This European Standard was approved by CENELEC on 2012-07-03. 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 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,

Foreword
The text of document 17A/997/FDIS, future edition 2 of IEC 62271-107, prepared by SC 17A, "High-
voltage switchgear and controlgear", of IEC TC 17, "Switchgear and controlgear" was submitted to the
IEC-CENELEC parallel vote and approved by CENELEC as EN 62271-107:2012.

The following dates are fixed:
(dop) 2013-04-03
• 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) 2015-07-03

standards conflicting with the
document have to be withdrawn
This document supersedes EN 62271-107:2005.
107:2005:
– the reference to EN 60694 has been changed to EN 62271-1;
– the new clauses and subclauses from EN 62271-1 have been added and where necessary new
wording has been provided:
 4.11 Rated filling levels for insulation and/or operation;
 5.19 X-ray emission;
 5.20 Corrosion;
 6.10 Additional tests on auxiliary and control circuits;
 6.11 X-radiation test procedure for vacuum interrupters;
 12 Influence of the product on the environment;
– the normative references have been updated: EN 60265-1 to EN 62271-103, IEC 60787 to
IEC/TR 60787, IEC 60466 to EN 62271-201, and IEC/TR 60787 was moved to the bibliography;
– the figures and tables have been placed in the document where they are first cited;
– the numbering of figures and tables has been changed to obtain the correct order;
– the definition of NSDD was deleted. This definition is included in EN 62271-1;
– the acceptance criteria have been aligned with 6.101.4 of EN 62271-103:2011;
– the various provisions expressed about "extension of the validity of type tests" have been grouped
under 6.103: some of the rules were duplicated in Clauses 6 and 8, and it seems better fitted to deal
within each type test sub-clause only with the type test to be performed. Conditions have not been
changed, but the wording is clearer;
– new numbering of subclauses in Clauses 8 and 9 to avoid conflict with clauses from EN 62271-1.

- 3 - EN 62271-107:2012
This International Standard is to be read in conjunction with EN 62271-1:2008, to which it refers and
which is applicable unless otherwise specified. In order to simplify the indication of corresponding
requirements, the same numbering of clauses and subclauses is used as in EN 62271-1. Amendments to
these clauses and subclauses are given under the same numbering, whilst additional subclauses, are
numbered from 101.
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.
Endorsement notice
The text of the International Standard IEC 62271-107:2012 was approved by CENELEC as a European
Standard without any modification.
