GB/T 19745-2005
ActiveCorrosion tests in artificial atmosphere at very low Concentrations of polluting gas(es)
人造低浓度污染气氛中的腐蚀试验
Application Summary AI generated
This standard specifies test methods for evaluating the corrosion resistance of metals and coatings when exposed to artificial atmospheres containing very low concentrations of specific polluting gases, such as hydrogen sulfide or sulfur dioxide. It is primarily applied in the metallurgy and materials testing industries to simulate mild, long-term environmental exposure, particularly for electronic components, precision instruments, or automotive parts in controlled laboratory conditions. The standard helps predict material performance in indoor or semi-enclosed environments where trace pollutants cause gradual corrosion.
