SAE J2009_202208

This SAE Recommended Practice applies to motor vehicle forward illumination systems and subsystems generated by discharge sources. It provides test methods, requirements, and guidelines applicable to the special characteristics of gaseous discharge lighting devices which supplement those required for forward illumination systems using incandescent light sources. The document is applicable to both discharge forward lighting systems, subsystems and components. This document is intended to be a guide to standard practice and is subject to change to reflect additional experience and technical advances. The following updates have been incorporated in SAE J2009: 2.1.1: Updated title for SAE J578. 2.1.2: Removed ANSI C78.376-1969. 2.1.4: Added UN R.E.5. 2.1.3, 2.1.4, 2.1.5, 2.1.6, 2.1.7: Updated applicable document reference locations. 2.2.1, 2.2.4, 2.2.5: Updated related publication reference locations. 3.1: Revised to “An automotive road illumination system comprising of one or more headlamps, discharge light sources, ballast/starting system, and interconnecting wiring.” 3.8: Revised to “A quantitative measure of the color appearance of objects under a given light source in comparison with their color appearance under a reference or standard illuminant.” 3.11: Revised to “Ballast (Automotive Ballast).” Table 1: Added additional designation R.E.5 to footnote (a). 7.3: Removed “[Current fluorescent lamp chromaticity standards in the United States are now based on spectroradiometrically determined assignments by the National Institute of Standards and Technology. Refer to ANSI C78.376-1969.].”
