本标准旨在向消费者提供有关防护太阳紫外线辐射（UVR）的材料和衣物相对性能的信息。该信息以标签方案的形式提供给消费者，标签方案基于客观、可重复的测试方法。它适用于所有要求紫外线防护系数（UPF）等级的材料和衣物。合成遮光布、防晒霜、太阳镜和护目镜提供的防晒是其他标准的主题。

This Standard is intended to provide information to the consumer on the relative capability of materials and items of clothing to provide protection against solar ultraviolet radiation (UVR). This information is provided to the consumer in the form of a labelling scheme based on an objective, reproducible test method. It is applicable to all materials and clothing items seeking to claim an Ultraviolet Protection Factor (UPF) rating. Sun-protection offered by synthetic shade cloth, sunscreens, sunglasses and eye protectors is the subject of other Standards.
