About This Item
Full Description
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 estimation of the measurement uncertainty for a specific measurement task. Nevertheless, it is generally true that instruments with "better" characteristics in most cases allow smaller uncertainties than instruments with "worse" properties. This Draft 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 measurement results;
- define calibration conditions for illuminance meters and luminance meters.
