This European Standard was approved by CENELEC on 2011-03-02. 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,
Spain, Sweden, Switzerland and the United Kingdom.

Foreword
The text of document 35/1286/FDIS, future edition 3 of IEC 60086-3, prepared by IEC TC 35, Primary
cells and batteries, and ISO TC 114, Horology, was submitted to the IEC-CENELEC parallel vote and
was approved by CENELEC as EN 60086-3 on 2011-03-02.
This European Standard supersedes EN 60086-3:2005.
The major technical changes with respect to EN 60086-3:2005 are the drawings, a review of the table of
electrochemical systems and a harmonization of the marking clause with the other standards of the
EN 60086 series. Moreover, the table of the leakage levels was extended by adding drawings with better
visualization.
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) 2011-12-02
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2014-03-02
Annex ZA has been added by CENELEC.
__________
Endorsement notice
The text of the International Standard IEC 60086-3:2011 was approved by CENELEC as a European
Standard without any modification.
In the official version, for Bibliography, the following note has to be added for the standard indicated:
IEC 60068-2-78:2001 NOTE  Harmonized as EN 60068-2-78:2001 (not modified).
