IEC 61167:2015

IEC 61167:2011 specifies the performance requirements for metal halide lamps for general lighting purposes. This second edition replaces the first edition published in 1992 and its Amendments 1 (1995), 2 (1997) and 3 (1998). This second edition constitutes a technical revision. Compared to the 1st edition, measurement methods for electrical and photometric parameters are included and safety related requirements are deleted as far as they are now covered by IEC 62035. Modern kind of ignition (e.g. aggregated pulse widths) and operation (low frequency square wave) is added with extensive description of methods of calculation for peak current ratio. At the same time, a review was made on lamps in the market which are fit for standardising, leading to a big number of new lamp data sheets in the range of 20 W up to 250 W lamp power.

IEC 61167:2018 specifies the performance requirements for metal halide lamps for general lighting purposes. This fourth edition cancels and replaces the third edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition. a) A set of new lamp data sheets has been introduced for lamp types designed for replacing high pressure sodium lamps. b) A set of new lamp data sheets has been introduced for 4 200 K versions of 3 000 K lamp types already in the standard. c) A set of new lamp data sheets has been introduced for new lamp types where high frequency ignition data is important. d) Annex G has been revised to incorporate high frequency ignition. As a consequence of this change, all data sheets in the standard have been revised to a new format. e) A new informative Annex K has been introduced, giving recommended methods of making lamp temperature measurements. The contents of the corrigendum of April 2019 have been included in this copy.
