Kesternich test

This test was developed in 1951 by Wilhelm Kesternich[1] to simulate the damaging effects of acid rain.

Kesternich testing, or sulfur dioxide testing, simulates acid rain or industrial chemical exposure to evaluate the relative corrosion resistance of the coating, substrate, or part itself.

The door or hood of the chamber is tightly closed and hermetically sealed for safety.
