ASTM D4180-03(2008)
(Test Method)Standard Test Method for Vibratory Packing Density of Formed Catalyst Particles and Catalyst Carriers
Standard Test Method for Vibratory Packing Density of Formed Catalyst Particles and Catalyst Carriers
SIGNIFICANCE AND USE
This test method is to be used for measuring the vibratory packing density of formed particles that will not break up during sampling, filling, or vibrating of the measuring cylinder under test conditions.
SCOPE
1.1 This test method covers the determination of the vibratory packing density of formed catalyst and catalyst carriers. For the purpose of this test, catalyst particles are defined as extrudates, spheres, or formed pellets of 0.8 to 4.8-mm (1/32to 3/16-in.) nominal diameter.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
