two layers of absorbent tissue (5.6) in the centre of the filter papers. Pour the entire contents of the sieve (5.4) over the absorbent tissues and spread the prills evenly with a soft, flat brush. After two minutes lift one side of the tissues to transfer the prills to the filter papers beneath and spread them evenly over these with the brush. Lay another sheet of filter paper, similarly with its edges turned upward, on the sample and roll the prills between the filter papers with circular movements while exerting a little pressure. Pause after every eight circular movements to lift the opposite edges of the filter papers and return to the centre the prills that have rolled to the periphery. Keep to the following procedure: make four complete circular movements, first clockwise and then anticlockwise. Then roll the prills back to the centre as described above. This procedure to be carried out three times (24 circular movements, edges lifted twice). Carefully insert a new sheet of filter paper between the bottom sheet and the one above it and allow the prills to roll onto the new sheet by lifting the edges of the upper sheet. Cover the prills with a new sheet of filter paper and repeat the same procedure as described above. Immediately after rolling, pour the prills into a tared dish and reweigh to the nearest 0,01 gram to determine the mass of the quantity of gas oil retained.
6.5.Repeating the rolling procedure and reweighing
If the quantity of gas oil retained in the portion is found to be greater than 2 grams, place the portion on a fresh set of filter papers and repeat the rolling procedure, lifting the corners in accordance with section 6.4 (two times eight circular movements, lifting once). Then reweigh the portion.
7.Expression of the results
7.1.Method of calculation and formula
The oil retention, from each determination (6.1) expressed as a percentage by mass of the sieved test portion, is given by the equation:
where:
m1 is the mass, in grams, of the sieved test portion (6.2),
m2 is the mass, in grams, of the test portion according to section 6.4 or 6.5 respectively as the result of the last weighing.
Take as the result the arithmetic mean of the two individual determinations.
Method 3Determination of the combustible ingredients
1.Scope and field of application
This document defines the procedure for the determination of the combustible content of straight ammonium nitrate fertilisers of high nitrogen content.
2.Principle
The carbon dioxide produced by inorganic fillers is removed in advance with an acid. The organic compounds are oxidised by means of a chromic acid/sulphuric acid mixture. Carbon dioxide formed is absorbed in a barium hydroxide solution. The precipitate is dissolved in a solution of hydrochloric acid and measured by back-titration with sodium hydroxide solution.
3.Reagents
3.1.Analytical-grade chromium (VI) trioxide Cr2O3;
3.2.Sulphuric acid, 60 % by volume: pour 360 ml of water into a one-litre beaker and carefully add 640 ml of sulphuric acid (density at 20 °C = 1.83 g/ml).
3.3.Silver nitrate: 0,1 mol/l solution.
3.4.Barium hydroxide
Weigh out 15 grams of barium hydroxide [Ba(OH)2. 8H2O], and dissolve completely in hot water. Allow to cool and transfer to a one-litre flask. Fill up to the mark and mix. Filter through a pleated filter paper.
3.5.Hydrochloric acid: 0,1 mol/l standard solution.
3.6.Sodium hydroxide: 0,1 mol/l standard solution.
3.7.Bromophenol blue: solution of 0,4 grams per litre in water.
3.8.Phenolphthalein: solution of 2 grams per litre in 60 % by volume ethanol.
3.9.Soda lime: particle dimensions, about 1,0 to 1,5 mm.
3.10.Demineralised water, freshly boiled to remove carbon dioxide.
4.Apparatus
4.1.Standard laboratory equipment, in particular:
filter crucible with a plate of sintered glass and a capacity of 15 ml; plate diameter: 20 mm; total height: 50 mm; porosity 4 (pore diameter from 5 to 15 μm),
600-ml beaker.
4.2.Compressed nitrogen supply.
4.3.Apparatus made up of the following parts and assembled, if possible, by means of spherical ground joints (see Figure 2).

500-ml reaction flask B with side arm and a round bottom.
Vigreux fractionating column about 150 mm long (C').
Double-surface condenser C, 200 mm long.
[F79 Dreschel bottle D acting as a trap for any excess of acid which may distil over.F79]
Ice bath E to cool the Drechsel bottle.
Two absorption vessels F1 and F2, 32 to 35 mm in diameter, the gas distributor of which comprises a 10 mm disc of low-porosity sintered glass.
Suction pump and suction regulating device G comprising a T-shaped glass piece inserted into the circuit, the free arm of which is connected to the fine capillary tube by a short rubber tube fitted with a screw clamp.
Caution: The use of boiling chromic acid solution in an apparatus under reduced pressure is a hazardous operation and requires appropriate precautions.
