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.

EN 60068-2-11 Environmental testing Part 2 Tests – Test Ka: salt mist
Can be used to test the relative resistance to corrosion of protective coatings, when exposed to a salt mist (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.
This test is also referred to as a Neutral Salt Spray or NSS test.

Procedure for exposing test specimens in condensation-water atmospheres.
ISO 6270-2 (CH)
This test standard replaces and is similar to DIN 50 017*.
Test ‘CH’ (condensation atmosphere with constant high humidity) – requires constant conditions of +40°C and constant condensation humidity level of c.100%RH.
* The correlation between the above 6270-2 test method and the DIN 50 017 test methods, is:
6270-2 method ‘CH’ is equivalent to DIN 50 017 method ‘KK’.
Procedure for exposing test specimens in condensation-water atmospheres.
ISO 6270-2 (AHT)
This test standard replaces and is similar to DIN 50 017*.
Test ‘AHT’ (condensation atmosphere with alternating humidity & air temperature) – requires changing temperature conditions of 40°C to 18-28°C, during which humidity changes from condensation level of c.100%RH towards ambient humidity level.
* The correlation between the above 6270-2 test method and the DIN 50 017 test methods, is:
6270-2 method ‘AHT’ is equivalent to DIN 50 017 method ‘KFW’.
Procedure for exposing test specimens in condensation-water atmospheres.
ISO 6270-2 (AT)
This test standard replaces and is similar to DIN 50 017*.
Test ‘AT’ (condensation atmosphere with alternating temperature only) – requires 40°C reducing to 18-28°C, while maintaining a condensation humidity level of c.100%RH.
* The correlation between the above 6270-2 test method and the DIN 50 017 test methods, is:
6270-2 method ‘AT’ is equivalent to DIN 50 017 method ‘KTW’.
