ISO 3769

Corrosion testing of metallic coatings – acetic acid salt spray test

Can be used to test the relative resistance to corrosion of metallic coatings, when exposed to an 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 +35C. This climate is maintained under constant steady state conditions. The test duration is variable.

Chamber volumes of less than 200 Litres are not permitted by this test standard.

This test is also referred to as an ASS test.

ISO 3768

Corrosion testing of metallic coatings – neutral salt spray test

Can be used to test the relative resistance to corrosion of metallic coatings, when exposed to a salt spray climate at an elevated temperature.

Test specimens are placed in an enclosed chamber and exposed to a continuous indirect spray of neutral (pH 6.5 to 7.2) 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 +35C. This climate is maintained under constant steady state conditions. The test duration is variable.

Chamber volumes of less than 200 Litres are not permitted by this test standard.

This test is also referred to as an NSS test.

Test specimens are placed in an enclosed chamber and exposed to a continuous indirect spray of neutral (pH 6.5 to 7.2) 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 +35C. This climate is maintained under constant steady state conditions. The test duration is variable.

This test is also referred to as a Neutral Salt Spray or NSS test.

EN ISO 4541

Metallic and other non-organic coatings – Corrodkote (CORR) test

This test involves the application of a slurry containing corrosive salts to test specimens, exposing them to a high relative humidity for a specified period of time.

The slurry is prepared by dissolving 0.035g of reagent grade copper nitrate trihydrate, 0.165g of reagent grade iron chloride hexahydrate, and 1.0g of reagent grade ammonium chloride in 50ml of distilled water and stirring into the solution 30g of water washed ceramic grade kaolin. This mixture is applied to the test specimens and placed inside an enclosed chamber at 35°C having an exposure zone of between 80 to 90% RH.
