BS EN IEC 63232-1-2 Live working – Hand protective devices against the thermal hazards of an electric arc –. Part 1-2: Test methods – Method 2: Determination of arc protection class of hand protective devices by using a constrained and directed arc (box test)

Scope

This part of IEC 63232 specifies procedures to test hand protective devices for workers if there is an electric arc hazard. A directed and constrained electric arc in a test circuit is used to classify hand protective devices in four defined arc protection classes (APC).This International Standard is not dedicated toward measuring the arc rating values (ATPV[1], ELIM[2] or EBT[3]). Procedures determining these arc rating values are prescribed in IEC 63232-1-1, using an open arc for testing.The user can classify the arc protective performance into arc rating protection levels based on arc protection classes which correspond best to the different hazard and risks levels that can result from the user’s risk analysis.This standard covers the thermal effects of an electric arc. Other effects 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.Hand protective devices for work intentionally using an electric arc, e.g., arc welding, plasma torch is not covered by this standard.
