Description
CASS stands for Copper-Accelerated Acetic Acid Salt Spray. salt spray chambers is a standardized test method used to evaluate the corrosion resistance of metallic coatings and materials. The CASS test involves exposing the test specimen to a salt spray solution consisting of acetic acid and sodium chloride, with the addition of copper chloride to accelerate the corrosion process.
The test is typically conducted in a controlled salt spray chamber where the specimens are exposed to the salt spray for a specified period of time, while being monitored for signs of corrosion such as rust, discoloration, or loss of coating adhesion. The length of the test period can vary depending on the materials being tested, but is typically between 24 and 72 hours.
The CASS test is often used in industries such as automotive, aerospace, and electronics, where corrosion resistance is critical for the durability and longevity of components and products. It is one of several standard test methods available for evaluating corrosion resistance, with others including the salt spray test, the humidity test, and the cyclic corrosion test.
