SAFETY IN ELECTROHEAT INSTALLATIONS –
Part 1: General requirements
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to
technical committees; any IEC National Committee interested in the subject dealt with may participate in this
preparatory work. International, governmental and non-governmental organizations liaising with the IEC also
participate in this preparation. IEC collaborates closely with the International Organization for Standardization
(ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60519-1 has been prepared by IEC technical committee 27:
Industrial electroheating equipment.
This third edition cancels and replaces the second edition published in 1984. It constitutes
a technical revision.
In this third edition of IEC 60519-1 significant technical changes with respect to the previous
edition are as follows:
– the scope is now extended to cover also voltage band 3 equipment with rated voltage not
exceeding 3 600 V a.c. or 5 000 V d.c.; the relevant provisions for such equipment have
been added in clauses on, for example protection against electric shock, equipotential
bonding or maintenance work;
– requirements concerning equipotential bonding have been essentially modified and
introduced in a separate clause, based on the actual relevant provisions of IEC 60204-1;
– general provisions on the impact of electromagnetic effects have been given;
– information concerning technical documentation has been modified;
– a bibliography has been added.

equivalent degree of safety shall be ensured.
The present requirements apply to industrial electroheat and associated treatment installations
such as:
– direct arc furnaces;
– submerged arc furnaces;
– equipment for arc heating (other than arc furnaces);
– electroslag remelting furnaces;
– plasma equipment;
– induction melting furnaces;
– equipment for induction heating;

1.2 Object
The requirements for the safety of persons in electroheat installations are the subject, on the
one hand, of general requirements applicable to electroheat installations as a whole and, on
the other hand, of particular requirements applicable to each of them. This standard gives only
general requirements.
These safety requirements concern the protection of persons against dangers of particularly
electrical origin and also against certain dangers of non-electrical origin.
The safety requirements to be observed result from the joint application of general
requirements and particular requirements concerning the specific industrial application of the
electroheat. Where particular requirements exist they shall complete, modify or replace the
general requirements. In the absence of particular requirements, the requirements to be
complied with are those, which are specified in this standard.
In addition, for electroheat installations of voltage bands 1 and 2 and frequencies of up to
60 Hz, the following parts of IEC 60364 shall apply: IEC 60364-1, IEC 60364-4-41, IEC 60364-
4-42, IEC 60364-4-43, IEC 60364-5-53, IEC 60364-5-54.
For voltage band 3, electroheat equipment with rated voltage not exceeding 3 600 V a.c. or
5 000 V d.c., special requirements shall be complied with. Such requirements are specified in
this standard. For rated voltage exceeding 3 600 V a.c. or 5 000 V d.c., additional
specifications are under consideration.
In addition, for electrical equipment of up to 1 000 V a.c. or 1 500 V d.c. and frequencies of up
to 200 Hz, IEC 60204-1 may be taken as a guidance. IEC 60204-1 however does not cover
