GB/T 39635-2020 Metallic materials—Measurement of indentation tensile properties and residual stresses by an instrumented indentation test (English Version)
This document specifies the terms and definitions, symbols and descriptions, test principles, testing machines, samples, test procedures, uncertainty of results, test reports, etc. . This document applies to the instrumented indentation method for the determination of indentation tensile properties and residual stresses of metallic materials. The instrumented indentation test conforms to the classification of GB/T21838.1, which belongs to the macro scope, and the indentation test force is 2N~3kN.
