Systèmes de transfert de puissance sans fil (WPT) Pour véhicules électriques — Partie 1: Exigences générales.
The above requirement may be met by any method that ensures that none of the test objects can reach a temperature that exceeds the above limits. Such methods include, but are not limited to, ensuring that the power density is low enough to not cause the test object to exceed that level, or suspending system operation until the foreign object has been removed.
11.7 Resistance to abnormal heat and fire due to internal electric effects
11.7.1 General
Parts of insulating materials which might be exposed to thermal stresses due to internal electrical effects, and the deterioration of which might impair the safety of the supply device, shall not be adversely affected by normal (operational) heat, abnormal heat or fire.
11.7.2 Resistance of insulating materials to heat
Insulating materials shall be selected either by reference to the insulation temperature index
according to the methods of IEC 60216 (all parts) or by compliance with IEC 60085.
11.7.3 Resistance of insulating materials to abnormal heat and fire due to internal electric effects
Insulating materials used for parts necessary to retain current carrying parts in position and parts which might be exposed to thermal stresses due to internal electrical effects, and the deterioration of which might impair the safety of the supply device, shall not be adversely affected by abnormal heat and fire and shall be verified by the glow-wire test as specified in IEC 60695-2-12. For the purpose of this test, a protective conductor is not considered as a current-carrying part.
For small parts (having surface dimensions not exceeding 14 mm x 14 mm), an alternative test may be used (e.g. needle flame test, according to IEC 60695-11-5). The same procedure may be applicable for other practical reasons where the metal material of a part is large compared to the insulating material.IEC 61980-1-2020 pdf free download.
