Anotace textu normy ČSN EN IEC 60676-ed.3 (361120):

This document specifies the basic test procedures, conditions and methods for establishing the main performance parameters and the main operational characteristics of furnaces for direct arc heating, forming arcs between the electrode and metal, such as electric arc furnaces using alternating current (EAF AC) or direct current (EAF DC), and ladle furnaces (LF), with rated power level above 500 kVA .

Measurements and tests that are solely used for the verification of safety requirements of equipment for direct electrical arc furnaces are outside the scope of this document and are covered by IEC 60519-1, IEC 60519-4 and ISO 13578.

This document is applicable for the commissioning, verification of design improvements or for energy related tasks with respect to energy use or energy efficiency, establishing of an energy baseline, and labelling. Some concepts from this document can directly be used as key performance indicators.

Detailed tests for specific types of electric arc furnace equipment and installations are beyond the scope of this document. This document is intended as general reference for all future test standards applicable to particular electric arc furnace equipment or installations.

This document includes the concept and material presented in IEC 60398 on energy efficiency dealing with the electrical and processing parts of the equipment, as well as the overall performance.

Test methods for some special equipment, e.g., semiconductor converters, are covered by IEC 60146-1-1 and furnace transformers are covered by IEC 60076 series
