WITHDRAWN IEC 61914:2015 | Cable Cleats For Electrical Installations

Published 11 May 2022

Cable Cleats

This article is intended to highlight IEC standard and specification updates in relation to short-circuit testing and purchasing of cable cleats.

The previous ‘second edition’ of IEC 61914:2015 has now been withdrawn and replaced with IEC 61914:2021 – the third edition of the standard. This edition constitutes a technical revision of which we will detail below. 

All cable cleats distributed by Thorne & Derrick are currently undergoing testing procedures to conform to the latest IEC 61914:2021 standards. Certification will be in place before the deadline.

So What’s Changed?

IEC 61914:2015 Is Withdrawn

The new standard is available as IEC 61914:2021 CMV which contains the International Standard and its commented version, providing a quick and easy way to compare all of the changes between IEC 61914:2021 edition 3.0 and the previous IEC 61914:2015 edition 2.0. View the document here.

IEC 61914:2021 specifies requirements and tests for cable cleats and intermediate restraints used for securing cable in electrical installations. Cable cleats provide resistance to electromechanical forces where declared. This document includes cable cleats that rely on a mounting surface specified by the manufacturer for axial and/or lateral retention of cables.

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;

g) Lateral load test requirements for intermediate restraints added

“Cable cleats are critical electrical safety products – in the event of a short circuit they can protect your people, not just plant. During a recent tender bid we were alerted to non-conformance of a competitor product during the technical qualification procedure for a major UK infrastructure project. Simply, their product was tested to the cancelled 2009, not superseding 2015 version. Thorne & Derrick distribute LV HV Cable Accessories & Electrical Equipment from market-leading manufacturers tested to the current range of international standards,” comments Chris Dodds (Sales Manager at Thorne & Derrick).

“The closest example I can think of for this is car seat belts. If you were on the market to purchase a car and were advised that the seatbelts on the car you had chosen were not compliant to the latest industry standards, you may decide against purchasing that car due to safety concerns. Moreover the car would not be safe for sale in UK or European markets and would not bear the required UK CA or CE mark. Cable cleats for cables can be viewed in a similar way to seatbelts in cars as they both perform safety functions, adds Noman Shabir (National Sales Manager at Ellis Patents).
