IEC 60929 Ed. 4.0 b:2011

IEC 60929:2011 specifies performance requirements for electronic control gear for use on a.c. at 50 Hz or 60 Hz and/or d.c. supplies, both up to 1 000 V, with operating frequencies deviating from the supply frequency, associated with fluorescent lamps as specified in IEC 60081 and IEC 60901, and other fluorescent lamps for high-frequency operation. This fourth edition cancels and replaces the third edition published in 2006 and constitutes a technical revision. The essential change with respect to the third edition is the extension to DC supplied control gear and the deletion of the requirements for digital signal control of electronic control gear.
