BS EN 60676:2012

BS EN 60676:2012 specifies test procedures, conditions and methods according to which the main parameters and the main operational characteristics of electric arc furnaces (EAF) operated either with alternating current (EAFac) or with direct current (EAFdc) with acapacity above 500 kg/heat are established.

The EAF technology is also applicable to furnaces, in which liquid metal is kept at high temperature or superheated to casting temperature (e.g. in a ladle furnace (LF), operated with alternating current). Test methods for some special equipment, e.g. controlled rectifiers for EAFdc, are covered by IEC 60146-1-1.Test methods for submerged arc furnaces (SAF) are covered by IEC 60683.
