SR EN IEC 60519-4:2022

This part of IEC 60519 provides particular safety requirements for arc furnace installations. This document deals with the significant hazards, hazardous situations or hazardous events relevant to industrial arc furnace installations, as listed in Annex A, for normal operation and for single fault condition as well as under conditions of reasonably foreseeable misuse. This document specifies the requirements intended to be met by the manufacturer to ensure the safety of persons and property during the complete life cycle of the equipment from design through commissioning, operation, maintenance, inspection, to decommissioning, as well as in the event of foreseeable single fault condition that can occur in the equipment. The rated voltage of arc furnace installation can be in the range of low voltage or high voltage, details are given in 4.2. This standard is applicable to arc furnace installations such as: a) furnaces for direct arc heating, forming arcs between the electrode and metal such as the electric arc furnace using alternating current (EAF AC) or direct current (EAF D
