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.
