Aerospace series. Cable, electrical, fire resistant. Technical specification
This document specifies the required characteristics and test procedures for fire resistant or fire-proof 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.
The insulation of these cables is designed to withstand aircraft voltages at a frequency not exceeding 2 000 Hz.
Unless specified by individual product standards, the maximum demonstrated AC voltage rating of these cables is:
They are rated for a long term temperature of up to 260 °C (ambient temperature plus temperature rise in conductor).
