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 60309-5 has been prepared by subcommittee 23H: Plugs, socket-
outlets and couplers for industrial and similar applications, and for electric vehicles, of IEC
technical committee 23: Electrical accessories.

couplers for industrial purposes can be found on the IEC website.
This part of IEC 60309 is to be read in conjunction with IEC 60309-1. The clauses of the
particular requirements of this document supplement or modify the corresponding clauses of
IEC 60309-1. Where the text indicates an "addition" to or a "replacement" of the relevant
requirement, test specification or explanation of IEC 60309-1, these changes are made to the
relevant text of IEC 60309-1, which then becomes part of the standard. Where no change is
necessary, the words "Clause X of IEC 60309-1:1999 + A1:2005 + A2:2012 applies" are used.

INTRODUCTION
International Standard IEC 60309-5 has been written to address the needs in terms of plugs,
socket-outlets and ship couplers (ship connectors and ship inlets), herein referred to as
“accessories”, of IEC/IEEE 80005-3 . The purpose of IEC/IEEE 80005-3 is to define
requirements that allow compliant ships to connect to compliant low-voltage shore power
supplies through standardized shore-to-ship connection accessories.
Ships that do not require connecting with standardized low-voltage shore power supplies as
above may use accessories that are not covered by the standard sheets of IEC 60309-5 but
they may find it impossible to connect to these shore supplies.
Other low-voltage plugs, socket-outlets, ship connectors and ship inlets used for the
connection of certain ship types to low-voltage shore power supplies may be found in the
IEC 60309 series.
International Standard IEC 60309 is divided into several parts: IEC 60309-1 is entitled
General requirements, and comprises clauses of a general nature. The subsequent parts
address requirements dealing with particular devices.

pilot contacts.
NOTE 1 In the following countries the term “ground” is used instead of “earth": US.
These accessories have a maximum rated current of 350 A and a maximum rated operating
voltage not exceeding 690 V 50/60 Hz.
NOTE 2 The various operating currents, voltages and frequencies required for various types of ship are set by the
shore supply system described in IEC/IEEE 80005-3.
These accessories are intended to be installed and operated by instructed persons
(IEC 60050-195:1998, Amendment 1:2001, 195-04-02) or skilled persons

Accessories and their mounting means shall be constructed to resist the corrosion induced by

Ferrous parts, including enclosures, shall be adequately protected against rusting.
Compliance is checked with the following test:
Parts to be tested are subjected to a salt spray (fog) using the test method in Salt Spray (Fog)
Testing, ISO 9227:2012, and employing a 5 % (by weight) salt solution, for 200 h. At the end
of the test, the parts are removed from the chamber, and washed in clean running water not
warmer than 38 °C, to remove salt deposits from the surface. Parts are dried immediately.
Surface corrosion may be cleaned by light brushing, if required, to observe corrosion of the
underlying surface.
Parts are acceptable if, upon completion of the test, they do not show pitting, cracking, or
other deterioration more severe than that resulting from a similar test on passivated
X5CrNI18-9 (ISO name 4301-304-00-I) stainless steel according to ISO 15510:2014.
Exception: an enclosure constructed of X5CrNI18-9 (ISO name 4301-304-00-I) or
X3CrNiMo17-12-3 (ISO name 4436-316-00-I) stainless steel according to ISO 15510:2014 is
not required to be subjected to this test.

• a minimum prospective short circuit current withstand of 16 kA RMS/1 s,
• a maximum rated peak withstand current of 40 kA.
Compliance is checked by testing a socket-outlet and a mating plug with a new
complementary socket-outlet and mating plug complying with this standard, and a ship
connector and a mating ship inlet with a new complementary ship connector and mating ship
inlet complying with this standard.
30 Electromagnetic compatibility
