scope:

This part of IEC 61 347 specifies general and safety requirements for miscellaneous electronic circuits used with luminaires for use on a.c. supplies up to 1 O00 V at 50 Hz or 60 H t and/or d.c. supplies up to 250 V. This part does not apply to circuits or devices for which specific IEC standards are published.

NOTE  Examples of miscellaneous electronic circuits used with luminaires are

 - electronic ballast control circuits;

 - switching circuits used in association with daylight andlor presence sensors;

 - circuits to assist EMC performance;

 - intermittence and similar devices used with lighting chains:

 - earth leakage or open-circuit protective devices used with neon transformers.
