J576_198111 PLASTIC MATERIALS FOR USE IN OPTICAL PARTS SUCH AS LENSES AND REFLECTORS OF MOTOR VEHICLE LIGHTING DEVICES

This SAE Recommended Practice provides test methods and requirements to evaluate the suitability of plastic materials intended for optical applications in motor vehicles. The tests of this recommended practice are intended to determine physical and optical characteristics of the material only. Performance expectations of such a finished assembly, including its plastic components, are to be based on tests for lighting devices, as specified in SAE Standards and Recommended Practices for motor vehicle lighting equipment. Field experience has shown that plastic materials meeting the requirements of this standard and molded in accordance with good molding practices will produce durable lighting devices.
