Primary batteries - Part 1: General (IEC 60086-1:2021)

This part of IEC 60086 is intended to standardize primary batteries with respect to dimensions,
nomenclature, terminal configurations, markings, test methods, typical performance, safety and
environmental aspects.
This document on one side specifies requirements for primary cells and batteries. On the other
side, this document also specifies procedures of how requirements for these batteries are to be
standardised.
As a classification tool for primary batteries, this document specifies system letters, electrodes,
electrolytes, and nominal as well as maximum open circuit voltage of electrochemical systems.
The object of this part of IEC 60086 is to benefit primary battery users, device designers and
battery manufacturers by ensuring that batteries from different manufacturers are
interchangeable according to standard form, fit and function. Furthermore, to ensure
compliance with the above, this part specifies standard test methods for testing primary cells
and batteries.
This document also contains requirements in Annex A justifying the inclusion or the ongoing
retention of batteries in the IEC 60086 series.

IEC 60086-1:2021 est disponible sous forme de IEC 60086-1:2021 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L’IEC 60086-1:2021 est destinée à normaliser les piles électriques en ce qui concerne les dimensions, la nomenclature, les configurations des bornes, les marquages, les méthodes d’essai, les caractéristiques types de fonctionnement, la sécurité et les aspects environnementaux. Le présent document spécifie d’une part les exigences pour les piles électriques. D’autre part, le présent document spécifie également des procédures de normalisation des exigences relatives à ces piles. En tant qu’outil de classification des piles électriques, le présent document spécifie les lettres des systèmes, les électrodes, les électrolytes et les tensions nominales, ainsi que maximales en circuit ouvert des systèmes électrochimiques. L’objectif de la présente partie de l’IEC 60086 est d’assurer aux utilisateurs, aux concepteurs de dispositifs et aux fabricants de piles que les piles de différents fabricants sont interchangeables par leur forme, leur montage et leur fonction. De plus, pour assurer la conformité à ce qui précède, la présente partie spécifie des méthodes d’essai normalisées pour les piles électriques.

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 injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 60086-1 has been prepared by IEC technical committee 35: Primary

cells and batteries.

This thirteenth edition cancels and replaces the twelfth edition published in 2015. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:
a) a compliance checklist was added as an Annex H;
b) definitions were harmonized with the other 60086 series documents;

c) the nominal voltage of the zinc air system is now listed as either 1,4 V or 1,45 V;

d) Annex F for calculation of MAD values was simplified;
e) a validity period for testing was added;
f) the accelerated aging test at 45 °C was changed from 13 to 4 weeks;

INTRODUCTION

The technical content of this part of IEC 60086 provides fundamental requirements and

information on primary cells and batteries. All batteries within the IEC 60086 series are

considered dry cell batteries. In this sense, IEC 60086-1 is the main component of the

IEC 60086 series and forms the basis for the subsequent parts. For example, this part includes

elementary information on definitions, nomenclature, dimensions and marking. While specific

requirements are included, the content of this part tends to explain methodology (how) and

justification (why).

Over the years, this part has been changed to improve its content and remains under continual

scrutiny to ensure that the publication is kept up to date with the advances in both battery and

battery-powered device technologies.

Safety requirements and recommendations are available in IEC 60086-4, IEC 60086-5 and

IEC 62281. Specifications are available in IEC 60086-2 and IEC 60086-3. Environmental

aspects are dealt with in IEC 60086-6.

1 Scope

This part of IEC 60086 is intended to standardize primary batteries with respect to dimensions,

nomenclature, terminal configurations, markings, test methods, typical performance, safety and

environmental aspects.

This document on one side specifies requirements for primary cells and batteries. On the other

side, this document also specifies procedures of how requirements for these batteries are to be

standardised.

As a classification tool for primary batteries, this document specifies system letters, electrodes,

electrolytes, and nominal as well as maximum open circuit voltage of electrochemical systems.

The object of this part of IEC 60086 is to benefit primary battery users, device designers and

battery manufacturers by ensuring that batteries from different manufacturers are

interchangeable according to standard form, fit and function. Furthermore, to ensure

compliance with the above, this part specifies standard test methods for testing primary cells

and batteries.

This document also contains requirements in Annex A justifying the inclusion or the ongoing

retention of batteries in the IEC 60086 series.
