INDUSTRIAL CABLE REELS
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61316 has been prepared by subcommittee 23H: Industrial plugs
and socket-outlets, of IEC technical committee 23: Electrical accessories.
This second edition cancels and replaces the first edition, published in 1994, and constitutes
a technical revision.
This standard shall be used in conjunction with IEC 60309-1.
The text of this standard is based on the following documents:
FDIS Report on voting
23H/93/FDIS 23H/94/RVD

This clause of IEC 60309-1 is applicable except as follows:
8.1 Addition:
The surface on which the cable is wound shall be at least eight times the maximum diameter
of the cable as given in IEC 60245-4, as appropriate.
For cable reels using flat cable, the surface on which the cable is wound shall have a
diameter of at least 10 times the average of the upper and lower dimensions of the cable.
8.2 This subclause of IEC 60309-1 is not applicable.
8.3 This subclause of IEC 60309-1 is not applicable.
9 Protection against electric shock
This clause of IEC 60309-1 is applicable except as follows:
Replacement:
9.1
Cable reels shall be designed so that live parts are not accessible when the cable reel is in
normal use and when parts which can be removed without the aid of a tool, have been
removed.
Compliance is checked by inspection and, if necessary, by the tests of 9.1.1 and 9.1.2.
These tests shall be made immediately after the cable reel has passed a current having a
value corresponding to the maximum load, when fully reeled, for 1 h at an ambient
temperature of 20 °C ± 5 °C.
9.1.1 The standard test finger shown in figure 2 of IEC 60309-1 is applied with a force of
10 N ± 1 N in every possible position; an electrical indicator with a voltage not less than 40 V
and not more than 50 V is used to show contact with the relevant part.
For cable reels, where the use of elastomeric or thermoplastic material is likely to
influence compliance with the requirement, the test is repeated but at an ambient temperature
of 35 °C ± 2 °C, the cable reels being at this temperature.
During this additional test, the parts of elastomeric or thermoplastic material of the cable reel
are subjected for 1 min to a force of 75 N, applied through the tip of a straight unjointed test
finger of the same dimensions as the standard test finger. This finger, with an electrical
indicator as described above, is applied to all places where yielding of the insulating material
could impair the safety of the cable reel.

---------------------- Page: 12 ----------------------

61316 © IEC:1999 – 23 –
During this test, the cable reel shall not deform to such an extent that those dimensions which
ensure safety are unduly altered and no live part shall be accessible.
9.1.2 The test is made with a straight rigid steel wire of 1±0,015 mm, applied with a force of
+0,1
(1 ) N. The end of the wire shall be free from burrs and be at right angles to its length.
0
NOTE – This test does not apply to the accessories fitted to the cable reel.
The protection is satisfactory if the wire cannot enter the enclosure, or if it enters, it does not
touch live parts inside the enclosure.
The test wire is provided with an electrical indicator, with a voltage not less than 40 V and not
more than 50 V, to show contact with relevant part.
9.4 Addition:
Parts providing protection against electric shock shall have adequate mechanical strength and
shall be reliably secured by means of screws or in a similar reliable manner so that they will
not work loose in normal use.
Compliance is checked by inspection and by the tests of clauses 24 and 25.
10 Provision for earthing
10.1 For rewireable cable reels having accessible metal parts insulated from live parts by
basic insulation only:
– the earthing terminal shall comply with the requirements of clause 11;
– the earthing terminal shall be located in proximity to the terminals for current-carrying
conductors;
– internal connections between the earthing terminal and accessible metal parts shall be
independent of the connection of the flexible cable in order to prevent loosening of internal
connections during the replacement of flexible cable;
– when terminals of live conductors are accessible, any additional dismantling shall not
be necessary to reach the earthing terminal. Moreover, the earthing terminal shall not be
more than 50 mm distance from the other terminals.
10.2 Corrosion resistance of earth terminal
All parts of the earthing terminal shall be such that there is no risk of corrosion resulting from
contact between these parts and the copper of the earthing conductor, or any other metal that
is in contact with these parts.
The body of the earthing terminal shall be of brass or other metal no less resistant to
corrosion, unless it is a part of the metal frame or enclosure, when the screw or nut shall be of
brass or plated steel complying with clause 25, or other metal no less resistant to corrosion.
10.3 Corrosion resistance of screws and nuts
Screws and nuts of plated steel withstanding the test of clause 25 are considered to be of a
metal no less resistant to corrosion than brass.
Compliance with the requirements of 10.1 to 10.3 is checked by inspection.

