Standard Test Method for Acoustic Emission Testing of Insulated and Non-Insulated Aerial Personnel Devices with Supplemental Load Handling Attachments
适用范围：<p>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.</p> <p>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.</p> <p>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.</p> <p>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.</p> <p>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.</p><p id="s00002">1.1 This test method describes a procedure for acoustic emission (AE) testing of aerial personnel devices (APDs) with supplemental load handling attachments.</p> <p id="s00003">1.1.1 <span class="italic"><span class="italic">Equipment Covered</span>8212;</span>This test method covers the following types of vehicle-mounted aerial personnel devices with supplemental load handling attachments:</p> <p id="s00004">126.96.36.199 Extensible-boom APDs,</p></p> <p id="s00005">188.8.131.52 Articulating-boom APDs, and</p></p> <p id="s00006">184.108.40.206 Any combination of 220.127.116.11 and 18.104.22.168.</p></p> <p id="s00007">1.1.2 <span class="italic"><span class="italic">Equipment Not Covered</span>8212;</span>This test method does not cover any of the following equipment:</p> <p id="s00009">22.214.171.124 Aerial personnel devices without supplemental load handling attachments,</p></p> <p id="s00010">126.96.36.199 Digger-derricks with platform,</p></p> <p id="s00011">188.8.131.52 Cranes with platform, and</p></p> <p id="s00012">184.108.40.206 Aerial devices with load-lifting capabilities located anywhere other than adjacent to the platform.</p></p> <p class="desc" id="N00015"> <span class="smallcap">Note</span> 18212;This test method is not intended to be a stand-alone NDT method for the verification of the structural integrity of an aerial device.
