Organization: CIE
Publication Date: 1 June 2014
Status: active
Page Count: 50
scope:

This CIE International Standard is applicable to illuminance and luminance meters. The Standard defines quality indices characterizing the performance of such devices in a general lighting measurement situation, as well as measurement procedures for the individual indices and standard calibration conditions.

Measurements of illuminance or luminance and their accuracy are influenced by various parameters, such as operational conditions, properties of light sources, as well as characteristics of the applied photometers. The characteristics of these photometers alone do not allow the determination of the measurement uncertainty for a specific measurement task. Nevertheless, it is generally true that instruments with "better" characteristics in most cases produce smaller uncertainties than instruments with "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 these quality indices;

• define calibration conditions for illuminance meters and luminance meters.

Where different, the definitions of the quality indices and the associated measurement procedures and methods for numerical evaluation given in this Standard supersede those given in CIE Publication 53-1982. CIE publication 69-1987 shall be superseded by this Standard.
