1.1 This practice is recommended 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 is degrading during its service life, or both.

1.2 This procedure is not a "calibration" nor does it give frequency response information. It is simply a way of verifying consistency of sensor peak amptitude response.

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

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.
