Lamp controlgear - Part 2-9: Particular requirements for ballasts for discharge lamps (excluding fluorescent lamps)

This part of EN 61347 specifies particular 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. The standard covers inductive-type ballasts for use on a.c. supplies up to 1 000 V at 50 Hz or 60 Hz, associated with discharge lamps, having rated wattages, dimensions and characteristics as specified in EN 60188, EN 60192 and EN 60662. This first edition of EN 61347-2-9, together with EN 61347-1, cancels and replaces the second edition of EN 60922, published in 1997, and constitutes a minor revision. This standard shall be used in conjunction with EN 61347-1. It was established on the basis of the first edition (2000) of that standard.
