SWITCHES FOR APPLIANCES –
Part 1-2: Requirements for electronic switches
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.

Additional specimens may be required depending on the construction and declaration of the switch.

Each electrical rating submitted to the testing of Clauses 16 and 17 requires an additional 3 specimens (such

as rating i = 3 specimens, rating ii = additional 3 specimens).

The specimen may be used for more than 1 test, if cumulative stress as a result of sequential testing is

avoided. When a specimen is damaged a new specimen shall be used for the next test.

In general 1 specimen for ingress of solid foreign objects (dust), and 1 specimen for ingress of water.

Specific IP ratings (such as IP5x, IP6x and protection against water) require a special enclosure to be

provided with the switch specimen in order to complete the testing.

The same test specimens are used to complete the testing of 14.3 and 15. The test are completed in

immediate sequence.

Heating and endurance is recommended to be tested on the same specimens. If declared, separate

specimens may be used when noted on the test record.

Three additional new specimens may be required according to Clause 20, for the test according to annex G.

For testing coatings on printed boards according to 20.4, the number of printed boards needed is determined

by the testing of IEC 60664-3.

For testing glow wire and ball pressure special test specimens according to 60695-2-11 and 60695-10-2,

respectively may be required.

The number of specimens for specific test and examination of Clause 24 is according to the individual

subclasses.

EMC testing may require additional specimens according to the EMC test program and switch construction.

Abnormal operation and fault conditions are generally destructive, typically the switch cannot be repaired

and reused for the next fault. Specially prepared specimens (such as with wires soldered to the internal

circuit) may be necessary in order to complete the testing. The total number of specimens depends on the

switch construction, for details see Clause 23.

This test is part of a sequence, and a new set of 3 specimens shall not be used except as permitted by 5.1.2.

SWITCHES FOR APPLIANCES –
Part 1-2: Requirements for electronic switches
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.

Additional specimens may be required depending on the construction and declaration of the switch.

Each electrical rating submitted to the testing of Clauses 16 and 17 requires an additional 3 specimens (such

as rating i = 3 specimens, rating ii = additional 3 specimens).

The specimen may be used for more than 1 test, if cumulative stress as a result of sequential testing is

avoided. When a specimen is damaged a new specimen shall be used for the next test.

In general 1 specimen for ingress of solid foreign objects (dust), and 1 specimen for ingress of water.

Specific IP ratings (such as IP5x, IP6x and protection against water) require a special enclosure to be

provided with the switch specimen in order to complete the testing.

The same test specimens are used to complete the testing of 14.3 and 15. The test are completed in

immediate sequence.

Heating and endurance is recommended to be tested on the same specimens. If declared, separate

specimens may be used when noted on the test record.

Three additional new specimens may be required according to Clause 20, for the test according to annex G.

For testing coatings on printed boards according to 20.4, the number of printed boards needed is determined

by the testing of IEC 60664-3.

For testing glow wire and ball pressure special test specimens according to 60695-2-11 and 60695-10-2,

respectively may be required.

The number of specimens for specific test and examination of Clause 24 is according to the individual

subclasses.

EMC testing may require additional specimens according to the EMC test program and switch construction.

Abnormal operation and fault conditions are generally destructive, typically the switch cannot be repaired

and reused for the next fault. Specially prepared specimens (such as with wires soldered to the internal

circuit) may be necessary in order to complete the testing. The total number of specimens depends on the

switch construction, for details see Clause 23.

This test is part of a sequence, and a new set of 3 specimens shall not be used except as permitted by 5.1.2.
