95 CABLE TIES FOR ELECTRICAL INSTALLATIONS
97 FOREWORD
98 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
99 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
100 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
101 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
102 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC
103 Publication(s)"). Their preparation is entrusted to technical committees; any IEC National Committee interested
104 in the subject dealt with may participate in this preparatory work. International, governmental and non-
105 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
106 with the International Organization for Standardization (ISO) in accordance with conditions determined by
107 agreement between the two organizations.
108 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
109 consensus of opinion on the relevant subjects since each technical committee has representation from all
110 interested IEC National Committees.
111 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
112 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
113 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
114 misinterpretation by any end user.
115 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
116 transparently to the maximum extent possible in their national and regional publications. Any divergence
117 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
118 the latter.
119 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
120 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
121 services carried out by independent certification bodies.
122 6) All users should ensure that they have the latest edition of this publication.
123 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
124 members of its technical committees and IEC National Committees for any personal injury, property damage or
125 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
126 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
127 Publications.
128 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
129 indispensable for the correct application of this publication.
130 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
131 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
132 International Standard IEC 62275 has been prepared by subcommittee 23A: Cable
133 management systems, of IEC technical committee 23: Electrical accessories.
134 This fourth edition cancels and replaces the third edition published in 2018. This edition

276 4 General requirements
277 A cable tie and a fixing device shall withstand the stresses likely to occur during recom-
278 mended installation practice and perform under the conditions of classifications in Clause 6 as
279 declared by the manufacturer.
280 Compliance is checked by carrying out all the appropriate specified tests.
281 NOTE Annex A details the compliance checks to be carried out for cable ties and fixing devices currently
282 complying with IEC 62275:2013 in order to comply with this edition 4.
283 5 General notes on tests
284 5.1 Tests according to this document are type tests. Unless otherwise specified, tests are
285 carried out with the cable ties and their associated fixing devices, where available, installed
286 as in normal use according to the manufacturer's instructions.
287 Unless otherwise specified, requirements and tests for fixing devices also apply to adhesive
288 fixing devices.
289 NOTE For guidance in determining product types and sample sets, a family of cable ties or fixing devices having
290 material, construction characteristics, and classifications according to Clause 6, in common, are considered of the
291 same product type. Examples for consideration are identical generic material description, material colours, or
292 variable lengths of a cable tie of otherwise similar construction. The sample sets selected for testing from each
293 product type is representative of the extremes of the range (example: shortest and longest), and the minimum
294 performance level obtained for either extreme is determined to be representative of the entire range. Consideration
295 is given to minor construction variations that can be determined by inspection to have no effect on performance,
296 when determining product types.
297 5.2 Unless otherwise specified, tests on non-metallic and composite components shall
298 commence when the samples have been removed from their packaging and then stabilized at
299 a temperature of (23 5) °C and at a relative humidity of (50 5) %, for a period as indicated
300 in Table 1.
301 NOTE This stabilization intends to achieve equilibrium of moisture content for all samples before and after further
302 conditioning and testing.

311 5.3 Unless otherwise specified, the tests shall be carried out at an ambient temperature of
312 (23 5) °C and with a relative humidity of between 40 % and 60 %.
313 5.4 Unless otherwise specified, three new samples are submitted to the tests and the
314 requirements are satisfied if all the tests are met. If only one of the samples does not satisfy a
315 test owing to an assembly or manufacturing fault, that test and any preceding one which may
316 have influenced the results of the test shall be repeated. The tests that follow shall be carried
317 out in the required sequence on another full set of samples, all of which shall comply with the
318 requirements.
319 NOTE The applicant, when submitting the first set of samples, can also submit an additional set of samples which
320 may be necessary if one sample fails. The test station will then without further request test the additional set of
321 samples and will reject only if a further failure occurs. If the additional set of samples is not submitted at the same
322 time, a failure of one sample will entail a rejection.
323 5.5 When toxic or hazardous processes are used, due regard shall be taken of the safety of
324 persons within the test area.

325 5.6 Unless otherwise specified, the cross-head speed of a tensile machine used during the
326 tests shall be (25 2,5) mm/min. Dead weights can be used for conducting loop tensile
327 strength tests for cable ties and integral devices classified according to 6.2.3, provided that
328 no sudden application of force occurs.
329 5.7 Where required for heat ageing, a full draft circulating-air oven as specified in
330 IEC 60216-4-1:2006 shall be used. A portion of the air shall be allowed to re-circulate and a
331 substantial amount of air shall be admitted continuously to maintain the normal air content
332 surrounding the samples. The oven shall be adjusted to achieve more than five complete
333 fresh-air changes per hour.
334 5.8 An integral device shall be tested as a complete sample. The integral device shall be
335 subjected to the conditionings for the cable tie prior to conducting the mechanical strength
336 test for the fixing device in accordance with 9.7.
337 A fixing device, the performance of which is dependent on the mounting hole size, the
338 thickness of the material sheet to which it is to be mounted, or the mounting orientation
339 declared by the manufacturer in accordance with Table 6, shall comply with all applicable
340 tests when the device is assembled to the minimum and maximum thickness of each mounting
341 surface, in the largest hole size, and in each intended mounting orientation declared by the
342 manufacturer. When it can be determined that a particular mounting orientation represents the
343 most onerous condition, the results of the tests in that orientation may represent all mounting
344 orientations.
345 An adhesive fixing device, the performance of which is dependent on the mounting surface or
346 the mounting orientation, shall comply with all applicable tests when the device is assembled
347 on the surfaces for which it is intended, and in each intended mounting orientation declared
348 by the manufacturer. When it can be determined that a particular mounting orientation
349 represents the most onerous condition, the results of the tests in that orientation may
350 represent all mounting orientations.
351 5.9 Unless otherwise specified, when conducting the tests on cable ties in Clause 9, the
352 samples shall be installed according to the manufacturer's instructions on a steel or
353 aluminium mandrel which has a diameter A according to Table 2.
354 If the minimum declared diameter of the cable tie is greater than the diameter of the test
355 mandrel specified in Table 2, then a test mandrel that has the minimum diameter as declared
356 by the manufacturer shall be used.
357 The width B of the mandrel shall be at least 5 mm greater than the maximum width of the
358 cable tie as shown in Figure 2.

