Salt Spray (Fog) Corrosion Exposure Testing

What is Salt Spray Testing?

Salt spray testing provides a controlled accelerated corrosive environment to evaluate the relative corrosion resistance of the coating, substrate, or part itself. Parts or panels are placed inside a chamber and exposed continually for a specified period of time, then evaluated for resistance to corrosion. This type of testing is also known as salt fog testing.
