AC and/or DC-supplied electronic control gear for tubular fluorescent lamps. Performance requirements1 Scope This international Standard 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. NOTE 1 Tests in this standard are type tests. Requirements for testing individual
