|Publication Date:||1 January 1998|
This standard specifies safety requirements for ballasts for discharge lamps such as high-pressure mercury vapour, low-pressure sodium vapour, high-pressure sodium vapour and metal halide lamps. Section One specifies general requirements and Section Two specifies thermal and mechanical requirements. The standard covers inductive-type ballasts for use on a.c. supplies up to 1000 V at 50 Hz or 60 Hz associated with discharge lamps, having rated wattages, dimensions and characteristics as specified in the relevant I E C lamp standards according to I E C Publications 188, 192 and 662.
Tests in this standard are type tests. Requirements for testing individual ballasts during production are not included.
Notes 1. - For certain types of discharge lamp an ignitor is required.
2. - Ballasts for tubular fluorescent discharge lamps are covered by I EC Publication 920.
