本SAE性能标准的范围是提供一种简单、实用且广泛适用的试验程序，用于评估道路车辆反光安全玻璃材料的发光光源和反射率。本SAE性能标准提供了一个在光学领域广泛使用的简单测试程序，可用于测量道路车辆安全玻璃材料所用薄膜的反射率。本试验程序适用于可行性而非测量精度最为重要的条件。当必须测试嵌装玻璃而不是小试样时，可以在实验室外的质量控制环境和类似应用中进行测量。

The scope of this SAE performance standard is to provide a simple, practical, and broadly applicable test procedure for appraising luminous Illuminant A reflectance of reflecting safety glazing materials for road vehicles.This SAE performance standard, which provides a simple test procedure widely used in the optics field, may be used to measure the reflectivity which films applied to safety glazing materials for road vehicles may enhance. This test procedure applies to conditions where feasibility, rather than accuracy of measurement, is of prime importance. Measurements can be made outside laboratories in a quality control environment and in similar applications, when glazings, instead of small test specimens, have to be tested.
