1 Scope This document is applicable to eye, face and head protector s used in work where there is a risk of exposure to an electric arc hazard. Such protector s consist of one or several devices (e.g. hood , goggle s, balaclava s, face shields , helmet s, etc.), which might need to be combined together in order to give protection to eye, face and head for the intended use. This document covers the performance requirements for protector s and single protective devices considering thermal, optical and mechanical hazards of an electric arc . Because of the limitations of test apparatus at very high energy arcs, no arc rating above 4 100 kJ/m 2 (100 cal/cm 2 ) can be assigned to protector s. This document does not cover protection against electric shock, noise, the consequences of physical and mental shock and the toxic influences caused by an electric arc . This document does not cover protector s for work intentionally using an electric arc , e.g. arc welding, plasma torch. This document does not cover face-screens for the reduction of an electric field inside conductive clothing in accord...
