Primary batteries - Part 3: Watch batteries
IEC 60086-3:2016 is available as IEC 60086-3:2016 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 60086-3:2016 specifies dimensions, designation, methods of tests and requirements for primary batteries for watches. In several cases, a menu of test methods is given. When presenting battery electrical characteristics and/or performance data, the manufacturer specifies which test method was used. This fourth edition cancels and replaces the third edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- A harmonization of the cell sizes and service output tests with IEC 60086-2;
- Clarifications of Clauses 6: Sampling and Quality Assurance, 7: Test methods, and 8: Visual examination and acceptance condition;
- Harmonization of temperature and humidity conditions with IEC 60086-1. This publication is published as a double logo standard. Keywords: primary batteries for watches
Piles électriques - Partie 3: Piles pour montres
L'IEC 60086-3:2016 spécifie les dimensions, la désignation, les méthodes d'essai et les exigences applicables aux piles électriques pour montres. Dans certains cas, un choix de méthodes d'essai est proposé. Lorsque le fabricant présente les caractéristiques électriques et/ou les performances de la pile, il précise la méthode d'essai qui a été utilisée. Cette quatrième édition annule et remplace la troisième édition parue en 2011. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- Harmonisation des tailles des éléments et des essais de capacité avec l'IEC 60086-2;
- Clarification des Articles 6: Echantillonnage et assurance de la qualité, 7: Méthodes d'essai, et 8: Examen visuel et conditions d'acceptation;
- Harmonisation des conditions de température et d'humidité avec celles de l'IEC 60086-1. La présente norme est une norme double logo. Mots clés: piles électriques pour montres

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal
