INTRODUCTION
This part of IEC 62613 has been primarily written to address the needs of IEC/IEEE 80005-1
in terms of plugs, socket-outlets, ship connectors and ship inlets (hereafter referred to as
"accessories"), to deliver electrical power to ships in ports. The purpose of IEC/IEEE 80005-1
is to define requirements that allow compliant ships to connect to compliant high-voltage
shore power supplies through a compatible shore-to-ship connection.
These ships are described in IEC/IEEE 80005-1.
Ships that do not require connecting with standardized high-voltage shore power sup p l i e s a s
above may use accessories that are not covered by the standard sheets of IEC 62613-2, but
they may find it impossible to connect to these shore supplies.
Low-voltage plugs, socket-outlets, ship connectors and ship inlets used for the conn e c t i o n o f
certain ship types to low-voltage shore power supplies can be found in IEC 60309 (all parts).

4 General
4.1 Ge ne ral re quirements
Accessories shall be supplied with all the necessary instructions from the m a n u fa c t u r e r , for
example on installation, assembling, wiring, commissioning, inspection, preventive
maintenance, replacement of consumable parts, etc., including the levels of ability of the
personnel to perform such operations.
Accessories shall be so designed and constructed that in nor m a l u s e t h e i r p e r fo r m a n c e i s
reliable and without danger to the user or the surroundings.
Accessories constructed in accordance with this document shall be suitable for the
environment conditions in the space(s) where they are intended to operate. Accessories
located on ships shall comply with the applicable part(s) of IEC 60092.
Unless otherwise stated, the normal use environment in which the accessories complying with
this document are normally used is pollution degree 3 according to IEC 60664-1.
Accessories shall comply with the applicable requirements of IEC 60502-4.
Accessories shall be wired, installed, commissioned, maintained and used by electrically
instructed or skilled personnel.
HVSC systems do not allow in-line connections unless a specific piece of e q u i p e m e n t m a d e
for that purpose is used. It shall not be possible to connect a plug into a ship connector
(see 8.4).
4.2 Ge ne ral note s on te sts
4.2.1 Tests according to this document are type tests. If a part of an accessory has
previously passed tests for a given degree of severity, the relevant type tests shall not be
repeated if the severity is not greater.
4.2.2 Unless otherwise specified, the samples are tested as deliver e d a n d u n d e r n o r m a l
conditions of use, at an ambient temperature of (20 ± 5) °C; the tests are made at rated
frequency.
4.2.3 Unless otherwise specified, the tests are carried out in the or der of t he c l aus es or
subclauses of this document.
4.2.4 Three samples are subjected to all the tests . For the tests of 11.1.4, for t h e t e s t s o f
19.6 and 19.7, and for the tests of Clause 27, a new set of three samples can be used, if
necessary.
4.2.5 Accessories are deemed to comply with this document if no sample fails in the
complete series of appropriate tests. If one sample fails in a test, that test and those
preceding which can have influenced the test result are repeated on another set of three
samples, all of which shall then pass the repeated tests.
NOTE In general, only the test that caused the failure will be repeated, unless the sample fails in one of the tests
of Clause 21 in which case the tests are repeated from that of Clause 20 onwards.
The applicant can submit, together with the first set of samples, the additional set, which could be necessary if one
sample f ails. The testing station will then, without further request, test the additional samples and will reject only if
a f urther failure occurs. If the additional set of samples is not submitted at the same time, the failure of one sample
w ill entail a rejection.

socket-outlets or ship connectors, or between ship inlets and ship connectors. It s hal l not be
possible to make single-pole connections between single-pole and multi-pole accessories.
Improper connections include single-pole connections and other c onnec t i ons whi c h do not
comply with the requirements for protection against electric shock.
Compliance is checked b y inspection.
8.4 It shall not be possible to engage plugs into ship connectors, as in-line cable
connections (cable couplers) are not allowed by the application.
Compliance is checked b y inspection and test.
9 Protection against e lectric shock
9.1 Accessories shall be so designed that live parts of socket-outlets and ship connectors,
when they are wired as in normal use, and live parts of plugs and ship inlets, when they are in
partial or complete engagement with the complementary accessories, are not accessible
(IP2X according to IEC 60529).
Pilot contacts can be accessible if used at an extra low voltage.
NOTE The neutral contact and pilot contacts of socket-outlets and ship connectors are deemed to be l i ve p art s.
Pilot contacts are deemed not to be live parts if used at extra low voltage.
In addition, it shall not be possible to make contact between a contact of a plug o r s h i p i n l e t
and a contact of a socket-outlet or ship connector while any contact is accessible.
Compliance is checked b y inspection and, if necessary, b y a test on the s a m p l e wi r e d a s i n
