Cable cleats for electrical installations (IEC 61914:2021)
This International Standard specifies requirements and tests for cable cleats used for securing cables in electrical installations and for intermediate restraints used for holding cables together in formation in electrical installations. Cable cleats provide resistance to electromechanical forces where declared. This standard includes cable cleats that rely on a mounting surface specified by the manufacturer for axial and/or lateral retention of cables.
NOTE Requirements for manufacturers in this document also apply to importers and responsible vendors where appropriate.
This standard does not apply to cable ties.

L'IEC 61914:2021 spécifie les exigences et les essais relatifs aux brides de câbles utilisées pour la fixation des câbles dans les installations électriques et aux dispositifs intermédiaires de tenue utilisés pour le maintien des câbles en formation dans des installations électriques. Les brides de câbles fournissent une résistance aux forces électromécaniques lorsque cela est déclaré. Le présent document inclut les brides de câbles qui reposent sur une surface de montage spécifiée par le fabricant pour le maintien axial et/ou latéral des câbles.
Cette troisième édition annule et remplace la deuxième édition parue en 2015. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- rationalisation des exigences relatives aux mandrins d’essai, détaillées dans la section Généralités sur les essais (Article 5);
- ajout de la définition de la fourrure et définition des exigences d’essai dans lesquelles les fourrures et autres accessoires sont utilisés;
- ajout des définitions BT, MT et HT pour les câbles et définition des exigences d'essai en cas d'utilisation de câbles MT et HT;
- ajout de nouvelles classes de tenue à la corrosion pour les produits revêtus;
- ajout de nouvelles exigences et d'un essai de durabilité et de lisibilité des marquages;
- ajout de nouvelles exigences d'essai pour les essais de tenue à la charge axiale des brides pour plusieurs câbles;
- ajout d’exigences d’essai de tenue à la charge latérale pour les dispositifs intermédiaires de tenue.
Kabelske objemke za elektroinštalacije (IEC 61914:2021)
Ta mednarodni standard določa zahteve in preskuse za kabelske objemke, ki se uporabljajo za pritrditev kablov v električnih inštalacijah, ter vmesne naslone, ki se uporabljajo za ohranjanje formacije kablov v električnih inštalacijah. Kabelske objemke zagotavljajo odpornost na morebitne elektromehanske sile. Ta standard vključuje kabelske objemke za montažo na površino, na katero se po navedbah proizvajalca lahko pritrdi kable po osi in/ali bočno.
OPOMBA: Zahteve za proizvajalce v tem dokumentu veljajo tudi za uvoznike in odgovorne prodajalce, kadar je primerno.
Ta standard se ne uporablja za kabelske spojke.

CABLE CLEATS 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.
IEC 61914 has been prepared by subcommittee 23A: Cable management systems, of IEC
technical committee 23: Electrical accessories. It is an International Standard.
This third edition cancels and replaces the second edition published in 2015. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) requirements for mandrels used in testing rationalised and detailed in the general test
requirements (Clause 5);
b) definition of liner added and test requirements where liners and other optional parts are
used;
c) definitions for LV, MV and HV cables added and test requirements where MV & HV cable
are used ;
d) new corrosion resistance classes for plated products added;
e) new requirements and test for durability and legibility of markings added;
f) new test requirements for axial load testing of cleats for more than one cable added;
