scope:

This part of IEC 61347 specifies particular safety requirements for battery supplied electronic control gear for maintained and non-maintained emergency lighting purposes. It includes specific requirements for electronic control gear and control units for self-contained luminaires for emergency lighting as specified by IEC 60598-2-22. It is intended for control gear for fluorescent lamps, but it is also applicable to other lamp types e.g. incandescent, high pressure discharge lamps and LED's. This standard covers the emergency mode operation of a control gear. For control gear with a combination of normal and emergency lighting operation, the normal lighting operation aspects are covered by the appropriate part 2 of IEC 61347. d.c. supplied electronic control gear for emergency lighting may or may not include batteries. This standard also includes operational requirement for electronic control gear, which, in the case of d.c. supplied electronic control gear, are regarded as performance requirements. This is because non-operational emergency lighting equipment presents a safety hazard. It does not apply to d.c. supplied electronic controlgear for emergency lighting, which are intended for connection to a centralised emergency power supply system. A centralised emergency power system could be a central battery system. NOTE Annex J of IEC 61347-2-3 applies to a.c, a.c./d.c. or d.c. supplied electronic control gear for connection to centralised emergency power supply systems that are also intended for emergency lighting operation from a.c/d.c. supplies.
