Scope

1.1 This test method covers determining the resistance of formed catalysts and catalyst carriers to compressive force and is applicable to regular catalyst shapes such as tablets and spheres. Extrudates, granular materials, and other irregular shapes are specifically excluded.

1.2 This test method determines the average crush strength in the range from 0 to 50 lbf (0 to 220 N). Some materials may have crush strengths above 50 lbf (220N); the test method is applicable to these materials, but the precision of the test is not known.

1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.4 This standard does not purport to address all of the safety concerns, 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.

Significance and Use

This test method is intended to provide information concerning the ability of a catalyst shape to retain physical integrity during use.
