CABLE MANAGEMENT SYSTEMS –
CABLE TIES FOR ELECTRICAL INSTALLATIONS
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 62275 has been prepared by subcommittee 23A: Cable
management systems, of IEC technical committee 23: Electrical accessories.
This third edition cancels and replaces the second edition published in 2013. This edition
constitutes a technical revision.

4 General requirements
A cable tie and a fixing device shall withstand the stresses likely to occur during recom-
mended installation practice and perform under the conditions of classifications in Clause 6 as
declared by the manufacturer.
Compliance is checked by carrying out all the appropriate specified tests.
NOTE Annex A details the compliance checks to be carried out for cable ties and fixing devices currently
complying with IEC 62275:2013 in order to comply with this edition 3.
5 General notes on tests
5.1 Tests according to this document are type tests. Unless otherwise specified, tests are
carried out with the cable ties and their associated fixing devices, where available, installed
as in normal use according to the manufacturer's instructions.
Unless otherwise specified, requirements and tests for fixing devices also apply to adhesive
fixing devices.
NOTE For guidance in determining product types and sample sets, a family of cable ties or fixing devices having
material, construction characteristics, and classifications according to Clause 6, in common, are considered of the
same product type. Examples for consideration are identical generic material description, material colours, or
variable lengths of a cable tie of otherwise similar construction. The sample sets selected for testing from each
product type is representative of the extremes of the range (example: shortest and longest), and the minimum
performance level obtained for either extreme is determined to be representative of the entire range.
Consideration is given to minor construction variations that can be determined by inspection to have no effect on
performance, when determining product types.
5.2 Unless otherwise specified, tests on non-metallic and composite components shall
commence when the samples have been removed from their packaging and then stabilized at
a temperature of (23 ± 5) °C and at a relative humidity of (50 ± 5) %, for a period as indicated
in Table 1.
NOTE This stabilization intends to achieve equilibrium of moisture content for all samples before and after further
conditioning and testing.
Table 1 – Stabilization time for samples
Reference thickness (RT) of device Stabilization time

1,2 < RT ≤ 1,4 21
−7
1,4 < RT

All thicknesses of materials known to 2 ± 1/3
have low hygroscopic characteristics
The reference thickness of a cable tie is measured at the midpoint of the strap. The reference
thickness of a fixing device shall be the smallest cross-section in the area that interfaces with
the cable tie or as declared by the manufacturer. See Figure 1.
When the equilibrium moisture content for a material at (23 ± 5) °C and (50 ± 5) % relative
humidity is determined through a method agreed to by the manufacturer and the testing
laboratory, the stabilization time in Table 1 may be reduced when all of the following
conditions are met:
a) the product's moisture content in the as-received condition and after each appropriate
conditioning is measured using a calibrated moisture analyzer device;
b) the samples are subjected to exposure to a constant temperature not exceeding 50 °C
and a relative humidity not exceeding 80 %; and
c) the product's equilibrium moisture content at (23 ± 5) °C and (50 ± 5) % relative humidity
is verified using a calibrated moisture analyzer device. This verification process is
repeated until equilibrium is determined.

