GB/T 31588.1-2015 "Paints and varnishes — Determination of resistance to cyclic corrosion conditions — Part 1: Wet (salt fog)/dry/humidity" is applicable to the testing of the cyclic corrosion resistance of coatings, simulating corrosive environments with alternating salt fog, drying, and humidity conditions. A cyclic corrosion test chamber is used to control the environmental parameters of each stage. After the test cycle is completed, a colorimeter is used to measure the color difference of the coating, and a magnifying glass is used to observe defects such as rust and blistering. The corrosion level is evaluated according to the standard, providing a scientific method for assessing the weather resistance of coatings.
