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.

2.3.3 Assembly of cores and fillers, if any
The cores shall be twisted together, where appropriate in several concentric layers.
A centre core is not permitted but a centre filler of suitable material shall be applied for cables
with five or more cores in the first layer. Assemblies with three or more cores shall have one
core which is coloured green and yellow.
Around each layer a tape may be applied which may cover the cores fully or partially. The
tape shall not adhere to the cores.
For two-core cables, the space between the cores shall be filled either by separate fillers or
by the sheath filling the interstices.
2.3.4 Inner sheath for screened cables
The inner sheath shall be a polyvinyl chloride compound of type PVC/ST5 (see IEC 60227-1)
applied around the core assembly. For all cables, the thickness of the inner sheath shall be
determined by the formula:
t = 0,02 D + 0,6 mm,
is f
where D is the fictitious diameter over the laid-up core, calculated in accordance with A.2.1, A.2.2
f
2 2
and A.2.3 of IEC 60502, annex A, and where the fictitious diameter (d ) of 0,5 mm , 0,75 mm and
l
2
1,0 mm conductors (not given in A.2.1) shall be taken to be 0,8 mm, 1,0 mm and 1,1 mm,
respectively.
For cables with the preferred number of cores, the calculated values of the inner sheath
thickness are given in column 3 of table 1.
NOTE In the case of cables comprising 10 or more cores, the values specified apply to a core assembly in two or
more layers.
The mean value of the thickness of the sheath shall be not less that the calculated value.
However, the thickness at any place may be less than the calculated value provided that the
difference does not exceed 0,1 mm + 15 % of the calculated value.
The inner sheath may fill the interstices of the laid-up core assemby, but it shall not adhere
to the cores.
2.3.5 Screen
For screened cables, the screen shall be applied over the inner sheath, in the form of a braid
of plain or tinned copper wires.
For cables with the preferred number of cores, the diameter of the copper wires shall comply
with the values given in column 4 of table 1.
For the other cables, the following maximum values apply:
– 0,16 mm for d ≤10,0 mm
– 0,21 mm for 10,0 mm – 0,26 mm for 20,0 mm – 0,31 mm for d >30,0 mm
where d is the fictitious diameter under the braid which is calculated by adding to the fictitious
diameter over laid-up cores, twice the specified thickness of inner sheath.

---------------------- Page: 9 ----------------------
– 8 – 60227-7  IEC:1995+A1:2003+A2:2011
The screening efficiency shall be determined by measuring the transfer impedance. The value
obtained shall not exceed 250 Ω/km at 30 MHz.
2.3.6 Sheath or oversheath
The sheath or oversheath shall be polyvinyl chloride compound of type PVC/ST9
(see IEC 60227-1) applied either:
– as an oversheath around the screen of screened cables, or
– as an sheath around the laid-up cores of unscreened cables.
An optional tape may be applied between screen and oversheath.
For all cables the thickness or the sheath or oversheath shall be determined by the formula:
t = 0,08 d + 0,4 mm
s L
with a maximum value of 2,4 mm, where d is the fictitious diameter over the screen of the
L
screened cables or over the laid-up core assembly of unscreened cables.
The fictitious diameter shall be calculated in accordance with IEC 60502-1, annex A and 2.3.4
of this standard. The increase in diameter due to the braided screen is four times the diameter
of the braiding wire specified in column 4 of table 1.
For cables with the preferred numbers of cores, the calculated values of the sheath and over-
sheath thickness are given in column 5 of table 1 and in column 3 of table 2 (see note in 2.3.4).
Both for sheath and oversheath, the thickness requirements apply as specified in 5.5.3 of
IEC 60227-1.
In unscreened cables, the sheath may fill the interstices of the laid-up core assembly, but it
shall not adhere to the cores. In screened cables, the oversheath shall fit closely but not
adhere to the screen.
All cables shall have practically a circular cross-section.
2.3.7 Core identification
Except the green and yellow core, if any, all cores shall be identified by numbers in
accordance with 4.2 of IEC 60227-1.
2.3.8 Overall diameter
The mean overall diameter of the cables shall be within the limits to be determined
in accordance with IEC 60719. For cables with the preferred number of cores, the limits,
according to IEC 60719 are given in columns 6 and 7 of table 1 or in columns 4 and 5 of table 2,
(see note in 2.3.4).
2.4 Tests
Compliance with the requirements of 2.3 shall be checked by inspection and by the tests
given in table 3.

2.5 Guide to use
The main purpose of these cables is for the interconnection of parts of machines used for
manufacturing purposes, including machine tools and mechanical handling equipment.
The cables are permitted for the direct connection to the mains. Continual flexing is not
recommended for the screened cables. If any of these cables is not required to move during
use, installation in conduits, trunking etc. is advised.
Screened cables are recommended in environments where a moderate level of electro-
magnetic interference is encountered.
These cables are designed for use only inside buildings and where the ambient temperatures
remain within the range of +5 °C to +40 °C.
Maximum rated conductor temperature in normal use: 70 °C.
Maximum sheath temperature: 60 °C.
