ASTM D624 | Plastics and Elastomers | Tension Testing
ASTM D624 is a testing standard for measuring the tear strength of thermoset rubbers, thermoplastic elastomers, and silicones. This standard describes multiple different types of sample shapes (Type A, B, C, T, and CP) that can be tested in a standard universal testing machine. Usually materials that are tested to D624 are also tested according to specification ASTM D412 to measure the tensile strength and elongation.
ASTM D624 measures the force per unit thickness required to rupture or start a tear through the sample. Prior to conducting ASTM D624, it is important to read the entire specification in the relevant ASTM publication.
