APPLIANCE COUPLERS FOR HOUSEHOLD
AND SIMILAR GENERAL PURPOSES –
Part 2-3: Appliance couplers with a degree of protection higher than IPX0
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 60320-2-3 has been prepared by subcommittee 23G: Appliance
couplers, of IEC technical committee 23: Electrical accessories.
The text of this part is based on the following documents:
FDIS Report on voting
23G/185/FDIS 23G/188/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 part 2 is to be used in conjunction with IEC 60320-1: Appliance couplers for household
and similar general purposes – Part 1: General requirements. It was established on the basis of
the first edition of that standard (1994) and its amendments 1 (1995) and 2 (1996).
The clauses of this standard supplement or modify the corresponding clauses in IEC 60320-1.
When a particular subclause of part 1 is not mentioned in this part 2, the subclause of
IEC 60320-1 applies as far as is reasonable. Where this standard states “addition”,
“amendment” or “replacement”, the relevant requirement, test specification or explanatory
matter in IEC 60320-1 is to be adapted accordingly.

60320-2-3 © IEC:1998 – 7 –
Subclauses which are additional to those in part 1 are numbered starting from 101.
Annex A is for information only.
In this particular standard the following print types are used:
– requirements: in roman type;
– test specifications: in italic type;
– explanatory matter: in smaller roman type.

Part 2-3: Appliance couplers with a degree of protection higher than IPX0
1 Scope
This clause of IEC 60320-1 applies amended as follows:
This standard applies to two-pole non-reversible appliance couplers for cold conditions for a.c.
only, with a degree of protection against ingress of water higher than IPX0, with a rated voltage
not exceeding 250 V and a rated current not exceeding 10 A for a 50 Hz or 60 Hz supply.
They are intended for the connection of the supply cord to portable electrical appliances of
class II for household, commercial and light industrial use.
