APPLIANCE COUPLERS FOR HOUSEHOLD
AND SIMILAR GENERAL PURPOSES –
Part 3: Standard sheets and gauges
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.
International Standard IEC 60320-3 has been prepared by subcommittee 23G: Appliance
couplers, of IEC technical committee 23: Electrical accessories.
The text of this standard is based on the following documents:
FDIS Report on voting
23G/336/FDIS 23G/338/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 publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

A list of all the parts in the IEC 60320 series, under the general title Appliance couplers for
household and similar general purposes, can be found on the IEC website.
This part is to be used in conjunction with IEC 60320-1.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

6.14 "GO" gauge for appliance inlets to standard sheets C10
It shall be possible to insert the connector fully into the gauge shown in Figure 13 with a force
not exceeding 60 N.
The thickness of the gauge plate K, as well as the nominal values of the dimensions s and t of
the handle and of the hole in the gauge plate, are left free, but the tolerances h7 and F8 shall
be respected.
The plane A-A of the inlet shall lie between planes B-B and C-C of the gauge.
Then the gauge plate K shall be pushed over the handle to check the free area around the

6.32 Gauges for checking the distance from the engagement face of connectors and
appliance outlets to the point of first contact
The appropriate gauge shall be applied to the entry hole of each socket contact of the
connector with a force not exceeding 5 N. When the gauge is fully inserted, the longer pin of
the gauge ("contact gauge") shall make contact and the shorter pin ("no contact gauge") shall
not make contact (see Figure 31). See Table 3 for dimensions of contact gauge.
An electrical indicator with a voltage between 24 V and 50 V is used to show contact with the
relevant socket contact.
