ASTM D5147/D5147M : 18(2024)

Standard Test Methods for Sampling and Testing Modified Bituminous Sheet Material

Standard Details

1.1 These test methods cover procedures for sampling and testing prefabricated, reinforced, polymer-modified bituminous sheet materials designed for single or multiple-ply application in roofing and waterproofing membranes. These products may use various surfacing materials on one side.

1.2 These test methods cover a number of different products. Not all tests are required for every product. Only those called out in the product standard are required.

1.3 These test methods appear in the following order:

	Section
Sampling	4
Conditioning	5
Thickness	6
Load Strain Properties	7
Tear Strength	8
Moisture Content	9
Water Absorption	10
Dimensional Stability	11
Low-Temperature Flexibility	12
Heat Conditioning	13
Accelerated Weathering	14
Granule Embedment	15
Compound Stability	16
Coating Thickness	17
Low Temperature Unrolling	18
Precision and Bias	19

1.4 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 nonconformance with the standard.

1.5 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.

1.6 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.
