ASTM D451/D451M-91(2013)e1
(Test Method)Standard Test Method for Sieve Analysis of Granular Mineral Surfacing For Asphalt Roofing Products
Standard Test Method for Sieve Analysis of Granular Mineral Surfacing For Asphalt Roofing Products
SIGNIFICANCE AND USE
4.1 This test method is used to determine the grading of materials used as granular mineral surfacing. The results are used to determine compliance of the particle size distribution with applicable specification requirements.
SCOPE
1.1 This test method covers the determination of the particle size distribution of granular mineral surfacing material such as crushed slate, stone, coated granules, and so forth, used on the weather surface of prepared asphalt roofing and shingles.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the 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.
