Live working. Protective clothing against the thermal hazards of an electric arc - Test methods. Method 2: Determination of arc protection class of material and clothing by using a constrained and directed arc (box test) Ingestion-build-109673 Who is BS EN 2591-4201 Scope This part of IEC 61482 specifies procedures to test material and garments intended for use in heat and flame resistant clothing for workers if there is an electric arc hazard. A directed and constrained electric arc in a test circuit is used to classify material and clothing in two defined arc protection classes. This International Standard is not dedicated toward measuring the arc rating values (ATPV1, ELIM2 or EBT3). Procedures determining
