Standard Test Method for Acoustic Emission Testing of Insulated and Non-Insulated Aerial Personnel Devices with Supplemental Load Handling Attachments

Abstract

5.1 This test method provides a means of evaluating acoustic emissions generated by the rapid release of energy from localized sources within an APD under controlled loading. The resultant energy releases occur during intentional application of a controlled predetermined load. These energy releases can be monitored and interpreted by qualified individuals. 5.2 This test method permits testing of the major components of an aerial device under controlled loading. This test method utilizes objective criteria for evaluation and may be discontinued at any time to investigate a particular area of concern or prevent a fault from continuing to ultimate failure. 5.3 This test method provides a means of detecting acoustic emissions that may be defects or irregularities, or both, affecting the structural integrity or intended use of the aerial device. 5.4 Sources of acoustic emission found with this test method shall be evaluated by either more refined acoustic emission test methods or other nondestructive techniques (visual, liquid penetrant, radiography, ultrasonics, magnetic particle, etc.). Other nondestructive tests may be required to locate defects present in APDs. 5.5 Defective areas found in aerial devices by this test method should be repaired and retested as appropriate. Repair procedure recommendations are outside the scope of this test method.
