CPR/Fire-safety cable
CPR Introduction
2. The reference standard for cables.
The basic reference standard for cables and their performance with respect to fire under
the CPR is: EN 50575:2014 + A1:2016: Power, control and communication cables (cables for general applications in construction works subject to reaction to fire requirements).
The standard specifies reaction to fire requirements, including test and assessment methods,
and addresses requirements for release of dangerous substances. Furthermore, it specifies requirements for type testing, Factory Production Control (FPC), and which system shall be used for Assessment and Verification of Constancy of Performance (AVCP).
Currently it only relates to the way cables react to fire not the way they resist fire (continue to operate in a fire). Therefore this relates to those cables that are NOT designed to resist fire. This includes PVC and LSHF armoured, flat twin and earth and single core, and many others including data and optical cables. If they’re fixed into the fabric of the building they are in scope. Appliance power flexes aren’t in scope, or those just buried in the ground and not entering a building.
