GB/T 15957-1995 "Classification of atmospheric environment corrosivity" stipulates the classification method of atmospheric environment corrosivity. The standard divides the atmospheric environment corrosivity into different grades based on atmospheric environmental factors (such as humidity, pollutant content, etc.), and clarifies the environment parameters and corrosion characteristics corresponding to each grade. It provides a scientific basis for evaluating the corrosion effect of the atmosphere on materials, guiding protection design and material selection, and helping to improve the durability of materials in the atmospheric environment.
