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 62133-1 has been prepared by subcommittee 21A: Secondary

cells and batteries containing alkaline or other non-acid electrolytes, of IEC technical

committee 21: Secondary cells and batteries.

---------------------- Page: 10 ----------------------
IEC 62133-1:2017 © IEC 2017 – 9 –

These tolerances comprise the combined accuracy of the measuring instruments, the

measurement techniques used, and all other sources of error in the test procedure.

The details of the instrumentation used shall be provided in any report of results.

5 General safety considerations
5.1 General

The safety of secondary cells and batteries requires the consideration of two sets of applied

conditions:
1) intended use;
2) reasonably foreseeable misuse.

Cells and batteries shall be so designed and constructed that they are safe under conditions

of both intended use and reasonably foreseeable misuse. It is expected that cells or batteries

subjected to misuse may fail to function following such experience. They shall not however

present significant hazards. It may also be expected that cells and batteries subjected to

intended use shall not only be safe but shall continue to be functional in all respects.

Potential hazards which are the subject of this document are:
• fire,
• burst/explosion,
• leakage of cell electrolyte,
• venting,
• burns from excessively high external temperatures,
• rupture of battery case with exposure of internal components.

Conformity with 5.2 to 5.7 for cells and batteries other than button cells is checked by

inspection, by the tests of Clauses 7, and in accordance with the appropriate standard (see

Clause 2 and Table 1).
5.2 Insulation and wiring

The insulation resistance between the positive terminal and externally exposed metal surfaces

of the battery excluding electrical contact surfaces shall be not less than 5 MΩ at 500 V DC

when measured 60 s after applying the voltage.

Internal wiring and insulation should be sufficient to withstand the maximum anticipated

current, voltage and temperature requirements. The orientation of wiring should be such that

adequate clearances and creepage distances are maintained between conductors. The

mechanical integrity of internal connections should be sufficient to accommodate conditions of

reasonably foreseeable misuse (i.e. solder alone is not considered a reliable means of

connection).
5.3 Venting

Battery cases and cells shall incorporate a pressure relief mechanism or shall be so

constructed that they will relieve excessive internal pressure at a value and rate that will

preclude rupture, explosion and self-ignition. If encapsulation is used to support cells within

an outer case, the type of encapsulant and the method of encapsulation shall neither cause

the battery to overheat during normal operation nor inhibit pressure relief.
---------------------- Page: 11 ----------------------
– 10 – IEC 62133-1:2017 © IEC 2017
5.4 Temperature, voltage and current management

The design of batteries shall be such that abnormal temperature-rise conditions are

prevented. Batteries shall be designed to be within temperature, voltage and current limits

specified by the cell manufacturer. Batteries shall be provided with specifications and

charging instructions for equipment manufacturers so that associated chargers are designed

to maintain charging within the temperature, voltage and current limits specified.

Where necessary, applicable means can be provided to limit current to safe levels during

charge and discharge.
5.5 Terminal contacts

The size and shape of the terminal contacts shall ensure that they can carry the maximum

anticipated current. External terminal contact surfaces shall be formed from conductive

materials with good mechanical strength and corrosion resistance. Terminal contacts shall be

arranged so as to minimize the risk of short circuits.
5.6 Assembly of cells into batteries

If there is more than one battery housed in a single battery case, cells used in the assembly

of each battery shall have closely matched capacities, be of the same design, be of the same

chemistry and be from the same manufacturer. The battery shall have some type of safety

device or feature for charging.

Manufacturers of cells shall specify current, voltage and temperature limits so that the battery

manufacturer/designer may ensure proper design and assembly.

Batteries that are designed for the selective discharge of a portion of their series connected

cells shall incorporate circuitry to prevent operation of cells outside the limits specified by the

cell manufacturer.

Protective circuit components should be added as appropriate and consideration given to the

end-device application. When testing a battery, the manufacturer of the battery should provide

a test report confirming the compliance according to this document.
5.7 Quality plan

The manufacturer shall prepare and implement a quality plan that defines procedures for the

inspection of materials, components, cells and batteries and which covers the whole process

of producing each type of cell or battery. Manufacturers should understand their process

capabilities and should institute the necessary process controls as they relate to product

safety.
