GB/T 2423.17-2024 "Environmental Testing - Part 2: Test Methods - Test Ka: Salt Spray" is applicable for evaluating the corrosion resistance of protective coatings such as metallic coatings and conversion coatings. It employs a sodium chloride solution with a concentration of 50 ± 5 g/L and a pH value of 6.5–7.2. The temperature inside the test chamber is maintained at 35 ± 2°C, and the salt spray settlement rate is controlled at 1.0–2.0 mL/(80 cm²·h). The test duration is divided into multiple levels. Through simulation in a neutral salt spray environment, the protective ability of the coating for the base metal is assessed.
