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.

INTRODUCTION
Principles of safety
General
This introduction is intended to provide an appreciation of the principles on which the
requirements of this standard are based. Such an understanding is essential in order that safe
apparatus can be designed and manufactured.
The requirements of this standard are intended to provide protection to persons as well as to
the surroundings of the apparatus.
Attention is drawn to the principle that the requirements, which are standardized, are the
minimum considered necessary to establish a satisfactory level of safety.
Further development in techniques and technologies may entail the need for future modification
of this standard.
NOTE The expression "protection to the surroundings of the apparatus" implies that this protection should also
include protection of the natural environment in which the apparatus is intended to be used, taking into account the
life cycle of the apparatus, i.e. manufacturing, use, maintenance, disposal and possible end-of-life recycling of parts
of the apparatus.
Hazards
The application of this standard is intended to prevent injury or damage due to the following
hazards:
– electric shock;
– excessive temperatures;
– radiation;
– implosion;
– mechanical hazards;
– fire;
– chemical burns (for example, as a result of the ingestion of lithium chemistry button/coin
cells).
Electric shock
Electric shock is due to current passing through the human body. Currents of the order of a
milliampere can cause a reaction in persons in good health and may cause secondary risks
due to involuntary reaction. Higher currents can have more damaging effects. Voltages below
certain limits are generally regarded as not dangerous under specified conditions. In order to
provide protection against the possibility of higher voltages appearing on parts that may be
touched or handled, such parts are either earthed or adequately insulated.
For parts which can be touched, two levels of protection are normally provided to prevent
electric shock caused by a single fault. Thus a single fault and any consequential faults will not
create a hazard. The provision of additional protective measures, such as SUPPLEMENTARY
INSULATION or protective earthing, is not considered a substitute for, or a relief from, properly
designed BASIC INSULATION.
– 8 – IEC 60065:2014 © IEC 2014
Cause Prevention
Contacts with parts normally at hazardous Prevent access to parts at hazardous
voltage. voltage by fixed or locked covers, interlocks,
etc.
Discharge capacitors at hazardous voltages.

Breakdown of insulation between parts Either use double or reinforced insulation
normally at hazardous voltage and between parts normally at hazardous
accessible parts. voltages and accessible parts so that
breakdown is not likely to occur, or connect
accessible conductive parts to protective
earth so that the voltage which can develop
is limited to a safe value. Provide adequate
mechanical and electrical strength.

Breakdown of insulation between parts Segregate hazardous and non-hazardous
normally at hazardous voltage and circuits voltage circuits either by double or
normally at non-hazardous voltages, thereby reinforced insulation so that breakdown is
putting accessible parts and terminals at not likely to occur, or by a protective earthed
hazardous voltage. screen, or connect the circuit normally at
non-hazardous voltage to protective earth,
so that the voltage which can develop is
limited to a safe value.
Touch current from parts at hazardous Limit touch current to a safe value or
voltage through the human body. provide a protective earthing connection to
the accessible parts.
(Touch current can include current due to
RFI filter components connected between
mains supply circuits and accessible parts
or terminals.)
Excessive temperatures
Requirements are included to prevent injury due to excessive temperatures of accessible parts,
to prevent damaging of insulation due to excessive internal temperatures, and to prevent
mechanical instability due to excessive temperatures developed inside the apparatus.
Radiation
Requirements are included to prevent injury due to excessive energy levels of ionizing and
laser radiation, for example by limiting the radiation to non-hazardous values.
Implosion
Requirements are included to prevent injury due to implosion of picture tubes.
Mechanical hazards
Requirements are included to ensure that the apparatus and its parts have adequate
mechanical strength and stability, to avoid the presence of sharp edges and to provide
guarding or interlocking of dangerous moving parts.

Fire
A fire can result from:
– heat;
– arcing;
caused by
– overloads;
– component failure;
– insulation breakdown;
– bad connections;
– conductor breakage.
Requirements are included that are intended to prevent fire originating within the apparatus
from spreading beyond the immediate vicinity of the source of the fire or from causing damage
to the surroundings of the apparatus.
The following preventive measures are recommended:
– the use of suitable components and subassemblies;
– the prevention of excessive temperature rise that might cause ignition under normal or fault
conditions;
– the use of measures to eliminate POTENTIAL IGNITION SOURCES such as inadequate contacts,
bad connections, interruptions;
– the limitation of the quantity of combustible material used;
– the control of the position of combustible materials in relation to POTENTIAL IGNITION
SOURCES;
– the use of materials with high resistance to fire in the vicinity of POTENTIAL IGNITION
SOURCES;
– the use of encapsulation or barriers to limit the spread of fire within the apparatus;
– the use of suitable fire retardant materials for the enclosure.