5.Procedure
5.1.Sample for analysis
Weigh approximately 10 grams of ammonium nitrate to the nearest 0,001 grams.
5.2.Removal of carbonates
[F79 Place the sample for analysis in the reaction flask B. Add 100 ml of H 2 SO 4 (3.2). The prills or granules dissolve in about 10 minutes at ambient temperature. Assemble the apparatus as indicated in the diagram: connect one end of the absorption tube (A) to the nitrogen source (4.2) via a non-return flow device containing a pressure of 667 to 800 Pa and the other end to the feed tube which enters the reaction flask. Place the Vigreux fractionating column (C′) and the condenser (C) with cooling water supply in position. Adjust the nitrogen to provide a moderate flow through the solution, bring the solution to boiling point and heat for two minutes. At the end of this time there should be no more effervescence. If effervescence is seen, continue heating for 30 minutes. Allow solution to cool for at least 20 minutes with the nitrogen flowing through it.F79]
Complete assembly of the apparatus as indicated in the diagram by connecting the condenser tube to the Drechsel bottle (D) and the bottle to the absorption vessels F1 and F2. The nitrogen must continue to pass through the solution during the assembly operation. Rapidly introduce 50 ml of barium hydroxide solution (3.4) into each of the absorption vessels (F1 and F2).
Bubble a stream of nitrogen through for about 10 minutes. The solution must remain clear in the absorbers. If this does not happen, the carbonate removal process must be repeated.
5.3.Oxidation and absorption
After withdrawing the nitrogen feed tube, rapidly introduce 20 grams of chromium trioxide (3.1) and 6 ml of silver nitrate solution (3.3) via the side arm of the reaction flask (B). Connect the apparatus to the suction pump and adjust the nitrogen flow so that a steady stream of gas bubbles passes through the sintered-glass absorbers F1 and F2.
Heat the reaction flask (B) until the liquid boils and keep it boiling for one and a half hours(9). It may be necessary to adjust the suction-regulating valve (G) to control the nitrogen flow since it is possible that the barium carbonate precipitated during the test may block the sintered-glass discs. The operation is satisfactory when the barium hydroxide solution in the absorber F2 remains clear. Otherwise repeat the test. Stop heating and dismantle the apparatus. Wash each of the distributors (3.10) both inside and outside to remove barium hydroxide and collect the washings in the corresponding absorber. Place the distributors one after the other in a 600-ml beaker which will subsequently be used for the determination.
Rapidly filter under vacuum firstly the contents of absorber F2 and then of absorber F1 using the sintered-glass crucible. Collect the precipitate by rinsing the absorbers with water (3.10) and wash the crucible with 50 ml of the same water. Place the crucible in the 600-ml beaker and add about 100 ml of boiled water (3.10). Introduce 50 ml of boiled water into each of the absorbers and pass nitrogen through the distributors for five minutes. Combine the water with that from the beaker. Repeat the operation once to ensure that the distributors are rinsed thoroughly.
5.4.Measurement of the carbonates originating from organic material
Add five drops of phenolphthalein (3.8) to the contents of the beaker. The solution becomes red in colour. Add hydrochloric acid (3.5) drop by drop until the pink colour just disappears. Stir the solution well in the crucible to check that the pink colour does not reappear. Add five drops of bromphenol blue (3.7) and titrate with hydrochloric acid (3.5) until the solution turns yellow. Add a further 10 ml of hydrochloric acid.
Heat the solution to boiling point and continue boiling for a maximum of one minute. Check carefully that no precipitate remains in the liquid.
Allow to cool and back titrate with the sodium hydroxide solution (3.6).
6.Blank test
Carry out a blank test following the same procedure and using the same quantities of all reagents.
7.Expression of the results
The content of combustible ingredients (C), expressed as carbon, as a percentage by mass of the sample, is given by the formula:
where:
=
the mass in grams of the test portion,
=
the total volume in ml of 0,1 mol/l hydrochloric acid added after the change in colour of the phenolphthalein,
=
the volume in ml of the 0,1 mol/l sodium hydroxide solution used for back titration.

4.3.Magnetic stirrer, with a Teflon-coated rod.
4.4.Microburette with fine-pointed tip, graduated in 0,01 ml divisions.
5.Procedure
5.1.Standardisation of the silver nitrate solution
Take 5,00 ml and 10,00 ml of the standard reference potassium chloride solution (3.6) and place in two low-form beakers of convenient capacity (for example 250 ml). Carry out the following titration of the contents of each beaker.
