PRIMARY BATTERIES –

Part 4: Safety of lithium batteries

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
1
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.
