ISO/CIE 19476:2014
Characterization of the performance of illuminance meters and luminance meters
Product Details
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.
