ASTM D4073/D4073M-06(2019)e1
(Test Method)Standard Test Method for Tensile-Tear Strength of Bituminous Roofing Membranes
Standard Test Method for Tensile-Tear Strength of Bituminous Roofing Membranes
SIGNIFICANCE AND USE
4.1 Determining the tensile-tear strength of laboratory and field samples of roofing membranes should be useful in developing performance criteria, and as one basis for comparison of different materials and systems. The effects of temperature, moisture, and aging may be evaluated by appropriate selection of field samples or conditioning of laboratory samples, and tests may be conducted in an environmental chamber.
SCOPE
1.1 This test method covers the determination of the tensile-tear strength of bituminous roofing membranes.
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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 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.
