ASTM D5757-11(2017) PDF

Scope: 1.1 This test method covers the determination of the relative attrition characteristics of FCC catalysts by means of air jet attrition. Other fine powder catalysts can be analyzed by this test method but the precision of this test method has been determined only for FCC catalysts. It is applicable to spherically or irregularly shaped particles which range in size between 10 and 180 µm, have skeletal densities between 2.4 and 3.0 g/cm3 (2400 and 3000 kg ⁄m3 ) (see IEEE/ASTM SI-10) and are insoluble in water. Particles less than 20 µm are considered fines. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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.
