Significance and Use
5.1 This test method is to be used for measuring the mechanically tapped packing density of formed particles that will not break up during sampling, filling, or tapping of the measuring cylinder under test conditions.
1.1 This test method covers the determination of the mechanically tapped density of formed catalyst and catalyst carriers. For the purpose of this test method, catalyst particles are defined as extrudates, spheres, or formed pellets of 0.8 to 4.8-mm (1/32 to 3/16-in.) nominal diameter.
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 and health practices and determine the applicability of regulatory limitations prior to use.
