Paints & Varnishes – Determination of Resistance to neutral salt spray (fog)
Can be used to test the relative resistance to corrosion of paints and varnishes, when exposed to a salt spray (fog) 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 2.5ml/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 400 Litres are not permitted by this test standard.
This test is also referred to as a Neutral Salt Spray or NSS test.

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’.
