Introduction to the New Standard for Tensile Testing Method of Metallic Materials

For the actuality that the new standard “GB/T 228-2002 Tensile Testing Method of Metallic Materials at Ambient Temperature” has not been adequately carried out, this paper gives a brief introduction to the new standard based on engineering requirements, including basic content of the new standard, and the names, symbols, glossaries and basic meanings of mechanical properties in both old and new standards, lists a useful comparison table of names and symbols of mechanical properties in both old and new standards, and presents a criterion for replacing the old names and symbols with new ones.
