摘　　要：为了能够在出口美国的汽车灯具上刻印DOT以及SAE标识,灯具使用的光学材料必须满足FMVSS 108及SAE J576中的材料要求。其目的是为了测试材料对于自然界的风化作用的抵抗能力,所以设计了室外暴露测试,验证经受试验之后是否依然具有足够的物理和光学特性。本文将从源头出发,探究材料标准的编制目的,透光性、雾度的基本原理,透明材料及散射材料的区分,以及标准相关要求解读。最终输出材料的使用建议,帮助中国厂商顺利开拓美国市场,带领汽车产品走出去。In order to mark DOT(Department of Transportation)and SAE(Society of Automotive Engineers)Lighting Identification Code on automotive lamps exported to the United States,the materials used for optical components must meet the relevant requirements of FMVSS 108 and SAE J576.The purpose is to test the resistance of materials to weathering in nature,so outdoor exposure test is designed to determine whether the materials still have sufficient physical and optical capacities after tests.This paper starts from the source to explore the purpose of this standard and the basic principles of light transmittance and haze,distinguishes transparent materials and diffusion materials,and analyzes relevant requirements of the standard.Finally,it puts forward suggestions on the use of materials to help Chinese manufacturers successfully develop the American market and lead automotive products to go global.
