ASTM D638 is one of the most common plastic strength specifications and covers the tensile properties of unreinforced and reinforced plastics.  This test method uses standard "dumbell" or "dogbone" shaped specimens under 14mm of thickness.  A universal testing machine (tensile testing machine) is needed to perform this test.  If you are going to perform this test, you should read the entire specification from ASTM. This is a quick summary to decide if this test is right for you, and to point out what equipment you need to perform the test.

ASTM D412 ( D 412 ) covers the 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 this test is right for you, and to point out what equipment you need to perform the test.
