This European Standard was approved by CENELEC on 2013-10-14. 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 CEN-CENELEC Management Centre 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 CEN-CENELEC Management Centre 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, Former Yugoslav Republic of Macedonia, France, Germany,
Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland,
Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

Foreword
The text of document 27/926/FDIS, future edition 2 of IEC 62395-1, prepared by IEC/TC 27 "Industrial
electroheating and electromagnetic processing" was submitted to the IEC-CENELEC parallel vote and
approved by CENELEC as EN 62395-1:2013.

The following dates are fixed:
(dop) 2014-07-14
• latest date by which the document has to be
implemented at national level by
publication of an identical national
standard or by endorsement
• latest date by which the national (dow) 2016-10-14
standards conflicting with the
document have to be withdrawn
This document supersedes EN 62395-1:2006.

EN 62395-1:2006:
- tests have been added for trace heating on sprinkler systems;
- the flammability test has been changed to align with the latest draft of future
1)
IEC/IEEE 60079-30-1 ;
- a supplementary test has been added for the verification of sheath temperature using trace heating
mounted on a plate fixture.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such
patent rights.
This standard covers the Principle Elements of the Safety Objectives for Electrical Equipment
Designed for Use within Certain Voltage Limits (LVD - 2006/95/EC).

Endorsement notice
The text of the International Standard IEC 62395-1:2013 was approved by CENELEC as a European
Standard without any modification.
