This International Standard describes the principles and methods for the expression of results of per-formance tests on sizing equipment used in coal preparation, and includes methods for the evaluation of performance parameters. Performance test pro-cedures and size measurement techniques are rec-ommended.
This International Standard applies to all types of siz-ing equipment, categorized as follows:
a) screens;
b) classifiers;
c) others.
The procedure described in this International Standard applies to two-product separations. Performance as-sessment of multiproduct separations can be achieved by consideration of a series of two-product separations.
