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.
This redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition. A vertical bar appears in the margin wherever a change
has been made. Additions are in green text, deletions are in strikethrough red text.

• functional insulation: between the different poles of a switch. For the purpose of the test,
all the parts of each pole are connected together;

• basic insulation: between all live parts connected together and a metal foil covering the
outer accessible surface of the basic insulation and accessible metal parts in contact with
the basic insulation;
• double insulation: between all live parts connected together and a metal foil covering the
outer, normally not accessible, surface of basic insulation and non-accessible metal parts;
then: between two metal foils covering separately the inner, normally not accessible,
surface of supplementary insulation and connected to non-accessible metal parts, and the
outer accessible surface of supplementary insulation and connected to accessible metal
parts;
• reinforced insulation: between all live parts connected together and a metal foil covering
the outer accessible surface of reinforced insulation and accessible metal parts;
• contacts: between the open contacts of each pole of a switch at the test voltages for
"across electronic disconnection".
The foils are not pressed into openings but are pushed into corners and the like by means of
the standard test finger.
In cases where basic insulation and supplementary insulation cannot be tested separately,
the insulation provided is subjected to the test voltages specified for reinforced insulation.
For electronic switches, the test is carried out at the test voltages for "across full
disconnection" and "across micro-disconnection" only on electronic switches with mechanical
switching devices connected in series with the semiconductor switching device. For electronic
switches, The tests are not carried out across protective impedances and poles
interconnected by components.

2)
The specified making conditions are maintained for a period between 50 ms and 100 ms, and are then
reduced by an auxiliary switch to the specified breaking conditions.
For all switches except electronic switches the test current may be reduced to I-R by introducing a resistor in
the circuit. Short interruptions of the test current during the reduction to I-R not exceeding a period of 50 ms
to 100 ms are permitted.
For electronic switches, the reduction to the break current should be achieved without any open circuiting of
the simulated inductive loads circuit, to ensure that no abnormal voltage transients are generated.
A typical method of achieving this is shown in Figure 19.
3)
Resistors and inductors are not connected in parallel except that if any air-core inductor is used, a resistor
taking approximately 1 % of the current through the inductor is connected in parallel with it. Iron-core
inductors may be used provided that the current has a substantial sine-wave form. For three-phase tests,
three-core inductors are used.
4)
The test circuit condition for testing electronic switches, according to Figure 18, shall be substantially
resistive.

The specified making conditions are maintained for a period between 50 ms and 100 ms, and are then
reduced by an auxiliary switch to the specified breaking conditions.
For all switches except electronic switches the test current may be reduced to I-R by introducing a resistor
in the circuit. Short interruptions of the test current during the reduction to I-R not exceeding a period of
50 ms to 100 ms are permitted.
For electronic switches, the reduction to the break current should be achieved without any open circuiting
of the simulated inductive loads circuit, to ensure that no abnormal voltage transients are generated.
A typical method of achieving this is shown in Figure 16.
3)
Resistors and inductors are not connected in parallel except that if any air-core inductor is used, a
resistor taking approximately 1 % of the current through the inductor is connected in parallel with it. Iron-core
inductors may be used provided that the current has a substantial sine-wave form. For three-phase
tests, three-core inductors are used.
4)
The test circuit condition for testing electronic switches, according to Figure 16, shall be substantially
resistive.
