ISO 6270-2 Determination of Moisture Resistance of Paints and Varnishes - Test Procedure for Exposure of Test Samples to Condensate Atmospheres

ISO 6270-2 describes the general conditions and procedures that must be observed when testing coated test specimens in stable condensate atmospheres or varying condensate atmospheres to ensure the results of tests performed in different laboratories are verified.

It does not cover the shape and preparation of test specimens, the duration of the test, or the evaluation of test results.

Condensate test environments are determined as follows:

CH - Condensation atmosphere with constant humidity

AHT - Condensation atmosphere with variable humidity and air temperature

AT - Condensation atmosphere with variable air temperature

Limitations, temperature and humidity are important parameters that affect test results. Deviations from the stated requirements can lead to non-comparable results. However, interested parties can agree on alternative parameters and these parameters are reported.

In principle, a coated test sample is exposed to condensation in a climate chamber and the effects of exposure are evaluated according to criteria previously agreed between the parties concerned, these criteria are often subjective.

Among the services provided by our organization within the framework of paint and varnishes testing services, there are also ISO 6270-2 standard tests.
