This document specifies additional material, design, performance and marking requirements for eye and face protectors designed to provide protection for the eyes and faces of persons against occupational hazards during welding and related techniques, such as optical radiation, impacts from flying particles and fragments, and hot solids. The other applicable requirements for welding protectors are given in ISO 16321-1. This document also applies to those products of eye and face protection used for occupational-type tasks but not performed as part of an occupation, e.g. "do-it-yourself".
