PLUGS AND SOCKET-OUTLETS FOR HOUSEHOLD
AND SIMILAR PURPOSES –
Part 2-2: Particular requirements for socket-outlets for appliances

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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.

24.101 Mechanical strength of socket-outlets for appliances
Socket-outlets for appliances are checked by applying blows by means of the spring-hammer
test apparatus as described in IEC 60068-2-75.
All surfaces which are accessible when the socket-outlet for appliances is mounted as in normal
use are tested with the above test apparatus.
Socket-outlets integral with or designed to be incorporated in an appliance are tested as in
normal use.
Socket-outlets designed to be fixed to an appliance are mounted on a vertical sheet of plywood
8 mm thick and 175 mm square without any metallic back plate, the plywood being mounted on
a rigid frame which is fixed to a solid wall of brick, concrete or the like.

– 12 – IEC 60884-2-2:2025 RLV © IEC 2025
Blows are applied to all accessible surfaces, the test apparatus being calibrated to deliver an
energy corresponding to that delivered by the striking element of the pendulum, as shown in
the relevant figures and Table 21 of Part 1 as shown in Table 103.
For all such surfaces, three blows are applied to each of the three weakest points (maximum
nine blows).
NOTE 1 The following energy values of the spring hammer are considered as corresponding to those delivered by
the pendulum. See Table 103.

from the wall) after mounting as in normal use, with the exception of the above parts A.
D Parts which project more than 25 mm from the mounting surface (distance from the wall) after mounting
as in normal use, with the exception of the above parts A.

Care is taken that the results from one series of three blows do not influence subsequent series.
If there is doubt as to whether a defect has been caused by the application of preceding blows,
this defect is neglected and the group of three blows which led to the defect is applied to the
same place on a new sample, which shall then comply with the test.
After the test, the specimens shall show no damage within the meaning of this document: in
particular, live parts shall not have become accessible to the test probe B of IEC 61032.
NOTE 2 Damage to the finish, small dents which do not reduce creepage distances or
clearances below the values specified in 27.1 and small chips which do not adversely affect the
protection against electric shock or harmful ingress of water are neglected.
Cracks not visible with normal or corrected vision, without additional magnification, and surface
cracks in fibre-reinforced mouldings and the like, are ignored.

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.

PLUGS AND SOCKET-OUTLETS FOR HOUSEHOLD
AND SIMILAR PURPOSES –
Part 2-2: Particular requirements for socket-outlets for appliances

1 Scope
This part of IEC 60884 applies to socket-outlets for AC only, with or without earthing contact,
with a rated voltage not exceeding 250 V and a rated current not exceeding 16 A, which are
integrated or intended to be incorporated in or fixed to appliances, hereafter referred to as
socket-outlets for appliances.
Compatible plugs and socket-outlets, when combined, form a plug and socket-outlet system.
Standardized systems used around the world are reported in IEC/TR 60083.
The rated current is limited to 16 A maximum for accessories provided with screwless-type
terminals.
This document covers only those requirements for mounting boxes which are necessary for the
tests on the socket-outlet.
NOTE 1 Requirements for general purpose mounting boxes are given in IEC 60670-1.
This document also applies to:
– plugs which are a part of cord sets;
– plugs and portable socket-outlets which are a part of cord extension sets;
– plugs and socket-outlets which are a component of an appliance, unless otherwise stated
in the standard for the relevant appliance; and
– plugs and socket-outlets incorporating pilot lights.
Socket-outlets for appliances are intended to be used in stationary equipment and appliances,
