The ISO 22848 standard specifies a test method for measuring the stress corrosion crazing rate of steel and alloys under static load conditions in high temperature water. This method is suitable for materials such as stainless steel, nickel-based alloys, low-alloy steels, carbon steel, etc., especially for the test scenario of simulated water environment in light water reactors. The test calculates the crazing rate by applying a static load in a high voltage kettle and monitoring the change of the sample crazing length by potential drop method (PDM). This standard provides a scientific basis for the evaluation of corrosion performance of metal materials in the nuclear industry, chemical industry and other fields, and is helpful for material selection and structural safety design.
