scope:

This standard specifies requirements for airframe wires and cables in temperature category 135°C, with medium and thin wall insulation. This insulation system has been tested for use in aerospace applications using 115 volts (phase to neutral), 400 hertz ac and 28 volts dc. Verification of the suitability of this product for use in other electrical system configuration levels is the responsibility of the user.

These wires and cables are suitable for fixed wiring at temperatures from 135°C maximum down to minus 75°C but are not suitable for severe flexing at temperatures below minus 40°C.

These wires and cables do not support combustion and will withstand contamination by ester based lubricants and by ester based hydraulic fluids.

The thick wall insulated wires and cables, types 2 and 3, are normally available where dimensional replacements for those wires and cables listed in BS 2G 221 are required for wiring without further protection.

The thin wall insulated wires and cables, types 8 and 9, are intended for internal wiring of equipment.
