This Part of EN 13523 specifies the procedure for determining the behaviour of an organic coating on a metallic substrate when submitted to accelerated ageing by heating at a defined temperature for a defined period of time.

It is not possible to test heat resistance in such a way as to control all possible conditions of use. The aim of this test is therefore to furnish the basic test method for the effect of heat.

Special applications might require that properties other than those mentioned in this Part of EN 13523 be checked. The test(s) to be done should then be agreed between the interested parties.
