Cable management systems (CMS) providing support for cables with intrinsic fire resistance

Scope

This document specifies test methods for cable management systems (CMS) intended 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 according to EN 50582 and communication cables according to EN 50289-4-16 are under consideration.
