IEC 61482-1-2:2014 PDF

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 these arc rating values are prescribed in IEC 61482-1-1@ using an open arc for testing. Other effects than the thermal effects of an electric arc like noise@ light emissions@ pressure rise@ hot oil@ electric shock@ the consequences of physical and mental shock or toxic influences are not covered by this standard. Protective clothing for work intentionally using an electric arc@ e.g. arc welding@ plasma torch@ is not covered by this standard.
