This document specifies the characteristics of UV laser printable jacket, nickel plated copper conductor, electrical cables Crosslinked Ethylene Tetra Fluoro Ethylene co-polymer XLETFE family for use in the onboard electrical systems of aircraft at operating temperatures between - 65 °C and 150 °C, operating at voltages not exceeding 600 V. This insulation system has been used in aerospace applications using 115 V (phase-to-neutral) 400 Hz ac and 28 Vdc. Verification of the suitability of cables for use in other electrical systems is the responsibility of the user.

These cables are suitable for airframe use without additional protection.

In case of conflict between this standard and other referenced documents the requirements of this standard shall take precedence.
