Product Code:SAE J1647
Title:Plastic Materials and Coatings for Use In or On Optical Parts Such as Lenses and Reflectors of High-Intensity Discharge Forward Lighting Devices Used in Motor Vehicles
Issuing Committee:Lighting Materials Standards Committee
Scope:This SAE Recommended Practice provides test methods and requirements to evaluate the suitability of plastic optical materials for possible use in discharge forward lighting (DFL) devices in motor vehicles. These materials are typically used for lenses and reflectors. Separate testing is required for each combination of material, industrial coating, DFL light source, and device focal length. The tests are intended to determine physical and optical characteristics of the materials and coatings. Performance expectations of finished assemblies, including plastic components, are to be based on tests for lighting devices, as specified in SAE Standards and Recommended Practices for motor vehicle lighting equipment. Optical components exposed to weathering should also be subject to SAE J576.
