This European Standard was approved by CENELEC on 2011-01-03. 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, Bulgaria, Croatia, Cyprus,
the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,
Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia,

Foreword
The text of document 27/770/FDIS, future edition 4 of IEC 60519-1, prepared by IEC TC 27, Industrial
electroheating, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as
EN 60519-1 on 2011-01-03.
This European Standard supersedes EN 60519-1:2003.
The main technical changes with respect to EN 60519-1:2003 are as follows:
– scope and object have been modified, voltage limits and classification removed;
– terms/definitions, Annex ZA and bibliography have been updated and completed;
– Clause 4 on classification of equipment according to process frequency has been modified;
– Clause 5 (General requirements) has been redrafted and new provisions have been added (e.g.
relating to single fault conditions and EMF issues), following the recommendations of IEC Guide 104;
– Clause 8 has been redrafted, the contents of subclauses 8.2 and 8.3 has been moved to a new
normative Annex A and 8.4 has been deleted;
– a new Clause 12 (Protection against other hazards) has been added;
– clauses dealing with marking and documentation have been amended.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
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) 2011-10-03
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2014-01-03
Annex ZA has been added by CENELEC.
