ASTM D953 is a test method that covers the determination of the pin-bearing strength of rigid plastics in either sheet form, molded form, or in reinforced thermoset form. Procedures A and B are applicable for thermoplastic materials in tension loading and compression loading respectively. Procedure C is applicable for thermoset reinforced plastics.
Before conducting ASTM D953, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
