This technical report provides general requirements for the photometry of luminaires of most types and includes the following information:
• standard test conditions under which the tests should be carried out, with acceptable practical tolerances;
• selection procedures for lamps and luminaires;
• procedures for measurement of the photometric characteristics of luminaires and assessment of the possible sources of error;
• correction factors and service conversion factors;
• presentation of test results.
The report is considered to be sufficiently comprehensive to form a practical guide for industrial laboratories and contains sufficient information to replace publication CIE 24-1973 “Photometry of indoor type luminaires” and CIE 27-1973 “Photometry of luminaires for street lighting”. CIE will publish supplementary reports covering these types of luminaires more specifically.
