ASTM D7121
Standard Test Method for Rubber Property—Resilience Using Schob Type Rebound Pendulum


ASTM D7121 establishes a test method for determining tensile strength and elongation at break of thin films and sheets in elastomers and plastics through uniaxial tensile testing. The standard applies to various polymeric materials, including vulcanized rubbers, thermoplastic elastomers, and plastics, using standardized test specimens. The procedure involves applying controlled tensile force until specimen failure, measuring maximum load and percentage elongation to provide essential mechanical property data for evaluating the quality and performance characteristics of elastomeric and plastic products.
