Historical Standard: ASTM C421-00 Standard Test Method for Tumbling Friability of Preformed Block-Type Thermal Insulation
SUPERSEDED (see Active link, below)
ASTM C421
1. Scope
1.1 This test method covers determination of the mass loss of preformed block-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 the standard. The values in parentheses are provided 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.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
