本SAE航空航天推荐规程（ARP）旨在提供电线和电缆绝缘标记的建议，以满足易读性要求。此信息是通用信息，适用于任何类型的电线标记系统，例如紫外线（UV）激光标记系统或喷墨或其他基于墨水的电线标记系统。该ARP仅限于人类可读字符的易读性，不涉及条形码或其他机器可读符号。在本ARP中，除单独的电线外，电线一词还指护套电缆和光纤电缆。 本ARP定义了影响接线标记易读性的因素。影响易读性的变量有两种:刺激变量和环境变量。刺激变量是那些与标记本身有关的因素。本ARP为有助于易读性的关键刺激变量建立了一套指南，在指定和使用导线标记设备的过程中应将其考虑在内。环境变量影响标记的阅读，例如照明、观察者刺激距离、观察者对刺激的方向、杂波、观察者的视力、精神状态和视觉暴露持续时间。

The purpose of this SAE Aerospace Recommended Practice (ARP) is to provide recommendations for marking wire and cable insulations to meet legibility requirements. This information is generic and applies to any type of wire marking system, such as an ultraviolet (UV) laser marking system or an inkjet or other ink based wire marking system. This ARP is limited to the legibility of human-readable characters and does not address bar code or other machine-readable symbols. In this ARP, the term wire refers to jacketed cables and fiber optic cables in addition to individual wires.This ARP defines the factors that affect the legibility of markings on wiring. Two generic types of variables affect legibility: stimulus variables and environmental variables. Stimulus variables are those factors involving the mark itself. This ARP establishes a set of guidelines for key stimulus variables that contribute to legibility and which should be taken into consideration in the course of specifying and using wire marking equipment. Environmental variables affect the reading of the marking, for example lighting, observer-stimulus distance, orientation of observer to stimulus, clutter, visual acuity of observer, state of mind, and visual exposure duration.
