标准摘要
[中文适用范围]： 本文件提供了表征防晒霜产品的防晒系数（SPF）、UVA保护系数（UVA-PF）和临界波长（CW）保护的方法，无需要求生物学反应。测试方法适用于乳液和单一相产品。该方法尚未评估用于粉末状防晒霜产品。本文件给出了规定，以确定防晒霜产品在皮肤上的绝对光谱吸收特性，以估计晒伤和UVA保护。它适用于含有任何能够吸收、反射或散射紫外线（UV）的成分的产品，并且意图与人体皮肤接触。 [外文原描述]： This document provides a procedure to characterize the sun protection factor (SPF), UVA protection factor (UVA-PF) and critical wavelength (CW) protection of sunscreen products without requiring biological responses. The test method is applicable for emulsions and single-phase products. The method has not been evaluated for use with powder forms sunscreen products. This document gives specifications to enable determination of the absolute spectral absorbance characteristics of a sunscreen product on skin to estimate sunburn and UVA protection. It is applicable to products that contain any component able to absorb, reflect or scatter ultraviolet (UV) rays and which are intended to be placed in contact with human skin.
