ASTM-D412 – Standard Test Methods for Vulcanized Rubber and Thermoplastic Elastomers—Tension
The test methods detailed in this standard evaluate the tensile properties of thermoplastic elastomers and vulcanized thermoset rubbers. There are two separate test methods, which produce differing results:
Test Method A – Dumbbell and Straight Section Specimens
Test Method B – Cut Ring Specimens
This test method is designed to assess materials and products which are required to withstand tensile forces during their performance cycle.
Tensile properties depend on the material, and therefore the effects of the test will vary. There are also several test conditions which can alter results, including:
