SAFETY IN ELECTROHEAT INSTALLATIONS –

Part 11: Particular requirements for installations using the effect of
electromagnetic forces on liquid metals

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 60519-11 has been prepared by IEC technical committee 27:
Industrial electroheating equipment.
This second edition cancels and replaces the first edition published in 1997 and constitutes a
technical revision. The significant changes with respect to the previous edition are as follows:
• the latest editions of IEC 60519-1:2003 and IEC 60519-3:2005 have been taken into
account;
• definitions have been brought into line with the second edition of IEC 60050-841:2004.
This standard is to be used in conjunction with IEC 60519-1:2003. It is intended to specify
particular requirements for installations using the effect of electromagnetic forces on liquid
metals.

FDIS Report on voting
27/577/FDIS 27/585/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.
The list of all parts of the IEC 60519 series, under the general title Safety in electroheat
installations, can be found on the IEC website.
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,

SAFETY IN ELECTROHEAT INSTALLATIONS –

Part 11: Particular requirements for installations using the effect of
electromagnetic forces on liquid metals

1 Scope
This part of IEC 60519 applies to installations predominantly using the effect of
electromagnetic forces on liquid metals:
− installations for electromagnetic (induction) stirring or transport of liquid metals at low
frequencies;
− installations that influence the pouring process by an electromagnetic field;
− parts directly affected by the electromagnetic stirring, transport or pouring installation.
Examples of application:
− stirring devices for casting machines, arc furnaces, ladles, etc.;
− transport of liquid metal for emptying or filling furnaces, launders or moulds;
− devices to transport liquid metal with simultaneous proportioning of the transported
quantity, for example, for filling diecasting machines;
− influencing the ingot surface or the pouring stream enhancing crystallization by means of
an electromagnetic field during continuous casting;
− sealing of mechanical gaps of melt vessels, for example, in vertical galvanizing line.
