ASTM D412 | Plastics and Elastomers | Tension Testing
ASTM D412 covers the testing of tensile properties of thermoset rubbers and thermoplastic elastomers. The specification describes two test methods: A and B. Method A is common and can be performed on a universal testing machine (tensile testing machine). If you are going to perform this test, you should read the entire specification from ASTM. This is a quick summary to decide if ASTM D412 is right for you and to point out what equipment you need to perform the test.
Prior to conducting ASTM D412, it is important to read the entire specification in the relevant ASTM publication.
