4.2 Tests
Verification of resistance to heat
a) for surface mounting boxes, separable covers, separable cover plates and separable frames by the test of 4.2.3;
b) for accessories, with the exception of the parts, if any, covered by 1), by the tests of 4.2.1,4.2.2 and, with the exception for the accessories made from natural or synthetic rubber or a mixture of both, by the test of 4.2.3.
4.2.1 The specimens are kept for 1 h in a heating cabinet at a temperature of 100 °C ± 2 °C.
During the test, they shall not undergo any change impairing their further use, and sealing compound, if any, shall not flow to such an extent that live parts are exposed.
After the test and after the specimens have been allowed to cool down to approximately room temperature, there shall be no access to live parts which are normally not accessible when the specimens are mounted as in normal use, even if probe B of IEC 61032 is applied with a force not exceeding 5 N.
After the test, markings shall still be legible.
Discoloration, blisters or slight displacement of the sealing compound is disregarded provided that safety is not impaired within the meaning of the relevant standard.
4.2.2 Parts of insulating material necessary to retain current-carrying parts and parts of the earthing circuit in position are subjected to a ball-pressure test according to IEC 60695-10-2, except that the insulating parts necessary to retain the earthing terminals in a box shall be tested instead to the test as specified in 4.2.3.
