Introduction

Durability of function-related marking of aircraft electrical cables is of great importance throughout the

life of an aircraft, during initial assembly, operation and maintenance operations in service.

Markings should, therefore, be made to a sufficiently high standard to satisfy requirements initially and

for the remainder of the expected life marked cable or equipment containing it.

Markings are applied by the user to the cable insulation, jacket or sheath and should not degrade the

performance of the cable. They should be applied in accordance with design requirements using a process

approved by the Design Authority.
