CEI/IEC-61347-2-7:2006 pdf free download.Lamp controlgear – Part 2-7: Particular requirements for battery supplied electronic controlgear for emergency lighting.
CEI/IEC-61347-2-7:2006 specifies particular safety requirements for d.c. supplied electronic ballasts for maintained and non-maintained emergency lighting purposes.
CEI/IEC-61347-2-7:2006 includes specific requirements for ballasts and control units for Iuminaires for emergency lighting as specified by IEC 60598-2-22.
DC supplied electronic ballasts for emergency lighting may or may not include batteries.
This standard also includes operational requirements for ballasts which, in the case of other d.c. supplied electronic ballasts, are regarded as performance requirements. This is because non-operational emergency lighting equipment presents a safety hazard.
NOTE Annex J of IEC 61347-2-3 applies to ac. supplied ballasts (normal operation) that are also suitable for emergency lighting operation from ac/dc supplies.
The formatting into separately published parts provides for ease of future amendments and revisions. Additional requirements will be added as and when a need for them is recognized. This standard is intended for ballasts for fluorescent lamps, but it is also applicable, as far as possible, to incandescent, high pressure discharge lamps and LED’s.
This standard, and the parts which make up IEC 61347-2, in referring to any of the clauses of IEC 61347-1, specify the extent to which such a clause is applicable and the order in which the tests are to be performed; they also include additional requirements, as necessary. All parts, which make up IEC 61347-2 are self-contained and, therefore, do not include reference to each other.
Where the requirements of any of the clauses of IEC 61347-1 are referred to in this standard by the phrase “The requirements of Clause n of IEC 61347-1 apply”, this phrase is interpreted as meaning that all requirements of the clause in question of Part I apply, except any which are clearly inapplicable to the specific type of lamp control gear covered by this particular part of IEC 61347-2.
