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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.

5.2 Unless otherwise specified, the specimens are tested as delivered and under normal
conditions of use.
Non-rewirable accessories are tested with the type and size of flexible cable as delivered;
those not incorporated in a cord set or a cord extension set, or which are not a component of
equipment, shall be provided, for testing, with at least 1 m of flexible cable.
Non-rewirable multiple portable socket-outlets are tested with flexible cables as delivered.
Socket-outlets which do not comply with any accepted standard sheet are tested together with
the corresponding boxes.
Socket-outlets which require a box to complete their enclosure are tested with their boxes.
5.3 Unless otherwise specified, the tests are carried out in the order of the clauses, at an
ambient temperature between 15 °C and 35 °C.
In case of doubt, the tests are made at an ambient temperature of (20 ± 5) °C.
Plugs and socket-outlets are tested separately.
The neutral, if any, is treated as a pole.
5.4 Three specimens are subjected to all the relevant tests.
For the tests of 12.3.11, additional specimens of socket-outlets having in total at least five
screwless terminals are required.
For the tests of 12.3.12, three additional specimens of socket-outlets are necessary; in each
specimen one clamping unit is tested.
For each of the tests of 13.22 and 13.23, three additional specimens of separate membranes,
or of accessories incorporating membranes, are required.
For non-rewirable accessories, six additional specimens are required for the test of 23.2
and 23.4.
For the tests of Clauses 20 and 21 additional specimens may be necessary (see Clauses 20
and 21, and Figure 43).
For the test of 24.10, three additional specimens are required.
For the test of clause 28, three additional specimens may be necessary.
NOTE A table showing the number of specimens needed for the tests is given in annex B.
5.5 The specimens are submitted to all the relevant tests and the requirements are satisfied
if all the tests are met.
60884-1  IEC:2002+A1:2006 – 27 –
If one specimen does not satisfy a test due to an assembly or a manufacturing fault, that test
and any preceding one which may have influenced the results of the test shall be repeated,
and also the tests which follow shall be made in the required sequence on another full set of
specimens, all of which shall comply with the requirements.
NOTE The applicant may submit, together with a number of specimens specified in 5.4, the additional set of
specimens which may be required, should one specimen fail. The testing station will then, without further request,
test the additional specimens and will only reject them if a further failure occurs. If the additional set of specimens
is not submitted at the same time, the failure of one specimen will entail rejection.
5.6 Routine tests are specified in annex A.
