1.1This test method describes a procedure for obtaining a relative measure of the resistance to degradation of coke by impact and abrasion.

1.2Standard Procedure-This procedure uses a coke sample sized to −75 mm [−3 in.] and + 50 mm [ + 2 in.].

1.3Alternative Procedure-This procedure using coke sized 50 % of 63 by 50 mm [2¹/₂by 2 in.] and 50 % of 50 by 37.5 mm [2 by 1¹/₂in.].

1.4The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.5This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
