Understanding the Basics of ASTM B117 Salt Spray Test Chambers

An ASTM B117 salt spray test chamber is a specialized laboratory environment used to evaluate the corrosion resistance of metals in simulated outdoor environments. In other words, it’s a space where corrosion testing is conducted. Sometimes referred to as salt fog, a salt spray test is conducted in a closed chamber that can be adjusted to create a variety of corrosive environments.

Salt spray testing is a common method used to predict the corrosion rates of metals in outdoor environments such as seawater, chlorides, and/or other outdoor elements.
