ACCELERATED LIFE TESTING

CASS Test -- Copper-Accelerated Acetic Acid Salt Spray (Fog) Test (ASTM B368, B117)

Touchstone has several salt spray cabinets, and can perform both standard and customer-specified testing to ASTM B 117, ASTM B 368, ASTM G 85 and other specifications.

This test is performed according to ASTM Test Method B 368. It is performed using a standard ASTM B 117 salt fog cabinet, but the fog solution is mixed and acidified with acetic acid to a pH between 3.1 and 3.3. Copper chloride is then added to the salt solution. The solution is atomized as a fog into the cabinet which is maintained at 120° F (49° C). This test is used to determine corrosion resistance of various aluminum alloys. It is also used for testing of chromium plating on zinc and steel die castings.
