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.
1.1 This test method covers the determination of the tensile-tear strength of bituminous roofing membranes.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