5.3 Unless otherwise specified, the tests shall be carried out at an ambient temperature of
(23 ± 5) °C and with a relative humidity of between 40 % and 60 %.
5.4 Unless otherwise specified, three new samples are submitted to the tests and the
requirements are satisfied if all the tests are met. If only one of the samples does not satisfy a
test owing to an assembly or manufacturing fault, that test and any preceding one which may
have influenced the results of the test shall be repeated. The tests that follow shall be carried
out in the required sequence on another full set of samples, all of which shall comply with the
requirements.
NOTE The applicant, when submitting the first set of samples, can also submit an additional set of samples which
may be necessary if one sample fails. The test station will then without further request test the additional set of
samples and will reject only if a further failure occurs. If the additional set of samples is not submitted at the same
time, a failure of one sample will entail a rejection.
5.5 When toxic or hazardous processes are used, due regard shall be taken of the safety of
persons within the test area.
– 10 – IEC 62275:2018 © IEC 2018
5.6 Unless otherwise specified, the cross-head speed of a tensile machine used during the
tests shall be (25 ± 2,5) mm/min.
5.7 Where required for heat ageing, a full draft circulating-air oven as specified in
IEC 60216-4-1:2006 shall be used. A portion of the air shall be allowed to re-circulate and a
substantial amount of air shall be admitted continuously to maintain the normal air content
surrounding the samples. The oven shall be adjusted to achieve more than five complete
fresh-air changes per hour.
5.8 An integral assembly shall be tested as a complete sample. The integral assembly shall
be subjected to the conditionings for the cable tie prior to conducting the mechanical strength
test for the fixing device in accordance with 9.7.
A fixing device, the performance of which is dependent on the mounting hole size, the
thickness of the material sheet to which it is to be mounted, or the mounting orientation
declared by the manufacturer in accordance with Table 7, shall comply with all applicable
tests when the device is assembled to the minimum and maximum thickness of each mounting
surface, in the largest hole size, and in each intended mounting orientation declared by the
manufacturer. When it can be determined that a particular mounting orientation represents the
most onerous condition, the results of the tests in that orientation may represent all mounting
orientations.
An adhesive fixing device, the performance of which is dependent on the mounting surface or
the mounting orientation, shall comply with all applicable tests when the device is assembled
on the surfaces for which it is intended, and in each intended mounting orientation declared
by the manufacturer. When it can be determined that a mounting orientation represents the
most onerous condition, the results of the tests in that orientation may represent all mounting
orientations.
5.9 Unless otherwise specified, when conducting the tests on cable ties in Clause 9, the
samples shall be installed according to the manufacturer's instructions on a steel or
aluminium mandrel which has a diameter A according to Table 2.
If the minimum declared diameter of the cable tie is greater than the diameter of the test
mandrel specified in Table 2, then a test mandrel that has the minimum diameter as declared
by the manufacturer shall be used.
The width B of the mandrel shall be at least 5 mm greater than the maximum width of the
cable tie as shown in Figure 2.
Table 2 – Test mandrel diameter
Maximum declared Test mandrel diameter
diameter (A)
mm mm
≤ 20 9,5 ± 1
> 20 and ≤ 38 20 ± 2
> 38 38 ± 2
For the loop tensile strength tests, the mandrel shall be split in two equal parts and the cable
ties positioned as shown in Figure 2a).
Cable ties having a parallel entry strap shall be mounted to the mandrel as shown in
Figure 2b).
The excess end (tail) of the cable tie is permitted to be cut off after assembly, except in the
tests where marking is required for the purpose of measurement (see 9.6).
The use of separate steel or aluminium conditioning mandrels is permitted. The conditioning
mandrels need not be split but shall have a diameter approximately equivalent to the
appropriate test mandrel to allow transfer of the sample to the test mandrel. Conditioned
samples shall be carefully transferred to the appropriate test mandrel for carrying out the loop
tensile test. Where it has been determined that the transfer of the samples from the
conditioning mandrel to a test mandrel has influenced the test results, an additional sample
set shall be conditioned and tested.

7 Marking and documentation
7.1 Each cable tie and fixing device shall be marked with:
– the manufacturer's or responsible vendor's name or trademark, and
– an identifying symbol as defined by the manufacturer.
Compliance is checked by inspection
Where it is not possible, for example, due to the small size of a cable tie or fixing device to
mark on it the identifying symbol, then this symbol may be marked on the packaging.
NOTE 1 The identifying symbol can be a reference number, letter, etc.
NOTE 2 Marking can be applied, for example, by moulding, pressing, engraving, printing, adhesive labels, etc.
7.2 Marking on cable ties, fixing devices and integral assemblies shall be legible, durable
and indelible.
Laser marking directly on the product and marking made by moulding, pressing or engraving
are not subjected to this test.
Compliance is checked by inspection, using normal or corrected vision, without additional
magnification.
The test is made by rubbing the marking for 15 s with a piece of cotton cloth soaked with
water and again for 15 s with a piece of cotton cloth soaked with n-hexane 95 % (Chemical
Abstracts Service Registry Number, CAS RN, 110-54-3).
NOTE n-hexane 95 % is available from a variety of chemical suppliers as a high-pressure liquid chromatography
(HPLC) solvent.
When using the liquid specified for the test, precautions as stated in the relative material
safety datasheet provided by the chemical supplier shall be taken to safeguard the laboratory
technicians.
The marking surface to be tested shall be dried after the test with water.
Rubbing shall commence immediately after soaking the piece of cotton, applying a
compression force of (5 ± 1) N at a rate of about one cycle per second (a cycle comprising a
forward and backward movement along the length of the marking). For markings longer than
20 mm, rubbing can be limited to a part of the marking, over a path of at least 20 mm length.
– 16 – IEC 62275:2018 © IEC 2018
The compression force is applied by means of a test piston which is wrapped with cotton
comprising of cotton wool covered by a piece of cotton medical gauze. Test piston is shown in
Figure 3.
The test piston shall have the dimensions shown in Figure 3 and shall be made of an elastic
material that is inert against the test liquids and has a Shore-A hardness of 47 ± 5 (for
example synthetic rubber). When it is not possible to carry out the test on the specimens
owing to the shape/size of the product, a suitable piece having the same characteristics as
the product can be submitted to the test.
