标准摘要
[中文适用范围]： 本 SAE 推荐实践提供了测试方法和要求，以评估塑料光学材料在机动车辆放电前照灯 (DFL) 装置中可能使用的适用性。这些材料通常用于透镜和反射器。材料@工业涂层@DFL光源@和设备焦距的每种组合都需要单独测试。这些测试旨在确定材料和涂层的物理和光学特性。包括塑料部件@在内的成品组件@的性能预期应基于机动车辆照明设备的SAE标准和推荐实践中规定的照明设备@测试。暴露于风化的光学元件也应符合 SAE J576 的要求。 [外文原描述]： 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 StandardDetails and Recommended Practices for motor vehicle lighting equipment. Optical components exposed to weathering should also be subject to SAE J576.Cross Reference: ASTMD1003,ASTME308,CIE1931,J2009_201608,J576_201708,J578_201603
