本国际标准规定了声发射传感器的二次校准方法 固体介质表面的弹性波接收器。国际标准适用于实验室 三级标准传感器和声发射应用传感器。 二次校准会产生传感器对通常在工作中遇到的波的频率响应 声发射功，即瑞利波。产生用于校准的信号的源是 安装在与被测传感器（SUT）相同的试块表面上。传感器的灵敏度为 在100 kHz到1 MHz的范围内确定激励。灵敏度值通常在 频率相隔约10千赫。校准单位为每单位机械输入的伏特 （位移、速度或加速度）。

This International Standard specifies a method for the secondary calibration of acoustic emission sensors as receivers of elastic waves at the surface of a solid medium. The International Standard is applicable to laboratory tertiary standard sensors and acoustic emission applications sensors. The secondary calibration yields the frequency response of a sensor to waves of a type normally encountered in acoustic emission work, namely Rayleigh waves. The source producing the signal used for the calibration is mounted on the same surface of a test block as the sensor under test (SUT). The sensitivity of the sensor is determined for excitation within the range of 100 kHz to 1 MHz. Sensitivity values are usually determined at frequencies approximately 10 kHz apart. The units of the calibration are volts per unit of mechanical input (displacement, velocity or acceleration).
