1.1本指南描述了可用于评估通过钎焊或焊接制造的电触点组件的粘接质量的超声波检测程序。 1.2以英寸-磅为单位的数值应视为标准值。括号中给出的值仅供参考。 1.3 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====== 建议在编制钎焊或焊接电接触粘合区域无损评估规范时使用本指南。 6. 建议的程序旨在提高不同实验室之间测试数据的再现性。设备型号和技术人员技能之间确实存在具体差异，这将限制绝对相关性。本指南说明了行业参与者中观察到的实际变化程度。 仅凭超声波检测不能确保了解粘结完整性。其他属性（即强度）可能需要与破坏性试验方法相关。

1.1 This guide describes ultrasonic testing procedures that can be used for evaluating the bond quality of electrical contact assemblies manufactured by brazing or welding. 1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 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 ====== This guide is recommended to be used in preparing specifications for the non-destructive evaluation of brazed or welded electrical contact bonded area. 6 The recommended procedures are meant to improve the reproducibility of test data among various laboratories. Specific differences among equipment models and technician skills do exist which will limit absolute correlation. This guide provides an indication of the degree of variability which has been observed as realistic among industry participants. Ultrasonic testing alone does not insure an understanding of bonded integrity. Other attributes (that is, strength) may require correlation with destructive test methods.
