Corrosion & related property tests – copper accelerated acetic acid salt spray test
Can be used to test the relative resistance to corrosion of metallic coatings, when exposed to a copper accelerated acetic acid salt spray climate at an elevated temperature.
Test specimens are placed in an enclosed chamber and exposed to a continuous indirect spray of acidified (pH 3.1to 3.3) salt water solution, which falls-out on to the specimens at a rate of 1.0 to 2.0ml/80cm²/hour, in a chamber temperature of +50C. This climate is maintained under constant steady state conditions. The test duration is variable.
This test is also referred to as a CASS test.
Chamber volumes of less than 200 Litres are not permitted by this test standard.
