This draft of a new edition of the International Lighting Vocabulary (ILV) is the result of intensive work carried out by CIE JTC 8 in order to harmonize the content of the ILV in its version of 2011 (published as CIE S 017:2011) with the content of the International Electrotechnical Vocabulary (IEV), subject area “Lighting” (IEC 60050-845), considering the rules for drafting definitions as given in the ISO/IEC Directives. In addition parallel work in ISO/TC 12/WG 19 (Revision ISO 80000, all parts) was considered in the harmonization process.[more]
