Foreword
The text of document 27/704/CDV, future edition 3 of IEC 60519-6, prepared by IEC TC 27, Industrial
electroheating, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as
EN 60519-6 on 2011-03-03.
This European Standard supersedes EN 60519-6:2002.
The significant changes with respect to EN 60519-6:2002 are as follows:
– the third edition of EN 60519-1:2003 has been taken into account (the structure of clauses was
adapted to it as far as practicable);
– some definitions are modified or brought into line with IEC 60050-841:2004;
– clauses on abnormal operation, access openings, microwave enclosure and barriers are added;
– the microwave leakage measurements are in a normative Annex A;
– an informative Annex B on the rationales for microwave exposure and leakage limits is added;
– Bibliography is added.
This part of EN 60519 is to be used in conjunction with EN 60519-1:2003. It is intended to specify
particular requirements for industrial microwave heating equipment. This Part 6 supplements or modifies
the corresponding clauses of EN 60519-1, so as to convert it into an EN standard. Where a particular
sub-clause of Part 1 is not mentioned in this Part 6, that sub-clause applies as far as is reasonable.
Where this standard states "addition", modification" or "replacement", the relevant text of Part 1 is to be
adapted accordingly.
NOTE Sub-clauses and notes which are additional to those in Part 2 are numbered starting from 101, additional
items and annexes are lettered aa, bb or AA, BB, etc.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2011-12-03
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2014-03-03
Annex ZA has been added by CENELEC.

Endorsement notice
The text of the International Standard IEC 60519-6:2011 was approved by CENELEC as a European
Standard without any modification.

SAFETY IN ELECTROHEAT INSTALLATIONS –

Part 6: Specifications for safety in industrial
microwave heating equipment
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 publicati
