This standard specifies the methods and requirements for testing creeping crazing and creeping-fatigue crazing expansion rate of metal materials under creeping load and creeping-fatigue cyclic load. It is applicable to the testing of creeping crazing initiation time and expansion rate of metal homogeneous materials and metal welded joints at constant temperature; It is applicable to the determination of creeping fatigue crazing expansion rate of metal homogeneous materials under uniaxial cyclic load. The test process and data processing method are specified in detail by means of symbols and descriptions, test principles, sample design, test procedures, test result processing and test reports.
