1.1本方法涵盖了声发射（AE）传感器的绝对校准要求。校准产生了传感器对表面波的频率响应，这种波通常在声发射工作中遇到。传感器电压响应在约10 kHz至1 MHz的离散频率间隔下确定。输入是一个既定的垂直于安装表面的动态位移。校准的单位是每单位机械输入（位移、速度或加速度）的输出电压。 1.2 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 method covers the requirements for the absolute calibration of acoustic emission (AE) sensors. The calibration yields the frequency response of a transducer to waves, at a surface, of the type normally encountered in acoustic emission work. The transducer voltage response is determined at discrete frequency intervals of approximately 10 kHz up to 1 MHz. The input is a given well-established dynamic displacement normal to the mounting surface. The units of the calibration are output voltage per unit mechanical input (displacement, velocity, or acceleration). 1.2 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 establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
