Annex II

Section 3 of Annex III to Regulation (EC) No 2003/2003 is amended as follows:

1. 1..

   in Method 2, point 6.2 is replaced by the following:

   ‘6.2.

   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.’;

2. 2..

   in Method 3, point 4.3.5 is replaced by the following:

   ‘4.3.5.

   Dreschel bottle D acting as a trap for any excess of acid which may distil over.’;

3. 3..

   in Method 3, the first paragraph of point 5.2 is replaced by the following:

   ‘Place the sample for analysis in the reaction flask B. Add 100 ml of H₂SO₄ (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.’
