GB/T 14293-1993 "Corrosion Test in Artificial Atmosphere, General Regulations" is a national standard, specifying the general method and process of corrosion testing in artificial atmospheric environments. The content covers the test principle (simulating industrial, marine and other corrosive environments), equipment requirements (corrosion test chamber, environment control device), sample preparation (material pretreatment, size specifications), test conditions (temperature, humidity, pollutant concentration control) and operation steps (period setting, observation records). The standard applies to the evaluation of corrosion resistance performance of metal and Non-metallic materials, provides technical specifications for simulating corrosion behavior in actual service environments, and helps to unify test methods, improve data comparability, and guide material selection and protection process optimization.
