GB/T 20120.2-2006 "Corrosion of metals and alloys, corrosion fatigue test, Part 2: Pre-crazing test crazing expansion test" specifies the method of using pre-crazing specimens to carry out fatigue crazing expansion test of metals and alloys. The standard specifies the test principle, specimen preparation, equipment requirements, test procedures, data collection and analysis, and result evaluation process. By quantifying the crazing expansion rate, it provides technical specifications and uniform standards for evaluating the crazing expansion behavior of materials under the synergistic effect of corrosion and fatigue, and predicting the life of components.
