ASTM G31—Standard for Laboratory Immersion Corrosion of Metals

Detection purpose: corrosion rate of metal in special medium solution

Detection range: all kinds of stainless steel and alloy

Requirements for full immersion corrosion test samples:

The total surface area of the sample is not less than 1000mm2, 3 pieces

Medium and test cycle provided by customer

Total immersion corrosion involves test standards:

ASTM G31 Standard for Laboratory Immersion Corrosion of Metals

JB/T 6073-1992 Metal coating. Laboratory complete immersion corrosion test

HB 5194-1981 Periodic immersion corrosion test method

GB 10124-1988 Metal material laboratory uniform corrosion full immersion test method

JB/T 7901-1999 Metals materials -- Uniform corrosion -- Methods of laboratory immersion testing

This standard specifies the scope of application, reference standards, samples, test devices, test solutions, test time, test conditions and procedures, test results and test reports of the uniform corrosion full immersion test method for metallic materials laboratories. This standard is applicable to evaluate the uniform corrosion performance of metallic materials in full immersion test.
