ActiveNon-destructive testing-Acoustic emission inspection-Primary calibration of transducers
无损检测 声发射检测 换能器的一级校准
📋 Scope / 适用范围 ai_extracted
This standard specifies the method for the absolute calibration of acoustic emission transducers. Its purpose is to establish a unified standard for acoustic emission testing, to lay the foundation for data correlation, and to provide interpretation for test results obtained at different times and locations. Describing the performance of acoustic emission transducers requires specifying an acceptable method. This standard establishes a primary calibration method for acoustic emission transducers coupled to the surface of a solid medium to receive elastic waves. The calibration determines the transducer's response to the acoustic wave frequencies commonly received in acoustic emission testing. The voltage response of the transducer is determined at discrete frequency intervals from approximately 10 kHz to 1 MHz. The input is a known dynamic displacement on the coupling surface. The calibration unit is output voltage per mechanical input (displacement, velocity, acceleration). This standard is applicable to the calibration of secondary standard transducers and transducers used for testing.
本标准规定了声发射换能器绝对校准的方法。其目的是为声发射检测建立统一的标准，为实现数 据相关建立基础，并且对不同（在不同时间不同地点所获得）的检测结果提供解释。 描述声发射换能器的性能必须规定一种可接受的方法。 本标准为藕合在固体介质表面接受弹性波的声发射换能器建立一套一级校准方法。校准是换能器 对在声发射检测中经常接收的声波频率的响应。换能器的电压响应在大约10 kH：至I MH：的分立频 率间隔中来确定。输人是在藕合表面上已知的动态位移。校准单位是输出电压每机械输人（位移、速 度、加速度）。本标准适用于二级标准换能器和用于检测的换能器的校准。
