Hot-stamp Marking on Wire & Cable

ARP5369

Guidelines for Wire Identification Marking Using the Hot Stamp Process (STABILIZED: December 2016)

SAE ARP5369B (ARP5369 Revision B), contains 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 may be prohibited on any aerospace vehicle wiring that is required to conform to the provisions of MIL-W-5088 L or AS 50881. 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. In recognition that the present use of hot stamp wire marking is widespread 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.

Rationale: Hotstamp marking is no longer authorized for aircraft applications. Users are referred to AIR5575 for guidance and AS50881 for aircraft marking requirements.
