Why Test Connectors in Salt Spray Environments?

2026-01-21

Salt spray environments primarily refer to the application conditions of connectors used in medical devices, electric vehicles, and underwater equipment. Under standard testing conditions, a salt spray environment is typically created using a 5% salt solution. This environment is commonly employed to effectively evaluate the performance of equipment or components directly exposed to marine or terrestrial salt-rich conditions, though it does not replicate a real-world setting exactly. Standard exposure times range from 48 to 96 hours.

Salt spray testing is often applied to underwater environments and is widely used to assess the corrosion resistance of metal connector housings—such as verifying the protective effect of nickel plating on zinc alloy die-cast surfaces. After exposure, performance is evaluated by checking Dielectric Withstanding Voltage (DWV) and insulation resistance to confirm the effectiveness of housing seals.

Salt spray testing is also sometimes used in the evaluation of automotive connectors. When a car or truck is in motion, board-to-board connectors in certain locations may come into contact with water splashed from tires, especially in northern winters where roads are treated with salt to accelerate snow melting. These connectors generally undergo salt spray testing to verify their corrosion resistance. The validation criteria typically focus on the reliability of contact resistance rather than visual inspection. In many cases, such connectors are used with sealing rings to enhance their resistance to salt spray.
