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 60086-4 has been prepared by technical committee 35: Primary

cells and batteries.

This fifth edition cancels and replaces the fourth edition published in 2014. This edition

constitutes a technical revision.

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

edition:
a) Revised criteria for an explosion;

b) Addition of test parameters for the overdischarge test of battery types FR14505 and

FR10G445;
c) Addition of a new subclause 5.1 Validity of Testing;
d) revised pictogram E in Table D.1;

e) Addition of Annex E with requirements for child resistant packaging of coin cells;

INTRODUCTION

The concept of safety is closely related to safeguarding the integrity of people and property.

This document specifies tests and requirements for lithium batteries and has been prepared in

accordance with ISO/IEC guidelines, taking into account all relevant national and international

standards which apply.

Lithium batteries are different from conventional primary batteries using aqueous electrolyte

in that they contain flammable materials.

Consequently, it is important to carefully consider safety during design, production,

distribution, use, and disposal of lithium batteries. Based on such special characteristics,

lithium batteries for consumer applications were initially small in size and had low power

output. There were also lithium batteries with high power output which were used for special

industrial and military applications and were characterized as being “technician replaceable”.

The first edition of this document was drafted to accommodate this situation.

However, from around the end of the 1980s, lithium batteries with high power output started to

be widely used in the consumer replacement market, mainly as a power source in camera

applications. Since the demand for such lithium batteries with high power output significantly

increased, various manufacturers started to produce these types of lithium batteries. As a

consequence of this situation, the safety aspects for lithium batteries with high power output

were included in the second edition of this document.

Primary lithium batteries both for consumer and industrial applications are well-established

safe and reliable products in the market, which is at least partly due to the existence of safety

standards such as this document and, for transport, IEC 62281. The fourth edition of this

document therefore reflects only minor changes which became necessary in order to keep it

harmonized with IEC 62281 and to continuously improve the user information about safety

related matters.

Guidelines addressing safety issues during the design of lithium batteries are provided in

Annex A. Annex B provides guidelines addressing safety issues during the design of

equipment where lithium batteries are installed. Both Annex A and B reflect experience with

lithium batteries used in camera applications and are based on [23] .

Safety is freedom from unacceptable risk. There can be no absolute safety: some risk will

remain. Therefore a product, process or service can only be relatively safe. Safety is achieved

by reducing risk to a tolerable level determined by the search for an optimal balance between

the ideal of absolute safety and the demands to be met by a product, process or service, and

factors such as benefit to the user, suitability for purpose, cost effectiveness, and conventions

of the society concerned.

As safety will pose different problems, it is impossible to provide a set of precise provisions

and recommendations that will apply in every case. However, this document, when followed

on a judicious “use when applicable” basis, will provide reasonably consistent standards for

safety.
