ASTM D1865-89(2002)

Standard Test Method for Hardness of Mineral Aggregate Used on Built-Up Roofs

SIGNIFICANCE AND USE
This test method measures the resistance to physical breakdown in handling of built-up roofing aggregates.
SCOPE
1.1 This test method covers the determination of hardness of all types of mineral surfacing for use on built-up roofs and is intended to provide an index of their ability to withstand physical breakdown in handling.
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.
