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 document includes cable cleats that rely on a mounting surface specified 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 where appropriate. This document does not apply to cable ties.<\/p>\n
