Salt Spray Testing: Complete Guide, Standards, and Chamber Selection
What is Salt Spray Testing?Salt spray testing (also known as salt fog testing) is an accelerated corrosion testing method used to evaluate how materials, coatings, and metal components perform in corrosive environments.By exposing samples to a controlled salt mist environment, engineers can simulate years of real-world corrosion (such as coastal or road salt exposure) within days or weeks. This makes salt spray testing a critical tool in product validation and supplier qualification.
