标准摘要
[中文适用范围]： 本文件规定了确定个人眼部和面部保护器物理光学特性的参考测试方法。 本文件不适用于要求标准指定其他测试方法的任何眼部和面部防护产品。 可以使用其他测试方法，只要它们已被证明是等效的，并且测量的不确定度不大于参考方法所需的测量不确定度。 [外文原描述]： 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.