361 For the loop tensile strength tests, the mandrel shall be split in two equal parts.
362 A metallic cable tie having a parallel entry strap shall be mounted to the mandrel as shown in
363 Figure 2a. Non-metallic or composite cable ties having a parallel entry strap shall be mounted
364 to the mandrel as shown in Figure 2b.

365 The excess end (tail) of the cable tie is permitted to be cut off after assembly, except in the
366 tests where marking is required for the purpose of measurement (see 9.6).
367 The use of separate steel or aluminium conditioning mandrels is permitted. The conditioning
368 mandrels need not be split but shall have a diameter approximately equivalent to the
369 appropriate test mandrel to allow transfer of the sample to the test mandrel. Conditioned
370 samples shall be carefully transferred to the appropriate test mandrel for carrying out the loop
371 tensile test. Where it has been determined that the transfer of the samples from the
372 conditioning mandrel to a test mandrel has influenced the test results, an additional sample
373 set shall be conditioned and tested.
374 For integral devices, when it is determined impractical to condition the samples mounted to a
375 rigid support, samples shall be conditioned separately. When conditioning separately, they
376 shall be installed on a solid mandrel of similar size to the test fixture and the entire sample set
377 may be installed on the same mandrel. After conditioning, each sample shall be mounted to
378 the rigid support test fixture prior to the appropriate tensile pull. Where it has been determined
379 that the transfer of the samples from the conditioning mandrel to a test mandrel has
380 influenced the test results, an additional sample set shall be conditioned and tested.

478 7.1 Each cable tie and fixing device shall be marked with:
479 – the manufacturer's or responsible vendor's name or trademark, and
480 – an identifying symbol as defined by the manufacturer.
481 Compliance is checked by inspection.
482 Where it is not possible, for example, due to the small size of a cable tie or fixing device to
483 mark on it the identifying symbol, then this symbol may be marked on the packaging.
484 NOTE 1 The identifying symbol can be a reference number, letter, etc.
485 NOTE 2 Marking can be applied, for example, by moulding, pressing, engraving, printing, adhesive labels, etc.
486 7.2 Marking on cable ties, fixing devices and integral devices shall be legible, durable and
487 indelible.
488 Laser marking directly on the product and marking made by moulding, pressing or engraving
489 are not subjected to this test.
490 Compliance is checked by inspection, using normal or corrected vision, without additional
491 magnification.
492 The test is made by rubbing the marking for 15 s with a piece of cotton cloth soaked with
493 water and again for 15 s with a piece of cotton cloth soaked with n-hexane 95 % (Chemical
494 Abstracts Service Registry Number, CAS RN, 110-54-3).
495 NOTE n-hexane 95 % is available from a variety of chemical suppliers as a high-pressure liquid chromatography
496 (HPLC) solvent.
497 When using the liquid specified for the test, precautions as stated in the relative material
498 safety datasheet provided by the chemical supplier shall be taken to safeguard the laboratory
499 technicians.
500 The marking surface to be tested shall be dried after the test with water.
501 Rubbing shall commence immediately after soaking the piece of cotton, applying a
502 compression force of (5 ± 1) N at a rate of about one cycle per second (a cycle comprising a
503 forward and backward movement along the length of the marking). For markings longer than
504 20 mm, rubbing can be limited to a part of the marking, over a path of at least 20 mm length.
oSIST prEN IEC 62275:2022
IEC CDV 62275 © IEC 2021 16 23A/994/CDV
505 The compression force is applied by means of a test piston which is wrapped with cotton
506 comprising of cotton wool covered by a piece of cotton medical gauze. Test piston is shown in
507 Figure 3.
508 The test piston shall have the dimensions shown in Figure 3 and shall be made of an elastic
509 material that is inert against the test liquids and has a Shore-A hardness of 47 ± 5 (for
510 example synthetic rubber). When it is not possible to carry out the test on the specimens
511 owing to the shape/size of the product, a suitable piece having the same characteristics as
512 the product can be submitted to the test.
