This standard specifies a test method for determining the stress corrosion crack (SCC) growth rate of steels and alloys under static-load conditions in high-temperature water, such as simulated water environment of light water reactors. The crack length of the specimen is monitored by a potential drop method (PDM) during the test, when a fracture mechanics specimen is used to conduct the test in an autoclave. The test method can be applied to stainless steels, nickel base alloys, low alloy steels, carbon steels and other alloys.
