scope:
This document provides the method for measurement of luminous flux and color maintenance of LED lamps, integrated; LED lamps, non-integrated; LED light engines, and LED luminaires. The method describes the procedures to be followed and the precautions to be observed in obtaining and reproducing luminous flux and color maintenance measurements under standard operating conditions.
This approved method does not provide guidance or recommendations regarding sampling, predictive estimations or extrapolation of luminous flux maintenance beyond the final measurement.