Add 5 ml of the nitric acid solution (3.2), 120 ml of the acetone (3.1) and sufficient water to bring the total volume to about 150 ml. Place the rod of the magnetic stirrer (4.3) in the beaker and set the stirrer in motion. Immerse the silver electrode (4.1) and the free end of the bridge (4.2) in the solution. Connect the electrodes to the potentiometer (4.1) and, after verifying the zero of the apparatus, note the value of the starting potential.
Titrate, using the microburette (4.4), adding initially 4 or 9 ml respectively of the silver nitrate solution corresponding to the standard reference potassium chloride solution used. Continue the addition in 0,1 ml portions for the 0,004 mol/l solutions and in 0,05 ml portions for the 0,1 mol/l solutions. After each addition, await the stabilisation of the potential.
Record the volumes added and the corresponding values of the potential in the first two columns of a table.
In a third column of the table, record the successive increments (Δ1E) of the potential E. In a fourth column, record the differences (Δ2E) positive or negative, between the potential increments (Δ1E). The end of the titration corresponds to the addition of the 0,1 or 0,05 ml portion (V1) of the silver nitrate solution which gives the maximum value of Δ1E.
In order to calculate the exact volume (Veq) of the silver nitrate solution corresponding to the end of the reaction, use the formula:
where:
V0 is the total volume, in ml, of the silver nitrate solution immediately lower than the volume which gives the maximum increment of Δ1E,
V1 is the volume, in ml, of the last portion of the silver nitrate solution added (0,1 or 0,05 ml),
b is the last positive value of Δ2E,
B is the sum of the absolute values of the last positive values of Δ2E and the first negative value of Δ2E (see example in Table 1).
5.2.Blank test
Carry out a blank test and take account thereof when calculating the final result.
The result V4 of the blank test on the reagents is given, in ml, by the formula:
where:
V2 is the value, in ml, of the exact volume (Veq) of the silver nitrate solution corresponding to the titration of 10 ml of the potassium chloride standard reference solution used,
V3 is the value, in ml, of the exact volume (Veq) of the silver nitrate solution corresponding to the titration of 5 ml of the potassium chloride standard reference solution used.
5.3.Check test
The blank test can at the same time serve as a check that the apparatus is functioning satisfactorily and that the test procedure is being implemented correctly.
5.4.Determination
Take a portion of sample in the range 10 to 20 grams and weigh to the nearest 0,01 gram. Transfer quantitatively to a 250-ml beaker. Add 20 ml of water, 5 ml of nitric acid solution (3.2), 120 ml of acetone (3.1) and sufficient water to bring the total volume to about 150 ml.
Place the rod of the magnetic stirrer (4.3) in the beaker, place the beaker on the stirrer and set the stirrer in motion. Immerse the silver electrode (4.1) and the free end of the bridge (4.2) in the solution, connect the electrodes to the potentiometer (4.1) and, after having verified the zero of the apparatus, note the value of the starting potential.
Titrate with the silver nitrate solution, by additions from the microburette (4.4) in increments of 0,1 ml. After each addition, await the stabilisation of the potential.
Continue the titration as specified in 5.1, starting from the fourth paragraph: ‘Record the volumes added and the corresponding values of the potential in the first two columns of a table …’.
6.Expression of the results
Express the result of the analysis as the percentage of chlorine contained in the sample as received for analysis. Calculate the percentage of chlorine (Cl) content from the formula:
where:
T is the concentration of silver nitrate solution used, in mol/l
V4 is the result, in ml, of the blank test (5.2),
V5 is the value, in ml, of Veq corresponding to the determination (5.4),
m is the mass, in grams, of the test portion.

4.4.Procedure
4.4.1.Preparation of booster charge for insertion into steel tube
There are two methods of initiation of the explosive in the booster charge, depending on the availability of equipment.
4.4.1.1.Seven-point simultaneous initiation
The booster charge prepared for use is shown in Figure 1.
4.4.1.1.1.Drill holes in the wooden disc (4.3.10) parallel to the axis of the disc through the centre and through six points symmetrically distributed around a concentric circle 55 mm in diameter. The diameter of the holes must be 6 to 7 mm (see Section A-B in Figure 1), depending on the diameter of the detonating cord used (4.3.2).
4.4.1.1.2.Cut seven lengths of flexible detonating cord (4.3.2) each 400 mm long, avoiding any loss of explosive at each end by making a clean cut and immediately sealing the end with adhesive. Push each of the seven lengths through the seven holes in the wooden disc (4.3.10) until their ends project a few centimetres on the other side of the disc. Then insert a small dressmaking pin (4.3.12) transversally into the textile sleeve of each length of cord 5 to 6 mm from the end and apply adhesive around the outside of the lengths of cord in a band 2 cm wide adjacent to the pin. Finally, pull the long piece of each cord to bring the pin into contact with the wooden disc.
