IEC 61914-2021 pdf free download – Cable cleats for electrical installations.
This International Standard specifies requirements and tests for cable cleats used for securingcables in electrical installations and for intermediate restraints used for holding cables togetherin formation in electrical installations. Cable cleats provide resistance to electromechanicalforces where declared.This document includes cable cleats that rely on a mounting surfacespecified by the manufacturer for axial and/or lateral retention of cables.
Various types of cable cleats and intermediate restraints are shown in Annex A.
NOTE Requirements for manufacturers in this document also apply to importers and responsible vendors whereappropriate.
This document does not apply to cable ties.

3.1
cable cleat
device provided with a means of attachment to a mounting surface and that provides securingof cables when installed at intervals along the length of cables
Note 1 to entry: Examples of mounting surfaces that may be specified are ladder, tray, strut(see Figure A.8 ) or rail.Hardware , such as screws or bolts, needed to secure cable cleats to the mounting surface is not necessarily suppliedwith cable cleats.
Note 2 to entry: Some examples of cable cleats are shown in Annex(see Figure A.1 to Figure A.10). Theseexamples do not limit the use of other cable cleat designs that conform to the requirements of this document.
3.2
intermediate restraint
cable retaining device intended to be used with cable cleats，without being attached to amounting surface,to hold cables together in formation and/or to provide resistance toelectromechanical forces
3.3
metallic
consisting of metal only
3.4
non-metallic
consisting of non-metallic material only
3.5
composite
consisting of metallic and non-metallic materials.IEC 61914 pdf download.
