Installations for electroheating and electromagnetic processing - Test methods for induction through-heating installations (IEC 63078:2019)

EN-IEC 62282-8-201 defines the evaluation methods of typical performances for electricenergy storage systems using hydrogen. This is applicable to the systems that useelectrochemical reaction devices for both power charge and discharge. This document appliesto systems that are designed and used for service and operation in stationary locations (indoorand outdoor).The conceptual configurations of the electric energy storage systems using hydrogen are shownin Figure 1 and Figure 2. Figure 1 shows the system independently equipped with an electrolysermodule and a fuel cell module. Figure 2 shows the system equipped with a reversible cellmodule. There are an electrolyser, a hydrogen storage and a fuel cell, or a reversible cell, ahydrogen storage and an overall management system (which may include a pressuremanagement) as indispensable components. There may be a battery, an oxygen storage, a heatmanagement system (which may include a heat storage) and a water management system(which may include a water storage) as optional components. The performance measurement isexecuted in the area surrounded by the outside thick solid line square (system boundary).NOTE In the context of this document, the term "reversible" does not refer to the thermodynamic meaning of an idealprocess. It is common practice in the fuel cell community to call the operation mode of a cell that alternates betweenfuel cell mode and electrolysis mode "reversible".This document is intended to be used for data exchanges in commercial transactions betweenthe system manufacturers and customers. Users of this document can selectively execute testitems suitable for their purposes from those described in this document.

INSTALLATIONS FOR ELECTROHEATING AND ELECTROMAGNETIC
PROCESSING – TEST METHODS FOR INDUCTION
THROUGH-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 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.

INTRODUCTION
Induction through-heating and induction melting are very important applications of induction
heating. However, an induction through-heating installation is more complex than an induction
melting furnace, as it includes more heating manners, varieties and sizes. In addition, some
performance tests which are very useful to users, for example the determination of
temperature homogeneity of billets and energy efficiency of the installation, are not easy to
carry out.
Induction through-heating installations are widely used in many industries for example
machine building and metallurgy, for heating billets or workpieces of alloy steel, copper,
aluminum, etc. before their subsequent hot forming (e.g. forging, extruding and rolling), with
clean and fast heating, easy temperature control and automation as well as a high degree of
energy-saving.
This document was prepared on the basis of IEC 60398:2015, with some references made to
IEC 62076:2006 and “Induction Heating – Industrial Applications” published by UIE in 1992.
