The ISO 11503:1995 standard specifies a method for determining the temperature resistance of coatings under intermittent water condensation. This test is used to assess the performance of paints or related materials under specific temperature and Humidity conditions, particularly on non-porous and porous substrates. The test method provides a means of checking whether the coating mass meets the standard, and while the results cannot be used directly to infer the performance of coatings in all environments, it helps to test the tolerance of coatings in practical use.
