Abstract

This approved method describes the procedures to be followed and precautions to be observed in performing reproducible luminous flux waveform measurements for use in temporal light artifact (TLA) calculations under standard conditions. This document provides a description of the method of measurement, equipment requirements, and formulation of luminous flux waveforms for use in the calculations of temporal light artifacts from light sources. Luminous flux waveforms utilized in TLA calculations are for luminous flux frequencies between 1 Hz and 3,000 Hz under various control conditions. In addition, data reporting formats are described. Intentionally flashing or signaling lights outside the defined frequency range are not included within the scope of this document.
