1.1 本指南包含指定和评估带有实心或绞合导线的压接型终端的电接触性能的实践。 1.2 本指南提供了与压接导线终端的电气接触性能相关的信息。本节不涵盖压接端子选择和使用的其他方面。 1.3 本指南中讨论的方法仅适用于导线终端，即导体和端子之间的电气接触界面。不包括对端子评估重要的其他方面，如电绝缘的特性和性能、应变消除特性的有效性以及端子与其他电路元件之间的接触质量。 1.4 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任熟悉所有危险，包括制造商提供的本产品/材料的适当安全数据表（SDS）中确定的危险，建立适当的安全、健康和环境实践，并在使用前确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 本指南的目的是为最终产品制造商和其他用户提供为成功应用压接导线端子而推荐的技术信息和方法。 4.2 对于任何给定用途，通常可以选择可用的端子类型，采用不同的机械设计、材料和安装工具。尽管可供选择的端子可能具有类似的额定值，通常根据导线尺寸和组合而定，但其在最终产品中的电接触性能可能会有很大差异。对于许多应用，终端的选择和完成终端的质量在很大程度上影响最终产品的可靠性和用户安全。 本指导文件包含关于压接导线端子的选择、组装和质量控制的专门信息，涵盖了在预期应用中实现可靠长期运行所必需的方面。这些信息通常不会出现在商业文献或教科书中。所讨论的方法将连接电阻用作终端质量的主要测量值，并将连接电阻随时间的变化用作终端劣化的测量值。这些方法以现代电接触理论和实践为基础。

1.1 This guide contains practices for specifying and evaluating the electrical contact performance of crimped-type terminations with solid or stranded conductors. 1.2 This guide provides information relevant to the electrical contact performance of a crimped wire termination. It does not cover other aspects of selection and use of crimped terminals. 1.3 The methods discussed in this guide apply only to the wire termination, which is the electrical contact interface between the conductor(s) and the terminal. Other aspects important to terminal evaluation, such as the properties and performance of electrical insulation, the effectiveness of strain relief features, and the quality of contact between the terminal and other electrical circuit elements, are not included. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 The purpose of this guide is to provide end-product manufacturers and other users with technical information and methods recommended towards the achievement of successful application of crimped wire terminals. 4.2 For any given use, there is generally a choice of terminal types available, employing different mechanical design, materials, and installation tooling. Although terminals available to choose from may be similarly rated, typically according to wire sizes and combinations, their electrical contact performance in the end product may vary substantially. For many applications, the end-product reliability and user safety is substantially influenced by the choice of terminal and the quality of the completed termination. This guidance document contains specialized information on selection, assembly, and quality control of crimped wire terminals, covering aspects considered to be necessary to achieve reliable long-term operation in the intended application. This information is not generally found in commercial literature or textbooks. The methods discussed utilize connection resistance as the primary measure of termination quality, and change of connection resistance with time as the measure of termination deterioration. The methods are based on a foundation of modern electrical contact theory and practice.