4.4.1.1.3.Shape the plastic explosive (4.3.1) to form a cylinder 92 to 96 mm in diameter, depending on the diameter of the cylinder (4.3.8). Stand this cylinder upright on a level surface and insert the shaped explosive. Then insert the wooden disc(12) carrying the seven lengths of detonating cord into the top of the cylinder and press it down onto the explosive. Adjust the height of the cylinder (64 to 67 mm) so that its top edge does not extend beyond the level of the wood. Finally, fix the cylinder to the wooden disc for instance with staples or small nails, around its entire circumference.
4.4.1.1.4.Group the free ends of the seven lengths of detonating cord around the circumference of the wooden rod (4.3.11) so that their ends are all level in a plane perpendicular to the rod. Secure them in a bundle around the rod by means of adhesive tape(13).
4.4.1.2.Central initiation by a compressed pellet
The booster charge prepared for use is shown in Figure 2.
4.4.1.2.1.Preparing a compressed pellet
Taking the necessary safety precautions, place 10 grams of a secondary explosive (4.3.3) in a mould with an inside diameter of 19 to 21 mm and compress to the correct shape and density.
(The ratio of diameter: height should be roughly 1:1).
In the centre of the bottom of the mould there is a peg, 12 mm in height and 7,0 to 7,3 mm in diameter (depending on the diameter of the detonator used), which forms a cylindrical recess in the compressed cartridge for subsequent insertion of the detonator.
4.4.1.2.2.Preparing the booster charge
Place the explosive (4.3.1) into the cylinder (4.3.8) standing upright on a level surface, then press it down with a wooden die to give the explosive a cylindrical shape with a central recess. Insert the compressed pellet into this recess. Cover the cylindrically shaped explosive containing the compressed pellet with a wooden disc (4.3.10) having a central hole 7,0 to 7,3 mm in diameter for insertion of a detonator. Fix the wooden disc and the cylinder together with a cross of adhesive tape. Ensure that the hole drilled in the disc and the recess in the compressed pellet are coaxial by inserting the wooden rod (4.3.11).
4.4.2.Preparing steel tubes for the detonation tests
At one end of the steel tube (4.3.4), drill two diametrically opposed holes 4 mm in diameter perpendicularly through the side wall at a distance of 4 mm from the edge.
Butt weld the bottom plate (4.3.5) to the opposite end of the tube, completely filling the right angle between the bottom place and the wall of the tube with weld metal around the entire circumference of the tube.
4.4.3.Filling and charging the steel tube
See Figures 1 and 2.
4.4.3.1.The test sample, the steel tube and the booster charge must be conditioned to temperatures of 20 (± 5) °C. 16 to 18 kg of the test sample are needed for two detonation tests.
4.4.3.2.Place the tube upright with its square bottom place resting on a firm, flat surface, preferably concrete. Fill the tube to about one-third of its height with the test sample and drop it 10 cm vertically onto the floor five times to compact the prills or granules as densely as possible in the tube. To accelerate compaction, vibrate the tube by striking the side wall with a 750 to 1 000-gram hammer between drops for a total of 10 times.
Repeat this charging method with another portion of the test sample. Finally, a further addition shall be made such that, after compaction by raising and dropping the tube 10 times and a total of 20 intermittent hammer blows, the charge fills the tube to a distance of 70 mm from its orifice.
The filling height of the sample must be adjusted in the steel tube so that the booster charge (4.4.1.1 or 4.4.1.2) to be inserted later will be in close contact with the sample over its entire surface.
4.4.3.3.Insert the booster charge into the tube so that it is in contact with the sample; the top surface of the wooden disc must be 6 mm below the end of the tube. Ensure essential close contact between explosive and test sample by adding or removing small quantities of sample. As shown in Figures 1 and 2, split pins should be inserted through the holes near the open end of the tube and their legs opened flat against the tube.
4.4.4.Positioning of the steel tube and lead cylinders (see figure 3)
4.4.4.1.Number the bases of the lead cylinders (4.3.6) 1 to 6. Make six marks 150 mm apart on the centre line of a steel block (4.3.7) lying on a horizontal base, with the first mark at least 75 mm from the edge of the block. Place a lead cylinder upright on each of these marks, with the base of each cylinder centred on its mark.
4.4.4.2.Lay the steel tube prepared according to 4.4.3 horizontally on the lead cylinders so that the axis of the tube is parallel to the centre line of the steel block and the welded end of the tube extends 50 mm beyond lead cylinder No 6. To prevent the tube from rolling, insert small wooden wedges between the tops of the lead cylinders and the tube wall (one on each side) or place a cross of wood between the tube and the steel block.
