Scope

This standard shall be read in conjunction with IEC Publication 519-1. It consists of a general section covering requirements common to both induction and conduction heating installations and induction melting installations and two sections - A and B - giving specific requirements for each type of installation. The standard applies to: a) Installations for induction and conduction heating of solids at low, medium and high frequencies - For conduction heating use of direct current is also included * b) Installations for induction melting, holding and superheating at low, medium and high frequencies * c) Those parts of the conveying or handling equipment of the electroheat installation which are within the influence of the heating section. Examples of application: Installations for induction and conduction heating of slabs, billets, rods, strips, wire, tubes, rivets, etc., for subsequent hot forming and heat treatment - Installations with induction crucible furnaces or induction channel furnaces
