Rationale: At this time we would like to reaffirm J1330 in its current revision. A full rewrite is being prepared by the task force at this time to include many new technologies and measurement techniques to improve the measurement accuracy of photometric laboratories. Many of the topics are going to be discussed with general terms, and also specific examples of various industries, so that more than one industry can use this standard. This includes at this time both the automotive and aerospace aircraft lighting industries. Some changes included will be: a Measurement of PWM (Pulse Width Modulated) and other modulated sources. b Measurement of Chromaticity, UV Content, Red (and other color) Content, retro-reflex color. c Measurement of Low Light Level sources, including Low-light Visibility. d Added to “Related Publications” SAE J2382 as a method of high-speed photometric measurement that references this document. e Measurement of Luminance, including License Plate Lamps and other luminance measurements. f Measurement of Flashing Light sources. g Measurement of Total Luminous Flux using an Integrating Sphere. h Added references to IESNA documents
