SAFETY IN ELECTROHEAT INSTALLATIONS –

Part 9: Particular requirements for high-frequency
dielectric heating installations


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 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 60519-9 has been prepared by IEC technical committee 27:
Industrial electroheating equipment.
IEC 60519-9 is to be used in conjunction with the third edition of IEC 60519-1. It is intended to
specify particular requirements for high-frequency dielectric heating installations.
This second edition cancels and replaces the first edition published in 1987 and constitutes a
technical revision. The significant changes with respect to the previous edition are as follows:
– requirements for the protection against direct contact have been revised;
– the structure has been adjusted to the latest ISO/IEC Directives, in particular the scope,
object and introduction of normative references;

---------------------- Page: 7 ----------------------

– the third edition of IEC 60519-1 has been taken into account;
– definitions have been brought into line with the second edition of IEC 60050-841.
The text of this standard is based on the following documents:
FDIS Report on voting
27/473/FDIS 27/493/RVD

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
IEC 60519 consists of the following parts, under the general title Safety in electroheat
installations:
Part 1: General requirements
Part 2: Particular requirements for resistance heating equipment
Part 3: Particular requirements for induction and conduction heating and induction melting
installations
Part 4: Particular requirements for arc furnace installations
Part 5: Specifications for safety in plasma installations
Part 6: Specifications for safety in industrial microwave heating equipment
Part 7: Particular requirements for installations with electron guns
Part 8: Particular requirements for electroslag remelting furnaces
Part 9: Particular requirements for high-frequency dielectric heating installations
Part 10: Particular requirements for electrical resistance trace heating systems for industrial
and commercial applications
Part 11: Particular requirements for installations for electromagnetic stirring, transport or
pouring of metal liquids
Part 21: Particular requirements for resistance heating equipment – Heating and melting
glass equipment
NOTE If necessary, additional parts covering particular industrial electroheat equipment may be prepared.
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in
the data related to the specific publication. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

SAFETY IN ELECTROHEAT INSTALLATIONS –

Part 9: Particular requirements for high-frequency
dielectric heating installations



1 Scope and object
This part of IEC 60519 is applicable to industrial high-frequency dielectric heating installations
for the purpose of thermal applications such as melting, drying, welding, insect extermination
and gluing of partially or non-conductive materials such as plastics, wood, rubber, textiles,
glass, ceramic, paper, bamboo, foodstuffs, etc. in both normal and protective atmospheres,
using for example inert gases or vacuum.
This standard relates to high-frequency dielectric heating installations with nominal frequency
in the range from 1 MHz to 300 MHz with rated useful output power greater than 50 W.
NOTE In accordance with CISPR 11, there are preferred frequencies designated by the International
Telecommunication Union for use as fundamental ISM frequencies.
The voltage band according to IEC 60519-1 relates to the mains supply voltage. In some
circuits of the dielectric heating installation, the d.c., a.c. or radio-frequency voltages can
have greater values (e.g. in the generator due to a built-in transformer).