Note: Make sure that the tube is in contact with all six lead cylinders; a slight curvature of the tube surface can be compensated for by rotating the tube about its longitudinal axis; if any of the lead cylinders is too tall, tap the cylinder in question carefully with a hammer until it is the required height.
4.4.5.Preparation for detonation
4.4.5.1.Set up the apparatus according to the 4.4.4 in a bunker or suitably prepared underground site (e.g. mine or tunnel). Ensure that the temperature of the steel tube is kept at 20 (± 5) °C before detonation.
Note: Should such firing sites not be available, the work can, if necessary, be done in a concrete-lined pit covered over with wooden beams. Detonation can cause steel fragments to be projected with high kinetic energy, therefore, firing must be carried out at a suitable distance from dwellings or thoroughfares.
4.4.5.2.If the booster charge with seven-point initiation is used, ensure that the detonation cords are stretched out as described in the footnote to 4.4.1.1.4 and arranged as horizontally as possible.
4.4.5.3.Finally, remove the wooden rod and replace with the detonator. Do not carry out firing until the danger zone has been evacuated and the test personnel have taken cover.
4.4.5.4.Detonate the explosive.
4.4.6.Allow sufficient time for the fumes (gaseous and sometimes toxic decomposition products such as nitrous gases) to disperse, then collect the lead cylinders and measure their heights with a Vernier caliper
Record for each of the marked lead cylinders, the degree of crushing expressed as a percentage of the original height of 100 mm. If the cylinders are crushed obliquely, record the highest and the lowest values and calculate the average.
4.4.7.A probe for continuous measurement of the detonation velocity can be used; the probe should be inserted longitudinally to the axis of the tube or along its side wall
4.4.8.Two detonation tests per sample are to be carried out
4.5.Test report
Values for the following parameters are to be given in the test report for each of the detonation tests:
the values actually measures for the outside diameter of the steel tube and for the wall thickness,
the Brinell hardness of the steel tube,
the temperature of the tube and the sample shortly before firing,
the packing density (kg/m3) of the sample in the steel tube,
the height of each lead cylinder after firing, specifying the corresponding cylinder number,
method of initiation employed for the booster charge.
4.5.1.Evaluation of test results
If, in each firing, the crushing of at least one lead cylinder is less than 5 %, the test shall be considered conclusive and the sample in conformity with the requirements of Annex III.2.

8.Sampling record
A record must be kept of each sampling, permitting each sampled portion to be identified unambiguously.
9.Destination of samples
For each sample portion at least one final sample shall be sent as quickly as possible to an authorised analytical laboratory or to the test institution, together with the information necessary for the analysis or the test.
B.METHODS FOR THE ANALYSIS OF FERTILISERS
(See table of contents p. 2.)
General observations
Laboratory equipment
In the descriptions of the methods, general laboratory equipment has not been precisely defined, except that the sizes of flasks and pipettes are given. In all cases laboratory apparatus must be well cleaned, particularly when small quantities of elements are to be determined.
Control tests
Before analysis it is necessary to ensure that all apparatus functions well and that the analytical technique is carried out correctly, using where appropriate chemical compounds of known composition (e.g. ammonium sulphate, mono potassium phosphate, etc.). Nevertheless, the results from analysed fertilisers can indicate wrong chemical composition if the analytical technique is not rigorously followed. On the other hand, a certain number of determinations are empirical and are relative to products of complex chemical composition. It is recommended that where available, laboratories should make use of standard reference fertilisers of well defined composition.
General provisions relating to methods of analysing fertilisers
1.Reagents
Unless otherwise specified in the method of analysis, all of the reagents must be analysis-pur (a.p.). Where micro-nutrients are to be analysed the purity of the reagents must be checked by means of a blank test. Depending upon the result obtained, it might be necessary to conduct a further purification.
2.Water
Where dissolution, dilution, rinsing or washing operations referred to in the methods of analysis do not specify the nature of solvents or diluents the use of water is implied. Normally, the water will have to be demineralised or distilled. In these specific instances, as mentioned in the method of analysis, that water will have to be subjected to specific purification processes.
3.Laboratory equipment
In view of the equipment normally used in inspection laboratories, the apparatus described in the methods of analysis is restricted to special instruments and apparatus or to such demanded by any specific requirements. This equipment must be perfectly clean, above all where small quantities are to be determined. The laboratory will have to ensure the accuracy of any graduated glassware used by referring to appropriate metrological standards.
