Abstract

This article displays how the photometry laboratory of the Portuguese Institute forQuality complies with the measurement traceability and method validation, the technicalrequirements 5.4 and 5.6 of the ISO/IEC 17025. After the presentation of the existingmeans and the way the metrological traceability is obtained, a short introduction to theinternal validation of the measurement method is displayed for the luminous intensity, theilluminance and the illuminance responsivity.
