Guidelines for Wire Identification Marking Using the Hot Stamp Process
|Publication Date:||1 December 2016|
These guidelines have been written to provide process information regarding the hot stamp method of marking wire identification directly on aerospace wires and cables.
This document is not intended to encourage the use of hot stamp marking or to endorse the related process. This method of marking wire identification is prohibited on any aerospace vehicle wiring that is required to conform to the provisions of AS50881. Methods which do not deform wire or cable insulation, such as Ink Jet, Dot Matrix or UV Laser marking are encouraged as a means of minimizing the possibility of insulation damage, particularly on insulation constructions of less than 0.010 in wall thickness. AIR5575 provides a comprehensive report on the issue of wire damage than can occur when hot stamp wire marking process is employed.
In recognition that the present use of hot stamp wire marking is in some operations and may continue for an extended period, the guidelines provided in this document are intended to provide process control information necessary to minimize the possibility of insulation damage.
