1 Scope
This European Standard specifies reaction to fire performance requirements, test and asssment methods for electric cables ud for the supply of electricity and for control and communication purpos, which are intended for u in construction works and subject to performance requirements
on reaction to fire.
一二八事变
The cables covered by this standard are intended to be ud for the supply of electricity and communications in buildings and other civil engineering works with the objective of limiting the generation and spread of fire and smoke.
Cables intended to be ud for the supply of electricity, communication, and fire detection and alarm in buildings and other civil engineering works where it is esntial 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.
NOTE This European Standard does not replace the electrical, mechanical and environmental requirements that are esntial to demonstrate compliance with other applicable cable standards/specifications.
This European Standard covers:
— power cables – insulated conductors and cables for u in, e.g. the supply of electricity;
— control and communication cables – wires, symmetric cables, and coaxial cables with metallic con
ductors for u in, e.g. telecommunication, data transmission, radio frequency, video communication and signalling and control equipment;
— optical fibre cables – for u in, e.g. telecommunication, data transmission, radio frequency, video communication and signalling and control equipment.

4.1 Reaction to fire
The contribution of power, control and communication cables to the development of fire shall be verified according to the test methods relevant for the claimed class as indicated in Clau 5.
Test results shall be classified according to EN 13501-6.
The contribution to the development of fire is classified regarding gross calorific potential, flame spread, total heat relea, peak heat relea rate and Fire Growth Rate Index (FIGRA) and is completed by additional classifications regarding smoke production, flaming droplets/particles and acidity.
4.2 Relea of dangerous substances
National regulations on dangerous substances may require verification and declaration on relea, and sometimes content, when products covered by this standard are placed on tho markets. In the
