ASTM-F2174:2008 Edition

1.1 This practice is used for routinely checking the sensitivity of acoustic emission (AE) sensors. It is intended to provide a reliable, precisely specified way of comparing a set of sensors or telling whether an individual sensor’s sensitivity has degraded during its service life, or both.

1.2 The procedure in this practice is not a calibration and does not give frequency-response information.

1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.4 This practice does not purport to recommend one sensor manufacturer over another nor does it imply that one type of sensor will react differently from another when using this procedure.

1.5 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.
