This standard is a method standard for testing the performance of rubber materials. It describes a method for determining the strength of raw rubber or unvulcanized rubber compounds through tensile stress-strain testing. The compound strength is an important indicator for evaluating the ability of unvulcanized rubber compounds to resist permanent deformation during processing and the storage of semi-finished products. The core testing instrument for this method is a tensile testing machine that meets the requirements of ISO 5893. The test specimens must be cut from standard sheets or directly molded in accordance with specified procedures. This standard is equivalent to the latest international standard and aims to unify and standardize testing processes, providing a reliable basis for quality control of raw materials and optimization of production processes in the rubber industry.
