scope:

This European Standard specifies the required characteristics and test procedures for fire resistant or fireproof electrical cables for use in aircraft electrical systems. These cables should also maintain a specific surface resistance when they are subjected to a flame of 1 100 °C after 5 minutes (fire resistant) or 15 minutes (fire-proof) exposure. They should be rated at an a.c. voltage of 600 V r.m.s., a frequency of maximum 2 000 Hz and a long term temperature of up to 260 °C (ambient temperature plus temperature rise in conductor).
