1.1本实施规程建议用于测试和测量声发射电子元件或装置的工作特性。（见附录 X1 有关组件和单元的说明。）本规程不用于声发射仪器的常规检查，而是用于定期校准或发生故障时。当传感器存在时，除了建议标准化系统增益（使它们在通道间均衡）的方法外，本文件中未讨论传感器。 1.2如果制造商在操作和维护手册中提供了测试和测量细节，则制造商的方法应与本实践中描述的方法结合使用。 1.3困难或有疑问的仪器测量应咨询电子工程人员。 1.4本实施规程中规定的方法不具有排他性或详尽性。 1.5应记录用于测试和测量声发射仪器组件或单元的方法（技术），以及此类测试和测量的结果。文件应包括照片、图表、计算和表格（如适用）。 1.6常用的AE系统使用小型或微型计算机控制数据的收集、存储、显示和分析。 基于计算机的系统的特点包括与声发射事件相关的广泛测量参数选择。然而，这种选择通常是在获得数据后进行的。这意味着单独记录声发射信号以供以后分析，或者在每个超过选定阈值的声发射信号上测量所有可用参数。后者通常是这样。制造商为每个系统提供了规范，规定了系统的工作范围和条件。计算机的所有校准和验收测试- 基于AE的系统必须使用制造商的规范作为指导。本规程不包括计算机或计算机外围设备的测试。 1.7本标准无意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在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 This practice is recommended for use in testing and measuring operating characteristics of acoustic emission electronic components or units. (See Appendix X1 for a description of components and units.) It is not intended that this practice be used for routine checks of acoustic emission instrumentation, but rather for periodic calibration or in the event of a malfunction. The sensor is not addressed in this document other than suggesting methods for standardizing system gains (equalizing them channel to channel) when sensors are present. 1.2 Where the manufacturer provides testing and measuring details in an operating and maintenance manual, the manufacturer's methods should be used in conjunction with the methods described in this practice. 1.3 Difficult or questionable instrumentation measurements should be referred to electronics engineering personnel. 1.4 The methods set forth in this practice are not intended to be either exclusive or exhaustive. 1.5 The methods (techniques) used for testing and measuring the components or units of acoustic emission instrumentation, and the results of such testing and measuring should be documented. Documentation should consist of photographs, charts or graphs, calculations, and tabulations where applicable. 1.6 AE systems that use mini or micro computers to control the collection, storage, display, and analysis of data are in common use. Features of the computer-based systems include a wide selection of measurement parameters relating to the AE event. This selection, however, is usually made after the data have been acquired. This implies that the AE signals are individually recorded for later analysis, or that all the available parameters are measured on every AE signal that exceeds the selected threshold. The latter is usually the case. The manufacturer provides a specification for each system that specifies the operating range and conditions for the system. All calibration and acceptance testing of computer-based AE systems must use the manufacturer's specification as a guide. This practice does not cover testing of the computer or computer peripherals. 1.7 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
