This standard PD CLC/TR 50658:2022 Cable management systems (CMS) providing support for cables with intrinsic fire resistance is classified in these ICS categories:
13.220.50 Fire-resistance of building materials and elements
29.060.20 Cables
91.140.50 Electricity supply systems
This document specifies test methods for cable management systems intended (CMS) to provide support for intrinsic fire-resistant cables in order to determine their abilities to maintain the function of electrical power cables and signal/control cables for a specified duration when subjected to fire under defined conditions. This document establishes a non-hierarchical classification for this ability. Additional devices to fix the cable management systems providing fire resistant support (CMS-support) to the building structure for example screws, anchors etc. are not covered by this document. CMS intended to provide support and fire protection for cables are tested according to EN 1366 11. This document does not apply to powertrack systems. NOTE Rules for testing CMS-support for fibre optic cables and communication cables are under consideration.
