IEC 61347-2-9:2000+A1:2003+A2:2009 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 IEC 60188, IEC 60192 and IEC 60662. This standard shall be used in conjunction with IEC 61347-1. It was established on the basis of the first edition (2000) of that standard. This consolidated version consists of the first edition (2000), its amendment 1 (2003) and its amendment 2 (2006). Therefore, no need to order amendments in addition to this publication. This publication shall be read in conjunction with IEC 61347-1:2000.
