Paragraph 4 SAMPLING
Procedure for samples with dry matter content ≥ 60%
Pass the laboratory sample through a sieve with nominal apertures of 10.00 mm (3.3). If necessary, lightly crush any lumps by means of a soft brush. Remove any lumps which cannot be crushed in this way and record the weight of the residue and the weight of the lumps. Take account of these lumps when recording the final results. Thoroughly mix the sieved sample and quarter down until a representative sample portion of about 50 g is obtained.
Procedure for samples with dry matter content < 60% which cannot be treated as per 4.1 due to the nature of the material
Empty the whole of the sample onto a clean dry surface and flatten to form a regular shape about 25 mm thick. Divide into four approximately equal portions and reject two opposite quarters. Take small portions from random places on all the exposed surfaces to give a sample portion of about 50 g.
