This European Standard was approved by CENELEC on 2003-10-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Czech Republic,
Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and United Kingdom.

Foreword
The text of document 27/358/FDIS, future edition 3 of IEC 60519-1, prepared by IEC TC 27, Industrial
electroheating equipment, was submitted to the IEC-CENELEC parallel vote and was approved by
CENELEC as EN 60519-1 on 2003-10-01.
This European Standard supersedes EN 60519-1:1993.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2004-07-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2006-10-01
Significant technical changes with respect to EN 60519-1:1993 are as follows:
- the scope is now extended to cover also voltage band 3 equipment with rated voltage not exceeding
3 600 V a.c. or 5 000 V d.c.; the relevant provisions for such equipment have been added in clauses
on, for example protection against electric shock, equipotential bonding or maintenance work;
- requirements concerning equipotential bonding have been essentially modified and introduced in a
separate clause, based on the actual relevant provisions of EN 60204-1;
- general provisions on the impact of electromagnetic effects have been given;
- information concerning technical documentation has been modified;
- a bibliography has been added.
General test methods for industrial electroheating installations are specified in EN 60398:1999.
Additional information on non-electrical hazards possibly arising from the utilization of industrial electroheat
equipment may be taken from EN 746-1 (see Bibliography), which specifies common safety requirements
for industrial thermoprocessing equipment, as well as of an electrical and of a non-electrical kind.
Annexes designated "normative" are part of the body of the standard.
In this standard, annex ZA is normative.
Annex ZA has been added by CENELEC.
_________
Endorsement notice
