La CEI 60683:2011 spécifie les procédures, les conditions et les méthodes d'essai selon lesquelles les paramètres principaux et les caractéristiques de fonctionnement principales des fours à arc submergé dont les niveaux de puissance électrique assignée sont supérieurs à 500 kVA sont établis. La présente norme est applicable aux fours à arc submergé à une ou plusieurs électrodes. Afin de déterminer d'autres évaluations techniques ou économiques, des essais supplémentaires peuvent être nécessaires. Les essais pour des équipements spéciaux des fours commandés par convertisseur à semiconducteurs, tels que les redresseurs commandés ou les convertisseurs à courant alternatif commandés, sont couverts par la CEI 60146-1-1. Cette deuxième édition annule et remplace l'édition précédente parue en 1980, dont elle constitue une révision technique.

Overview

EN 60683:2012 (IEC 60683:2011 adopted by CLC/CENELEC) defines standardized test methods for submerged-arc furnaces (SAF) used in industrial electroheating. The standard applies to SAF installations with rated electrical power above 500 kVA and to furnaces with one or more electrodes. Its purpose is to specify test procedures, conditions and measurement methods to establish the main electrical and operational parameters and characteristics of an SAF. For converter-controlled equipment (controlled rectifiers / a.c. converters) see IEC 60146-1-1.

Key Topics

  • Scope and applicability: SAFs > 500 kVA; single- or multi-electrode configurations; establishes how to determine principal performance parameters.
  • Features of the SAF system: tests for high-voltage / high-current electrical assemblies, electrode systems, transformer arrangements and water cooling circuits.
  • Tests and general conditions: procedures for cold tests (pre-commissioning checks) and hot commissioning tests under operational conditions.
  • Technical tests:
    • Electrical insulation resistance checks during erection, cold state and hot state.
    • Cooling water system verification and leak/performance checks.
    • Electrode regulation characteristics: motion speed, dead band, response time and control behavior.
    • Electrical characteristics during operation: measurement of active/apparent power, currents, and secondary voltage from the furnace transformer.
    • Operational parameters: monitoring furnace losses, high-current lines and other operational metrics.
  • Terms and definitions: aligned with IEC vocabularies (e.g., active/apparent power, electrode types, furnace transformer).

Applications

EN 60683:2012 is practical for:

  • Manufacturers of submerged-arc furnaces to validate design and performance.
  • Plant engineers and commissioning teams conducting cold and hot commissioning tests.
  • Testing laboratories and inspection bodies performing acceptance tests and compliance verification.
  • Procurement and asset owners assessing technical and operational characteristics for purchase or lifecycle evaluation.
  • Safety and standards compliance teams ensuring installations meet recognized test procedures for reliable operation.

Using EN 60683 helps standardize test results, supports safer commissioning of SAF installations, and provides a baseline for technical or economic assessments (with the note that additional tests may be required for detailed evaluations).

TEST METHODS FOR SUBMERGED-ARC FURNACES

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 60683 has been prepared by IEC technical committee 27:
Industrial electroheating.
This second edition cancels and replaces the previous edition published in 1980 and
constitutes a technical revision.
Significant technical changes with respect to the previous edition are as follows:
– Clause 1 (Scope and object) – the types of furnaces covered by this standard are more
clearly defined.
– Clause 2 (Normative references) and Clause 3 (Terms and definitions) have been
updated and completed.
– A new Clause 4 (Features of the SAF sytem) has been added; it mainly concentrates
on the tests necessary for high voltage/high current electrical equipment in the
installation.
– Clause 5 (Tests and general conditions) and Clause 6 (Technical tests) have been
modified according to today's requirements for safe operation of a SAF.
