This document specifies additional requirements for eye and face protectors designed to provide protection for the eyes and faces of persons against occupational hazards during welding and allied processes, such as optical radiation, impacts from flying particles and fragments, and hot solids. This document also applies to those articles of eye- and face-protection used for occupational-type tasks but not performed as part of an occupation, e.g. "do-it-yourself". This document specifies materials, design, performance requirements, and marking requirements for welding protectors which are different from and/or supplement ISO 16321-1.
