SAFETY IN ELECTROHEATING 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,
Publicly Available Specifications (PAS) 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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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.
This fourth edition cancels and replaces the third edition published in 2003. It constitutes
a technical revision.
The main technical changes with respect to the previous edition are as follows:

SAFETY IN ELECTROHEATING INSTALLATIONS –

Part 1: General requirements



1 Scope and object
This part of IEC 60519 specifies the general safety requirements applicable to industrial
electroheating installations.
In case these requirements differ from those of other IEC publications, an equivalent
degree of safety is ensured.
The requirements apply to industrial installations, intended for electroheating and
electroheat based treatment technologies, with the possible use of the following equipment:
– equipment for direct and indirect resistance heating;
– equipment for electric resistance trace heating;
– equipment for induction heating;
– equipment using the effect of EM forces on liquid metals;
– equipment for arc heating, including submerged arc heating;
– equipment for electroslag remelting;
– equipment for plasma heating;
– equipment for microwave heating;
– equipment for dielectric heating;
– equipment for electron beam heating;
– equipment for laser heating;
– equipment for infrared radiation heating.
NOTE 1 The list presents typical examples of equipment used in installations covered by this standard and is not
exhaustive.
This standard is not applicable for heating appliances for household (e.g. electric cooking),
laboratory or medical applications or for welding equipment, if covered by other particular
standards, nor does it apply to any kind of space heating.
This standard refers to normal operation of industrial electroheating installations. It is
intended to ensure the safety of persons also in the case of abnormal operation and when
faults occur in electroheating installations. This standard presumes that the installations are
operated and maintained only by personnel consisting of instructed or skilled persons,
respectively.
The object of this standard is to specify the general safety requirements for electroheating
installations. These safety requirements concern the protection of persons and the
environment against dangers of electrical origin and also against certain dangers of non-
electrical origin, common to all types of equipment and installations.
Certain clauses of this standard concern not only safety of personnel but also protection of
the environment.
The overall safety requirements result from the joint application of the general requirements
specified in this standard and Particular Requirements concerning the specific industrial

---------------------- Page: 13 ----------------------

application of electroheat. These Particular Requirements supplement, modify or replace
the general requirements.
The Particular Requirements cover particular safety relevant features such as high voltages
and electric fields or high currents and magnetic fields, also with respect to the frequencies.
NOTE 2 Information on non-electrical hazards possibly arising from the utilization of industrial electroheating
equipment may also be taken from European Standard EN 746-1 (see Bibliography), which specifies common safety
requirements for industrial thermoprocessing equipment.
General test methods for industrial electroheating installations are specified in IEC 60398.
