Installations for electroheating and electromagnetic processing - General performance test methods

This International Standard specifies the basic test procedures, conditions and methods for
establishing the main performance parameters and the main operational characteristics of
industrial installations and equipment intended for electroheating (EH) or electromagnetic
processing of materials (EPM).
Measurements and tests that are solely used for the verification of safety requirements of
equipment for EH or for EPM are outside the scope of this standard and are covered by the
IEC 60519 series.
This standard is applicable for the commissioning, verification of design improvements or for
energy related tasks including benchmarking with respect to energy use or energy efficiency,
establishing of an energy baseline, and labelling. Some concepts from this standard can
directly be used as key performance indicators.
Detailed tests for specific types of EH or EPM equipment and installations are beyond the
scope of this standard and are provided in particular test standards for EH or EPM equipment.
This standard is intended as general reference for all future test standards applicable to
particular EH or EPM equipment or installations.
This standard includes the concept and material presented in IEC TS 62796 on energy
efficiency dealing with the electrical and processing parts of the equipment, as well as the
overall performance.

GENERAL PERFORMANCE TEST METHODS
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 60398 has been prepared by IEC technical committee 27: Industrial electroheating and electromagnetic processing. This third edition cancels and replaces the second edition of IEC 60398 published in 1999 and the first edition of IEC TS 62796 published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: • the title and scope of the standard have been expanded to include installations and equipment for electromagnetic processing of materials; • the requirements have been restructured; SIST EN 60398:2015

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 committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data related to the specific publication.

– 6 – IEC 60398:2015  IEC 2015 INTRODUCTION Designing equipment for electroheating (EH) or for electromagnetic processing of materials (EPM) is a complex task. The manufacturer of the installation or equipment usually needs to fulfil the following requirements, which come from different sources and are quite often in this order of priorities: a) to enable the intended process and make the installation to work properly; b) to be cost effective during design and manufacturing; c) to ensure that the equipment is safe to use in the sense of providing freedom from unacceptable risk of physical injury or damage to the health of the operator (safety in the narrower sense of ISO 12100:2010); d) to prove that the equipment is cost effective to operate and uses sufficiently small amounts of energy, material and other resources; e) to ensure that the equipment is safe to use in the sense of providing freedom from unacceptable risk or physical injury or damage to the health of people, or damage to property or the environment (adding other safety aims to c) and in the much broader definition of safety according to ISO/IEC Guide 51). It is usually part of the proprietary knowledge of the manufacturer or user of the equipment, to make it cost effective or enabling intended processes with a benefit. IEC 60519-1:— assists with achieving safety in the ISO 12100:2010 sense. The focus of this standard is on basic requirements for measuring instrumentation and test methods concerned with energy and resource efficiency, performance of the intended process and assessing cost of ownership for installations and equipment for EH and EPM.
