The BMW AA-0324 standard is used to test the corrosion protection effect of metallic materials in a salt fog environment. The test evaluates the durability of the anti-corrosion system by continuously spraying the sample with neutral saline water in a closed environment. The test conditions include a temperature of 35 ° C or 50 ° C and the spray volume of the saline solution to simulate the corrosion environment in actual use. The standard is based on ISO 9227 and is suitable for evaluating the relative anti-corrosion performance of anti-corrosion systems.
