Scope
This standard specifies the method for tensile testing of sintered metal materials at room temperature, including the principle, symbols and explanations, specimens, testing equipment, testing steps, calculation of test results, rounding of numerical values, and test reports. This standard is applicable to the determination of the yield strength, specified plastic elongation strength, tensile strength, elongation after fracture, and cross-sectional contraction rate of sintered metal materials (except for hard alloys) that have been machined or not machined.
