APPLIANCE COUPLERS FOR HOUSEHOLD
AND SIMILAR GENERAL PURPOSES –
Part 2-2: Interconnection couplers for household
and similar equipment
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60320-2-2 has been prepared by subcommittee 23G: Appliance
couplers, of IEC technical committee 23: Electrical accessories.
This second edition cancels and replaces the first edition published in 1990, amendment 1
(1994) and amendment 2 (1997), and constitutes a minor revision.
The text of this standard is based on the following documents:
FDIS Report on voting
23G/183/FDIS 23G/187/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This standard is intended to be used in conjunction with IEC 60320-1: Appliance couplers for
household and similar general purposes (1994).
60320-2-2 © IEC:1998 – 7 –
The clauses of this standard supplement or modify the corresponding clauses of IEC 60320-1.
Where there is no corresponding subclause in this standard, the subclause of IEC 60320-1
applies without modification as far as is reasonable. Where this standard states "addition",
"modification" or "replacement", the relevant requirement, test specification or explanatory
matter in IEC 60320-1 should be adapted accordingly.
In this particular standard, subclauses, figures or tables which are additional to those in Part 1
are numbered starting from 101.

INTRODUCTION
Where in IEC 60320-1 the words "appliance coupler", "connector" or "appliance inlet" appear,
they should be deleted and replaced by "interconnection coupler", "plug connector" or
"appliance outlet" respectively.

APPLIANCE COUPLERS FOR HOUSEHOLD
AND SIMILAR GENERAL PURPOSES –
Part 2-2: Interconnection couplers for household
and similar equipment
1 Scope
This clause of IEC 60320-1 is replaced as follows:
This standard is applicable to two-pole interconnection couplers for a.c. only, with and without
earthing contact, with a rated voltage not exceeding 250 V and a rated current not exceeding
16 A, for household and similar appliances and equipment and intended for the interconnection
of the electrical supply to electrical appliances or equipment for 50 Hz or 60 Hz supply.
Appliance outlets integrated in or incorporated in appliances or other equipment are within the scope of this
standard. The dimensional and general requirements of this standard apply to such outlets, but certain tests may
not be relevant.
The requirements for plug connectors are based on the assumption that the temperature of
the socket contacts of the corresponding appliance outlets does not exceed 65 °C (cold
conditions).
Interconnection couplers complying with this standard are suitable for use at ambient
temperatures not normally exceeding 25 °C, but occasionally reaching 35 °C.
Interconnection couplers complying with the standard sheets in this standard are intended for
the interconnection of appliances or equipment having no special protection against moisture;
for the interconnection of other appliances or equipment and of an appliance or equipment
which is subject to spillage of liquid in normal use, additional requirements are necessary.
Special constructions may be required
– in locations where special conditions prevail as, for example, in ships, vehicles and the like;
– in hazardous locations, for example, where explosions are liable to occur.

3 Definitions
This clause of IEC 60320-1 applies with the following additions:
Additional definitions:
3.101 An interconnection coupler is a means enabling the connection and disconnection at
will of an appliance or equipment to a cord leading to another appliance or equipment.
It consists of two parts:
–a plug connector, which is the part integral with, or intended to be attached to, the cord;
– an appliance outlet, which is the part integrated or incorporated in the appliance or
equipment or intended to be fixed to it, and from which the supply is obtained.
NOTE – An appliance outlet integrated in an appliance or equipment is an appliance outlet (the shroud and bottom
of) which is formed by the housing of the appliance or equipment. An appliance outlet incorporated in an appliance
or equipment is a separate appliance outlet built in or fixed to an appliance or equipment.
3.3 Replacement:
The term "accessory" is used as a general term covering plug connectors and/or appliance
outlets.
4 General requirements
This clause of IEC 60320-1 is replaced as follows.
Interconnection couplers shall be so designed and constructed that in normal use their
performance is reliable and without danger to the user or surroundings.
In general, compliance is checked by carrying out all the tests specified.
