PRIMARY BATTERIES –
Part 5: Safety of batteries with aqueous electrolyte
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 60086-5 has been prepared by IEC technical committee 35:
Primary cells and batteries.
This third edition cancels and replaces the second edition (2005) and constitutes a technical
revision.
The major technical changes with respect to the previous edition are the test requirements
and the harmonization of the marking clause with the other standards of the IEC 60086 series.
Moreover, the table of safety pictograms was added as Annex C.

INTRODUCTION
The concept of safety is closely related to safeguarding the integrity of people and property.
This part of IEC 60086 specifies tests and requirements for primary batteries with aqueous
electrolyte and has been prepared in accordance with ISO/IEC guidelines, taking into account
all relevant national and international standards which apply. Also included in this standard is
guidance for appliance designers with respect to battery compartments and information
regarding packaging, handling, warehousing and transportation.
Safety is a balance between freedom from risks of harm and other demands to be met by the
product. There can be no absolute safety. Even at the highest level of safety, the product can
only be relatively safe. In this respect, decision-making is based on risk evaluation and safety
judgement.
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 standard, when followed on
a judicious "use when applicable" basis, will provide reasonably consistent standards for
safety.
