It includes specific requirements for electronic controlgear and control units for self-contained luminaires for emergency lighting as specified by IEC 60598-2-22. This third edition cancels and replaces the second edition published in 2006. It constitutes a technical revision. Significant changes introduced into this third edition include:- modification of IEC 61347-2-7 to become a standard exclusively for d.c. battery supplied electronic controlgear for emergency lighting (self-contained) IEC 61347-2-3 Annex J is intended to cover centrally supplied emergency controlgear; - update of Clause 22 - Recharging devices; - modification of Clause 20 battery voltage characterisation to support EBLF measurement. This to simplify and increase reproducibility of testing; - rationalisation of requirements between IEC 61347-2-7 and IEC 60598-2-22 requirements of IEC 60598-2-22 being transferred to IEC 61347-2-7.
