GB/T 12085.4-2022 specifies the environmental test methods for salt spray testing of optical and photonic instruments and their components, primarily used to evaluate the corrosion resistance of optical and functional coatings on product surfaces in salt spray environments. The purpose of the test includes inspecting the anti-corrosion effectiveness of coatings and identifying potential issues that may arise when different materials are combined. The core testing instrument for conducting this test is the salt spray test chamber. Its supporting detection and auxiliary equipment may include a salinometer for measuring the concentration of the salt solution, a pH meter for monitoring environmental pH levels, and a drying oven for post-treatment of test samples.
