Testing standards

Salt spray testing simulates a salt spray environment to test the corrosion resistance of product surface coatings, metal materials, etc. There are various common standards. Internationally, ISO 9227 has formulated relevant specifications for salt spray test of artificial atmosphere corrosion test, which specifies key parameters such as salt solution concentration, pH value, spray mode, etc., and is applicable to salt spray corrosion test of various metal and non-metallic coatings. The ASTM B117 standard developed by the American Society for Testing and Materials is a classic standard in the field of salt spray testing, widely used in industries such as automotive and aerospace, with clear requirements for testing equipment, operating procedures, and result evaluation. In China, GB/T 10125 "Corrosion Test in Artificial Atmosphere - Salt Spray Test" is equivalent to ISO 9227 standard. Combining with the actual situation in China, detailed specifications have been made for each link of salt spray testing to ensure the standardization and consistency of the testing. According to different testing purposes and product characteristics, salt spray testing is divided into neutral salt spray test (NSS), acetic acid salt spray test (AASS), and copper accelerated acetic acid salt spray test (CASS) to simulate different corrosion environments.

Applicable products

Automotive components: The body, chassis, wheels, and other parts of a car are exposed to outdoor environments for a long time and are susceptible to salt spray erosion. Through salt spray testing, car manufacturers can evaluate the corrosion resistance of components, optimize product design and surface treatment processes, extend the service life of cars, and improve the reliability of vehicles in harsh environments such as coastal areas and winter salt roads.

Aerospace equipment: Aircraft will travel through different climate zones during flight, and some components will come into contact with salt spray in oceanic climates. The key components of aerospace equipment, such as engine blades, landing gear, etc., require strict salt spray testing to ensure their safety and reliability in complex environments and ensure flight safety.

Electronic devices: The casing and internal circuits of electronic devices such as smartphones and tablets are prone to corrosion in humid salt spray environments, leading to device malfunctions. Salt spray testing helps electronic device manufacturers verify the protective performance of their products, adopt appropriate protective measures, avoid economic losses caused by salt spray corrosion, and improve product quality.

Building materials: Building hardware, door and window frames, curtain walls, and other building materials that are exposed to natural environments for a long time may rust and be damaged by salt spray, affecting the aesthetics and safety of the building. Salt spray testing can help building material suppliers and construction companies choose materials with good corrosion resistance, ensuring the stability and durability of building structures.
