Organization: ASTM
Publication Date: 10 September 1996
Status: active
Page Count: 3
ICS Code (Chemical reagents): 71.040.30
scope:

This test method covers the determination of the attrition and abrasion resistance of catalysts and catalyst carriers. It is applicable to tablets, extrudate, spheres, and irregularly shaped particles larger than about 116 in. (1.6 mm) and smaller than about 34 in. (19 mm). The materials used in developing the method exhibited losses on attrition less than 7 %; however, the method should be applicable to materials giving much higher attritions.

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.

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.

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.
