ASTM D7275-07

Standard Test Method for Tensile Properties of Bituminous Geomembranes (BGM)

SIGNIFICANCE AND USE
This method is used to evaluate the tensile properties of BGM. It can be used for manufacturing quality control or acceptance testing.
This test method uses a dumbbell specimen. The shape and dimensions of the specimen are defined in this standard. No other shape or dimensions are allowed. Other mechanical properties of BGM may be measured using different test methods. Refer to Guide D 6455.
The reported properties are the maximum strength and elongation at maximum strength.
SCOPE
1.1 This test method is used to measure the tensile properties of bituminous geomembranes (BGM) using a dumbbell shape specimen.
1.2 The values stated in SI units are to be regarded as 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.
