19、ment used in coal preparation, and includes methods for the evaluation of performance parameters. Performance test procedures and size measurement techniques are recommended. This International Standard applies to all types of sizing equipment, categorized as follows: a) screens; b) classifiers; c)
20、others. The procedure described in this International Standard applies to two-product separations. Performance assessment of multiproduct separations can be achieved by consideration of a series of two-product separations. 2 Normative references The following standards contain provisions which, thro
