ASTM D1414 – Rubber O-Ring Tensile Strength Testing
ASTM D1414 (D 1414) covers multiple properties of O-Rings. Part of the specification includes tension testing for determining the breaking force, tensile strength, and ultimate elongation of an o-ring. The tension test is intended to be performed on a ...
How to Perform an ASTM D638 Plastic Tensile Strength Test
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...
