ASTM D8353-20

Standard Guide for Determination of Individual Particle Strength of Low Surface Area Catalysts and Catalyst Carriers by Drop Test onto a Steel Plate

SIGNIFICANCE AND USE
5.1 This guide is intended to provide information concerning the ability of formed catalysts or catalyst carriers to resist particle size reduction during use. It can be used by itself or in conjunction with other methods to assess catalytic material integrity, such as Test Methods D4058 and D7084.  
5.2 There are no known restrictions on sample geometry, as spheres, pellets, and hollow cylinders are suitable for testing.  
5.3 This guide, as written, is suitable for use for catalytic materials from about 1/8 in. to about 3/4 in. It can also be used for larger parts, but this requires using a larger diameter pipe.  
5.4 This guide is suitable for specification acceptance, manufacturing control, and research and development processes.
SCOPE
1.1 The resistance to breakage of formed catalysts, catalyst carriers, or catalyst pieces is determined by dropping a quantity of sample through a 25 ft length of 1 in. internal diameter pipe onto a steel plate.  
1.2 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.  
1.3 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.

breakage) or fail (breakage) basis and is calculated as percent-
