This CIE International Standard defines quality indices characterizing the performanceof illuminance and luminance meters in a general lighting measurement situation, aswell as measurement procedures for the individual indices and standard calibrationconditions.Measurements of illuminance or luminance and their accuracy are influenced byvarious parameters, such as operational conditions, properties of light sources, aswell as characteristics of the applied photometers. The characteristics of thesephotometers alone do not allow the determination of the measurement uncertainty fora specific measurement task. Nevertheless, it is generally true that instruments with"better" characteristics in most cases produce smaller uncertainties than instrumentswith "worse" properties. This Standard has been written to:
- give clear and unambiguous definitions for the individual quality indices;
- define measurement procedures and methods for numerical evaluation of thesequality indices;
- define calibration conditions for illuminance meters and luminance meters.
