1.1 This practice uses Acoustic Emission (AE) examination for monitoring of structures, such as pressure vessels or piping systems that can be stressed by hydrostatic means. 1.2 The basic functions of an AE monitoring system are to detect, locate, and classify emission sources. Other methods of nondestructive testing (NDT) may be used to further evaluate the significance of acoustic emission sources. 1.3 This practice can be used to replace visual methods which are unreliable and have significant safety risks. 1.4 This practice describes procedures to install and monitor acoustic emissions resulting from the forces induced by controlled hydrostatic pressure. 1.5 Units- The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
Rationale: This standard practice will benefit the hydraulic fracturing industry, providing a reliable method to certify high pressure piping for continued service.
