48 FOREWORD
49 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
50 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
51 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
52 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
53 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
54 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
55 in the subject dealt with may participate in this preparatory work. International, governmental and non-
56 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
57 with the International Organization for Standardization (ISO) in accordance with conditions determined by
58 agreement between the two organizations.59 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
60 consensus of opinion on the relevant subjects since each technical committee has representation from all
61 interested IEC National Committees.62 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
63 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
64 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
65 misinterpretation by any end user.66 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
67 transparently to the maximum extent possible in their national and regional publications. Any divergence
68 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
69 the latter.70 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
71 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
72 services carried out by independent certification bodies.73 6) All users should ensure that they have the latest edition of this publication.
74 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
75 members of its technical committees and IEC National Committees for any personal injury, property damage or
76 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
77 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
78 Publications.79 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
80 indispensable for the correct application of this publication.81 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
82 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
83 International Standard IEC 60309-2 has been prepared by subcommittee SC 23H: Plugs,
84 socket-outlets and couplers for industrial and similar applications, and for electric vehicles, of
85 IEC technical committee 23: Electrical accessories.86 This fifth edition cancels and replaces the fourth edition published in 1999, Amendment
87 1:[2005] and Amendment 2:[2012]. This edition constitutes a technical revision.
88 This edition includes the following significant technical changes with respect to the previous
89 edition:90 a) addition of requirements and test for non-solid pins;
91 b) additional rating IPX9;
92 c) additional marking to indicate neutral terminal and/or earthing terminal.
93 The text of this International Standard is based on the following documents:

287 Deviations from the dimensions specified in the standard sheets may be made, but only if
288 they provide a technical advantage and do not adversely affect the purpose and safety of the
289 accessories complying with the standard sheets, especially with regard to compatibility and
290 non-compatibility.291 Compliance is checked by means of gauges or by measurement for those dimensions not
292 covered by gauges,293 – for accessories having rated operating voltages exceeding 50 V according to:
294 • Figures 201 and 202 for socket-outlets;295 • Figures 203 and 204 for plugs and appliance inlets;
296 – for accessories having rated operating voltages not exceeding 50 V according to:
297 • Figures 205 and 206 for 16/20 A and 32/30 A accessories.298 The gauges shall be moved axially to the centre line of the accessory with a force as shown in
