FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The 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.
The text of this standard is based on the following documents:
FDIS Report on voting
35/1127/FDIS 35/1130/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
IEC 60086 consists of the following parts, under the general title: Primary batteries:
Part 1: General
Part 2: Specification sheets
Part 3: Watch batteries
Part 4: Safety of lithium batteries
Part 5: Safety of batteries with aqueous electrolyte
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
Annexes A and B are for information only.

The committee has decided that the contents of this publication will remain unchanged until

2002. At this date, the publication will be

reconfirmed;
withdrawn;
replaced by a revised edition, or

amended.
A bilingual version of this publication may be issued at a later date.

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

This part of IEC 60086 specifies requirements and tests 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.
