1.1本规程提供了一种统一的方法，用于规定电接触和连接系统的性能要求（或报告测试结果）。导体和连接器系统性能可通过本规程单独或组合规定。 1.2本规程可用于使用金属导体和触点的可分离或永久触点。 1.3本规程提供了信号和功率应用的方法。 1.4本规程未规定确定接触性能所需的样品制备或测试顺序。本规程的用户有责任确定适用于应用的应用测试顺序。 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/材料的适当材料安全数据表（MSDS）中确定的危险，建立适当的安全和健康实践，并在使用前确定监管限制的适用性。 ====意义和用途====== 5.1本规程基于电阻作为触点性能指标的使用。 5.2现有标准，如第节中引用的标准 2. 作为代表性示例，提供应用测试条件的基础。可能必须对现有标准的程序或样本量或两者进行修改，以提供电阻测量，并满足用户可能指定的可变性指数要求。 5.3本规程适用于使用多种试验方法，以确保在给定应用中具有令人满意的性能。

1.1 This practice provides a uniform method of specifying performance requirements for (or reporting test results of) electrical contact and connection systems. Both conductor and connector system performance may be specified by this practice, separately or in combination. 1.2 This practice may be used for separable or permanent contacts employing metallic conductors and contacts. 1.3 This practice provides methods for both signal and power applications. 1.4 This practice does not specify the sample preparation or test sequences required for determining contact performance. It is the responsibility of the user of this practice to determine the applied test sequence(s) appropriate for the application. 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 Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== 5.1 This practice is based on the use of electrical resistance as an indicator of contact performance. 5.2 Existing standards, such as those referenced in Section 2 as representative examples, provide the basis for applied test conditions. Modifications in procedure or sample size, or both, of existing standards may have to be made to provide for resistance measurement and to meet variability index requirements that a user may specify. 5.3 This practice accommodates the use of multiple test methods, as may be required to assure satisfactory performance in a given application.
