This European Standard was approved by CENELEC on 2013-05-30. 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 104/595/FDIS, future edition 3 of IEC 60068-2-57, prepared by IEC TC 104
"Environmental conditions, classification and methods of test" was submitted to the IEC-CENELEC
parallel vote and approved by CENELEC as EN 60068-2-57:2013.
The following dates are fixed:
• latest date by which the document has (dop) 2014-02-28
to be implemented at national level by
publication of an identical national
standard or by endorsement
(dow) 2016-05-30
• latest date by which the national
standards conflicting with the

document have to be withdrawn
This document supersedes EN 60068-2-57:2000 and EN 60068-2-59:1993.
EN 60068-2-57:2000 and EN 60068-2-59:1993:
– editorially combines EN 60068-2-57 and EN 60068-2-59;
– the title has been modified to include a sine beat method.
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 60068-2-57:2013 was approved by CENELEC as a European
Standard without any modification.
In the official version, for Bibliography, the following notes have to be added for the standards indicated:
IEC 60068-2-59:1990 NOTE  Harmonised as EN 60068-2-59:1993 (not modified).
