Scope: This standard specifies a secondary calibration method for acoustic emission sensors that receive surface elastic waves in solid media. This standard applies to the calibration of the laboratory's tertiary standard sensors and sensors used for detection. This standard gives the frequency response of sensors to Rayleigh waves which are common in acoustic emission work. The signal source for calibration and the sensor under test (SUT) are mounted on the same surface of the test block. The sensitivity of the sensor is determined by excitation in the range of 100kHz to 1MHz. The frequency resolution is about 10kHz. Calibration units are volts per mechanical input (displacement, velocity or acceleration).
