This International Standard describes the general techniques of taking and preparing samples with a view to the assessment of a solid Chemical product lot, for use in conjunction with a previously established sampling plan (as described, for example, in ISO 6663 or ISO 6064). This International Standard is applicable to solid Chemical products, in particulate form, ranging from powders to coarse lumps with a maximum size of 100 mm, and consigned in containers (of, for example, 25, 50 or 100 kg) or in bulk. Massive pieces and solids in a plastic are not dealt with in this International Standard. NOTE - This International Standard should be used in conjunction with the vocabulary, given in ISO 6206.
