Bibliography

IEC 61347-2-9:2012 series specifies particular safety requirements for electromagnetic controlgear 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 electromagnetic controlgear 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 IEC 60188, IEC 60192 and IEC 60662. This second edition cancels and replaces the first edition published in 2000, Amendment 1:2003 and Amendment 2:2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) the addition of a new Clause 14;
b) the word "ballast" is changed to "electromagnetic controlgear".

This publication is to be read in conjunction with IEC 61347-1:2007.
