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