ASTM D4073 – Standard Test Method for Tensile-Tear Strength of Bituminous Roofing Membranes
Description:
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.
