ASTM D4699-03(2008)
(Test Method)Standard Test Method for Vibratory Packing Density of Large Formed Catalyst and Catalyst Carrier Particles
Standard Test Method for Vibratory Packing Density of Large Formed Catalyst and Catalyst Carrier Particles
SIGNIFICANCE AND USE
This test method is used for measuring the vibratory packing density of formed particles used in fixed bed reactors, driers, and so forth.
SCOPE
1.1 This test method covers the determination of the vibratory packing density of formed catalyst and catalyst carrier particles that will not break up significantly under test conditions. For the purpose of this test, catalyst particles are defined as extrudates, spheres or formed pellets greater than 4.8 mm (3/16 in.).
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.
