This test shall be carried out in accordance with IEC 60068-2-11, Test Ka: Salt mist and this has been superseded by EN 60068-2-11. Please see elsewhere in this section for a description of this test.

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.

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’.
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’.
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’.
