Significance and Use
4.1 Several test methods for measuring mass loss by abrasion and impact of preformed block-type and preformed pipe-covering-type thermal insulation have been used previously. It is believed that no single test method completely covers all factors involving such forces for different kinds of materials, but this test method is intended to provide a procedure that gives reproducible results. It is used for comparing the mass loss by tumbling before and after a specific treatment of the insulation, as agreed upon by the purchaser and the manufacturer.
1.1 This test method covers determination of the mass loss of preformed block-type and preformed pipe-covering-type thermal insulation as a result of a combination of abrasion and impact produced by a laboratory tumbling mechanism.
1.2 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.
1.3 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.
