1.1This test method covers the determination of the mechanically tapped packing density of fine catalyst and catalyst carrier particles smaller than 0.8 mm in diameter.
1.2The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3This 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.
1.4This 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.
