Safety in electroheat installations - Part 3: Particular requirements for induction and conduction heating and induction melting installations
|Publication Date:||1 July 2005|
|ICS Code (Electric furnaces):||25.180.10|
This part of IEC 60519 is applicable to - installations for induction and conduction heating of solids, at low, mains, medium and high frequencies (for conduction heating, use of direct current is also included); - installations for induction melting, holding and superheating liquid metal at low, mains, medium and high frequencies; - those parts of the conveying or handling equipment of the electroheat installation which are within the influence of the heating section. Examples of application are: - installations for induction and conduction heating of slabs, billets, rods, strip, wire, tubes, rivets, etc. for subsequent hot forming and heat treatment; - installations with induction crucible furnaces or induction channel furnaces. This standard consists of requirements common to both induction and conduction heating installations and induction melting installations (Clauses 1 to 14) and specific requirements for induction and conduction heating installations (Annex A) and specific requirements for induction melting installations (Annex B). Significant technical changes with respect to EN 60519-3:1995 are as follows: - the latest edition of EN 60519-1 (2003), in particular the extension of the scope to cover also voltage band 3 equipment with rated voltages not exceeding 3 600 V AC or 5 000 V DC, has been taken into account; - definitions have been brought into line with the second edition of IEC 60050-841.
