本文件涵盖了铜或铜合金镀锡、镀银或镀镍导体的绝缘单导体电线的要求，如适用的生成性能表中所规定的（见 附录A 对于样品）。它提供了航空航天应用中使用的绝缘电线系统的各种特性的一般性能要求、额定值和信息。数值测试要求或参数最初是使用英语或公制单位开发的。原始、主要单位首先显示，次要（转换的）单位放在括号中。列出二级单位仅供参考，不视为要求。 导线将根据本标准中规定的许多要求被分配一个性能级别。除了数值测试结果外，这些性能水平应列在适用的性能表中。本标准包含一些测试和参考AS4373测试方法，这些测试和方法尚未被严格确认为重现性。此类方法在各个AS4373检测方法中的精密度和偏倚声明中进行了识别。许多需求具有多个级别的性能。具有基本性能水平的导线可用于一般用途；然而，可能存在需要具有更高性能水平的电线的特殊应用。

This document covers the requirements for insulated, single-conductor, electric wires with tin-coated, silver-coated, or nickel-coated conductors of copper or copper alloy as specified in an applicable generated performance sheet (see Appendix A for sample). It provides general performance requirements, ratings, and information for various characteristics of insulated wire systems used in aerospace applications. Numerical test requirements, or parameters, were originally developed using either English or metric units. The original, primary, units are shown first with the secondary (converted) units in parentheses. Secondary units are listed for information only and are not to be considered requirements. Wire will be assigned a level of performance for many requirements set forth in this standard. These performance levels, in addition to numerical test results, shall be listed in the applicable performance sheet. This standard contains some tests and referenced AS4373 Test Methods that have not been rigorously confirmed as reproducible. Such methods are identified under the Precision and Bias Statements in the individual AS4373 Test Methods. Many requirements have multiple levels of performance. The wire with base level of performance is acceptable for general use; however, there may be special applications that will require wire with higher performance levels.
