Significance and Use
5.1 This test method is intended to provide information on the ability of an extruded catalyst to retain physical integrity during use.
1.1 This test method covers and is suitable for determining the resistance of extruded catalysts and catalyst carriers to compressive force from the side.
1.2 This test method was developed using extruded catalyst and catalyst carriers from 1/16 to 1/8 in. in diameter (0.159 to 0.318 cm) and limited to pieces with a length to diameter ratio greater than or equal to 1:1. This test method may be applicable to other diameters.
1.3 This test method is suitable for the determination of mean crush strength per millimetre in the range of 0 to 15 lbf/mm (0 to 65 N/mm).
1.4 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.
1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
