Scope

Scope: This document specifies the terms and definitions, symbols and explanations, principles, test equipment, specimens, test procedures, result evaluation, data rounding of test results, and test reports for determining the tensile strain hardening properties of metal materials under quasi-static conditions at room temperature. This document is applicable to the part of the test where the stress-strain curve shows a monotonically increasing trend within the range of tensile plastic deformation, and it is used to determine the tensile strain hardening index (referred to as the "n value"), the instantaneous strain hardening index during uniform deformation (referred to as the "instantaneous n value"), and the instantaneous tensile strain hardening rate (referred to as the "instantaneous hardening rate m"). After consultation with relevant parties, other temperature tests can also be conducted in accordance with this document.
