ASTM International Standard Test Method for Bulk Density of Granular Refractory Materials ASTM C357-07(2022)

1.1 This test method covers a procedure for determining the bulk density of granular refractory materials, commercial products which usually have particles that are retained on a 0.265 in. (6.7 mm) or coarser sieve. Note 1: This test method is not suitable for materials that hydrate in boiling water. 1.2 Units-The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.2.1 Exceptions-In Sections 4, 7, and 8, the apparatus used is only available in SI units. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This 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.
