82 FOREWORD
83 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
84 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
85 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
86 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
87 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
88 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
89 in the subject dealt with may participate in this preparatory work. International, governmental and non-
90 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
91 with the International Organization for Standardization (ISO) in accordance with conditions determined by
92 agreement between the two organizations.
93 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
94 consensus of opinion on the relevant subjects since each technical committee has representation from all
95 interested IEC National Committees.
96 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
97 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
98 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
99 misinterpretation by any end user.
100 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
101 transparently to the maximum extent possible in their national and regional publications. Any divergence
102 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
103 the latter.
104 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
105 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
106 services carried out by independent certification bodies.
107 6) All users should ensure that they have the latest edition of this publication.
108 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
109 members of its technical committees and IEC National Committees for any personal injury, property damage or
110 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
111 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
112 Publications.
113 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
114 indispensable for the correct application of this publication.
115 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
116 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
117 International Standard IEC 61316 has been prepared by subcommittee 23H: Plugs, socket-
118 outlets and couplers for industrial and similar applications, and for electric vehicles, of IEC
119 technical committee 23: Electrical accessories.
120 This third edition cancels and replaces the second edition, published in 1999, and constitutes
121 an editorial and technical revision.
122 This edition includes the following significant technical changes with respect to the previous
123 edition:
124 a) Implementation of the latest tests and requirements previously included in IEC 60309-1
125 publication;
126 In addition, this document implements the latest ISO/IEC Directives Part 2 Ed. 7.0 (2016-05):
127 principles and rules for the structuring and drafting of ISO and IEC documents;
128 The text of this International Standard is based on the following documents:

352 performance is reliable, and safety is achieved by reducing risk to a tolerable level, as defined
353 in ISO/IEC Guide 51
354 Unless otherwise stated, the normal use environment in which the cable reels complying with
355 this standard are normally used is pollution degree 3 according to IEC 60664-1.
356 If other pollution degrees are needed, creepage distances and clearances shall be in
357 accordance with IEC 60664-1. The comparative tracking index (CTI) value shall be evaluated
358 in accordance with IEC 60112. Test and requirements are specified in 21.1.2.
359 Cable reels shall have a minimum degree of protection IP24D (see 6.3) according to
360 IEC 60529.
361 In general, compliance is checked by carrying out all the tests specified.

363 are satisfied if all the tests are met. The sample is tested as delivered and under normal
364 conditions of use, at an ambient temperature of (20±5) °C. Tests are carried out in the order
