GB/T 38231-2019: Corrosion of metals and alloys - Test method for thermal-cycling exposure oxidation testing under high-temperature corrosion conditions for metallic materials
This Standard stipulates the equipment, gas supply, samples, test process, calculation and analysis of mass change, post-test sample evaluation and test report of isothermal exposure oxidation testing of metallic materials under high-temperature corrosion conditions. This Standard is applicable to test method for thermal-cycling corrosion testing (namely, cyclic oxidation test) of metallic materials from the ambient temperature to high- temperature gas environment (each sample shall receive a series of repeated, regular and controlled temperature cycles). After proper adjustments are made, the test method may also be adopted in the testing of other materials. This Standard is not applicable to testing that adopts extremely short holding time (a few minutes or a few seconds).
