Cables not intended for permanent use in buildings are generally exempt from the requirements of the CPR, for example:
• Patch cables (patch cords)
• Cable systems covered by the Machinery Directive (e.g. lift cables)
• Cables not intended for use in construction works (e.g. outdoor cables)
• Flexible cables to devices, lights or machines
• Cables leading to consumers via connectors
• Safety cables with insulation integrity and/or functional integrity
“Safety cables” are currently exempt from the requirements of the CPR.
According to EN 50575 “Cables intended to be used for the supply of electricity, communication, and fire detection and alarm in buildings and other civil engineering works where it is essential to assure the continuity of power and/or signal supply of safety installations such as alarm, way guidance and fire fighting installations are not covered by this standard.”
Work is under way on the appropriate standards for safety cables with insulation integrity and/or functional integrity (System Circuit Integrity).
