This European Standard was approved by CENELEC on 2013-09-30. 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 17A/1044/FDIS, future edition 1 of IEC 62271-4, 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 62271-4:2013.

The following dates are fixed:
(dop) 2014-06-30
• 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) 2016-09-30
standards conflicting with the
document have to be withdrawn
This document supersedes CLC/TR 62271-303:2009.

CLC/TR 62271-303:2009:
a) the description of the potential effects on health of SF by-products (former Annex D of
CLC/TR 62271-303:2009) has been replaced by the calculation methods for evaluating of the
potential effects on health of SF by-products (see Annex H);
b) information about cryogenic reclaim of SF have been added (see Annex I);
c) handling procedures for the most popular SF mixtures have been added (see Annex J).
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
