This part of IEC 60364 applies to electrical installations with regard to measures for the protection of persons, livestock and property against
– thermal effects, combustion or degradation of materials, and risk of burns caused by electrical equipment,
– flames in case of a fire hazard being propagated from electrical installations to other fire compartments segregated by barriers which are in the vicinity, and
– the impairment of the safe functioning of electrical equipment including safety services.
NOTE 1 For protection against thermal effects, national statutory requirements may be applicable.
NOTE 2 Protection against overcurrent is dealt with in IEC 60364-4-43.
In respect of cables and their reaction to fire, these protective measures can be expressed by reference to the Construction Products Regulation (CPR), and the relevant classes according to EN 13501 6.
NOTE 3 Whilst the CPR requires the manufacturer to declare the reaction to fire performance of the cable in accordance with procedures and classifications that are common across the EU, it is the responsibility of the Member State to determine which classification is required for any particular application or installation. National statutory requirements could therefore override the levels quoted here.
