Overview
IEC 63078:2019 is an international standard published by the International Electrotechnical Commission (IEC) that defines test methods for induction through-heating installations used in electroheating and electromagnetic processing industries. Specifically, this standard outlines test procedures, conditions, and methods to determine the main performance parameters and operational characteristics of induction through-heating installations. It focuses on installations that heat metal billets or workpieces by induction for subsequent hot forming processes such as forging, extruding, and rolling.
Notably, IEC 63078:2019 excludes measurements solely aimed at verifying safety requirements, which are covered under related safety standards IEC 60519-1 and IEC 60519-3. It applies to low, mains, and medium frequency induction heating systems and provides additional guidance on energy efficiency assessment encompassing both electrical and processing aspects.
