Application Summary AI generated
GB/T 20854-2007 specifies an accelerated corrosion test method that cycles metal and alloy specimens through salt mist, dry, and wet conditions to simulate realistic corrosive environments. It is applied in the automotive, aerospace, and coatings industries to evaluate the corrosion resistance of materials and protective coatings under fluctuating humidity and salt exposure. This standard is used for quality control and material selection in product development and manufacturing.
