本文件规定了测定个人眼睛和面部保护器物理光学特性的参考试验方法。本文件不适用于要求标准规定了其他试验方法的任何眼睛和面部防护产品。如果其他试验方法被证明是等效的，并且包括不大于参考方法要求的测量不确定度，则可以使用其他试验方法。

This document specifies the reference test methods for determining the physical optical properties of personal eye and face protectors. This document does not apply to any eye and face protection products for which the requirements standard(s) specifies other test methods. Other test methods can be used provided they have been shown to be equivalent and include uncertainties of measurement no greater than those required of the reference method.