---------------------- Page: 13 ----------------------

61316 © IEC:1999 – 25 –
10.4 Earth connections
Accessible metal parts which may become live in the event of an insulation fault shall be
permanently and reliably connected to the earthing terminal or termination.
NOTE 1 – For the purpose of this standard screws and the like for fixing bases or covers are not deemed to be
parts which may become live in the event of a fault.
NOTE 2 – If accessible metal parts are screened from live parts by metal parts which are connected to the earthing
terminal or termination, or if they are separated from live parts by double insulation or reinforced insulation, they
are not, for the purpose of this requirement, regarded as likely to become live in the event of an insulation fault.
Compliance is checked by inspection and by the following test:
A current of 25 A derived from an a.c. source having a no-load voltage not exceeding 12 V is
passed between the earthing terminal and each of the accessible metal parts in turn.
The voltage drop between the earthing terminal and the accessible metal part is measured,
and the resistance calculated from the current and this voltage drop.
In no case shall the resistance exceed 0,05 Ω.
NOTE 3 – Care should be taken that the contact resistance between the measuring probe and the metal part under
test does not influence the test results.
10.5 The earth connection shall be effectively ensured under all conditions which may occur
in normal use, including loosening of fixing screws for covers, careless mounting of the cover
or the like.
Compliance is checked by inspection.
10.6 Earthing terminals intended for the connection of flexible external conductors shall be
designed with ample space for slack of the earthing conductor in such a way that, if the strain
relief should fail, the connection of the earthing conductor is subjected to strain after
connection of the current-carrying conductors and that, in case of excessive stresses, the
earthing conductor will not break before the current-carrying conductors break.
Compliance is checked by the following test:
The flexible cable is connected to the cable reels in such a way that the current-carrying
conductors are led from the strain relief to the corresponding terminals along the shortest
possible path. After they are correctly connected, the core of the earthing conductor is led to
its terminal and cut off at a distance 8 mm longer than necessary for its correct connections.
The earthing conductor is then connected to its terminal. It shall then be possible to house
the loop, which is formed by the protective conductor owing to its surplus length, freely in the
wiring space without squeezing or pressing the core when the cover of the cable reel is put on
again and fixed correctly.
10.7 The internal earthing circuit in cable reels including any joints, contacts and the like
shall be of low electrical resistance.
Compliance is checked by the following measurement which is made after the test specified in
clause 24.

---------------------- Page: 14 ----------------------

61316 © IEC:1999 – 27 –
A current derived from an a.c. source, having a no-load voltage not exceeding 12 V, and
equal to 1,5 times the rated current of the cable reel or 25 A, whichever is the greater, is
passed through the earthing circuit.
The voltage drop is measured and the resistance calculated from the current and this voltage
drop.
In no case shall the resistance exceed 0,05 Ω.
10.8 Internal moveable earth connections of cable reels, e.g. slip rings, shall be as follows:
10.8.1 Moveable earth connections between the terminal for the earthing conductor of the
incoming cable and the earthing terminal for the outgoing cable, or that of the socket outlet,
shall be duplicated. One of these connections shall be a slip ring or an equally effective
contact, while the other connection may be a ball-bearing, a plain bearing, or the like,
provided it is metallic.
10.8.2 Moveable earth
...
