1.1系统性能验证方法模拟安装传感器的检查物品。产生的应力波在检查物品中传播，并由传感器以类似于声发射的方式检测。 1.2本指南描述了可用于验证声发射系统响应的方法，包括传感器、耦合剂、传感器安装装置、电缆和系统电子部件。 1.3可使用本文件评估的声发射系统性能特征包括一些波形参数和源位置精度。 1.4性能验证通常在开始检查之前进行。 1.5如果怀疑系统性能可能发生变化，可在检查期间进行性能验证。 1.6性能验证可在检查完成后进行。

1.1 System performance verification methods stimulate the examination article on which the sensor is mounted. The resulting stress wave travels in the examination article and is detected by the sensor(s) in a manner similar to acoustic emission. 1.2 This guide describes methods which can be used to verify the response of an Acoustic Emission system including sensors, couplant, sensor mounting devices, cables and system electronic components. 1.3 Acoustic emission system performance characteristics, which may be evaluated using this document, include some waveform parameters, and source location accuracy. 1.4 Performance verification is usually conducted prior to beginning the examination. 1.5 Performance verification can be conducted during the examination if there is any suspicion that the system performance may have changed. 1.6 Performance verification may be conducted after the examination has been completed.
