本报告旨在提供各种航空航天电线和电缆结构的紫外（UV）激光标记和标记对比度测量结果的信息，其中大多数电线和电缆的规范未规定激光标记的具体要求。本文件内容仅供参考和指导。不打算将其用作标记AS5649所涵盖的工艺规范或标准的基础。

The purpose of this report is to provide information on the results of ultraviolet (UV) laser marking and mark contrast measurement of a wide range of aerospace wire and cable constructions, the specifications for most of which do not state specific requirements for laser markability. The contents of this document are for information and guidance only. It is not intended that it be used as the basis for marking process specifications or standards, which are covered by AS5649.
