WG 10 - TC 121/SC 121A/WG 10

IEC TR 63054:2017(E) applies to the fire risk analysis of low-voltage switchgear and controlgear (hereinafter referred to as "equipment") referring to the IEC 60947 relevant publications, where the following applies:
- only the case where a fire originates (typically under fault or misuse conditions) within the equipment;
- only equipment installed in normal environments. Hazardous environments, for example in presence of combustible materials, is not to be considered;
- only the case of products selected, installed and used according to the manufacturer instructions and installation rules.
In addition, the following cases are not considered:
- faults addressed by IEC TR 61641;
- risks due to smoke emissions;
- double faults, i.e. multiple phenomenon, potentially combined.

Applies, when required by the relevant product standard, to switchgear and controlgear hereinafter referred to as "equipment" and intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c. It states those general rules and requirements which are common to low-voltage equipment as defined in Subclause 1.1, including for example: definitions, characteristics, information supplied with the equipment, normal service, mounting and transport conditions, constructional and performance requirements, verification of characteristics and performance.
