This report CIE 121:1996 covers general requirements for the photometry of luminaires which are considered to be applicable to most types of luminaire.
The report CIE 121:1996 sets out to provide specifications for the standard conditions under which photometric tests should be carried out and to recommend testing procedures which will give sufficiently accurate and reproducible resuits when determining and reporting the photometric characteristics of luminaires. These specifications are intended to provide a basis for uniform national standards and to give guidance to photometric laboratories in the conduct of tests and in the presentation of luminaire performance data. The report also gives specifications for the measurement of correction factors applicable to luminaires operated under practical test conditions different from the standard test conditions.
