31、EMS AND CABLE LADDER SYSTEMS FOR CABLE MANAGEMENT 1 Scope This International Standard specifies requirements and tests for cable tray systems and cable ladder systems intended for the support and accommodation of cables and possibly other electrical equipment in electrical and/or communication syste
32、ms installations. Where necessary, cable tray systems and cable ladder systems may be used for the segregation of cables. This standard does not apply to conduit systems, cable trunking systems and cable ducting systems or any current-carrying parts. NOTE Cable tray systems and cable ladder systems
33、are designed for use as supports for cables and not as enclosures. 2 Normative references The following normative documents contain provisions, which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of
