Safety in installations for electroheating and electromagnetic processing - Part 4: Particular requirements for arc furnace installations (IEC 60519-4:2021)

This part of IEC 60519 provides particular safety requirements for arc furnace installations. This
document deals with the significant hazards, hazardous situations or hazardous events relevant
to industrial arc furnace installations, as listed in Annex A, for normal operation and for single
fault condition as well as under conditions of reasonably foreseeable misuse.
This document specifies the requirements intended to be met by the manufacturer to ensure
the safety of persons and property during the complete life cycle of the equipment from design
through commissioning, operation, maintenance, inspection, to decommissioning, as well as in
the event of foreseeable single fault condition that can occur in the equipment.
The rated voltage of arc furnace installation can be in the range of low voltage or high voltage,
details are given in 4.2.
This standard is applicable to arc furnace installations such as:
a) furnaces for direct arc heating, forming arcs between the electrode and metal such as the
electric arc furnace using alternating current (EAF AC) or direct current (EAF DC), and the
ladle furnace (LF);
b) furnaces for arc-resistance heating forming arcs between the electrode and the charge
material or heating the charge material by the Joule effect, such as the submerged arcresistance furnace using alternating current (SAF AC), or direct current (SAF DC).
NOTE 1 In some documents, the terms "smelter" or "electrical reduction furnace" are used.
Furnace installation for unattended operation is not covered by this document.
This document does not provide requirements for type testing.
NOTE 2 Industrial equipment covered by this document is typically produced as a single unit or a very small number
of units; such unit usually has a very high value and can cause severe harm at disintegration.
This document does not address data security and hazards arising from neglect of security.
With respect to noise of electrical an arc furnace, ISO 13578:2017, 6.1.23 applies.
EAF DC and SAF DC are classified as zero frequency (0 Hz) equipment types. EAF AC, SAF
AC and LF are classified as mains frequency (50 Hz or 60 Hz) equipment types. Furnaces being
operated at frequencies outside of the above-mentioned equipment types are not covered by
this document.

Varnost pri električnih grelnih inštalacijah in elektromagnetni obdelavi - 4. del: Posebne zahteve za inštalacije obločnih peči (IEC 60519-4:2021)

Ta del standarda IEC 60519 podaja posebne varnostne zahteve za inštalacije obločnih peči. Ta dokument opisuje vsa večja tveganja, nevarne situacije ali dogodke v zvezi z inštalacijami industrijskih obločnih peči, kot je navedeno v dodatku A, pri običajnem obratovanju in v razmerah posamične okvare ter pod pogoji razumno predvidljive nepravilne uporabe. Ta dokument določa zahteve, ki naj bi jih izpolnjeval proizvajalec za zagotovitev varnosti oseb in premoženja v celotnem življenjskem ciklu opreme od načrtovanja in začetka obratovanja, obratovanja, vzdrževanja, pregleda do prenehanja obratovanja ter v primeru predvidljivih razmer posamične okvare, do katerih lahko pride pri opremi. Nazivna napetost inštalacije obločnih peči je lahko v razponu nizke ali visoke napetosti (podrobnosti so podane v točki 4.2). Ta standard se uporablja za inštalacije obločnih peči, kot so: a) peči za neposredno obločno gretje, ki tvorijo obloke med elektrodo in kovino, npr. električna obločna peč, ki uporablja izmenični tok (EAF AC) ali enosmerni tok (EAF DC), in ponovčna peč (LF); b) peči za obločno uporovno gretje, ki tvorijo obloke med elektrodo in materialom naboja ali segrevajo material naboja z Joulovim učinkom, npr. obločna uporovna peč z zakritim oblokom, ki uporablja izmenični tok (SAF AC) ali enosmerni tok (SAF DC). OPOMBA 1: V nekaterih dokumentih se uporablja izraz »talilnica« ali »električna redukcijska peč«. Inštalacija peči za nenadzorovano obratovanje v tem dokumentu ni zajeta. Ta dokument ne podaja zahtev za tipsko preskušanje. OPOMBA 2: Industrijska oprema, ki jo zajema ta dokument, je običajno proizvedena kot samostojna enota ali kot zelo majhno število enot. Takšna enota ima običajno zelo visoko vrednost in lahko pri razpadu povzroči resno škodo. Ta dokument ne obravnava varnosti podatkov in tveganj, povezanih z zanemarjanjem varnosti. V zvezi s hrupom električne obločne peči se uporablja standard ISO 13578:2017, točka 6.1.23. Električna obločna peč, ki uporablja enosmerni tok, in obločna uporovna peč z zakritim oblokom, ki uporablja enosmerni tok, sta razvrščeni kot vrsta opreme z ničelno frekvenco (0 Hz). Električna obločna peč, ki uporablja izmenični tok, obločna uporovna peč z zakritim oblokom, ki uporablja izmenični tok, in ponovčna peč so razvrščene kot vrsta opreme z omrežno frekvenco (50 ali 60 Hz). Peči, ki obratujejo pri frekvencah zunaj razpona zgoraj navedenih vrst opreme, v tem dokumentu niso zajete.

SAFETY IN INSTALLATIONS FOR ELECTROHEATING
AND ELECTROMAGNETIC PROCESSING –

Part 4: Particular requirements for arc furnace 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.
IEC 60519-4 has been prepared by IEC technical committee 27: Industrial electroheating and
electromagnetic processing. It is an International Standard.
This fifth edition cancels and replaces the fourth edition published in 2013. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) the structure has been redrafted according to IEC 60519-1:2020;
b) the scope and object have been redrafted;
c) the terms and definitions
