ASTM D1117 - Tear Resistance
The guide directs users to select test method ASTM D5733 to determine tearing strength in the trapezoidal configuration. The method is performed on a tensile tester on a trapezoid shaped sample with a small cut added to evaluate the force required to continue the propagation of the tear. This uses the same test apparatus as ASTM D5034 but with a different attachment device and sample orientation.
