1 Scope
This document specifies the required characteristics and test procedures for fire
resistant or fire proof electrical cables for use in aircraft electrical systems.
They shall be operated at a rated AC voltage of 600 V ac, a frequency of maximum 2 000 Hz
and a long term temperature of up to 260 °C (ambient temperature plus temperatures
rise in conductor).
These cables shall also maintain a specific dielectric strength when they are subjected
to a flame of 1 100 °C after five (5) minutes (fire resistant) or 15 minutes (fire
proof) exposure.
