The ISO 10062-2022 standard defines a method for testing the corrosion effects of very low concentrations of gases on metals and alloys in an artificial environment. The standard specifies the use of gases with a volume fraction not exceeding 10 − 6 to simulate the contaminated environment under specific temperature and relative humidity conditions to evaluate the corrosion performance of metallic materials. The method is applicable to metals and their alloys, metallic coatings and organic coatings and is designed to ensure the reproducibility of test results and improve adaptability to different gas combinations. The standard focuses on test conditions that avoid condensation and is not used to rank materials in comparison or predict long-term corrosion resistance.
