1.1本试验方法描述了带辅助负载处理附件的空中人员装置（APD）的声发射（AE）测试程序。 1.1.1涵盖的设备本试验方法涵盖以下类型的车载高空作业人员装置，带有补充负载处理附件: 1.1.1.1可扩展动臂APD， 1.1.1.2铰接动臂APD，以及 1.1.1.3 1.1.1和1.1.1.2的任何组合。 1.1.2未涵盖的设备本试验方法不涵盖以下任何设备: 1.1.2.1无辅助负载处理附件的绝缘高空作业人员装置， 带平台的挖掘机井架， 1.1.2.3带平台的起重机，以及 1.1.2.4具有负载提升能力的架空设备，位于平台附近以外的任何位置。 注1-本试验方法并非用于验证架空设备结构完整性的独立无损检测方法。应使用其他无损检测方法来补充结果。 1.2声发射测试方法用于检测和区域定位发射源。发射源的验证可能需要使用其他无损检测（NDT）方法，如射线照相、超声波、磁粉、液体渗透和目视检查。 ( 警告 -本试验方法要求对试验车辆的上部结构施加外部荷载。试验期间，必须小心保护人员和设备，防止车辆或部件发生意外故障或不稳定。） 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 本试验方法提供了一种评估受控负载下APD内局部源快速释放能量产生的声发射的方法。在故意施加受控的预定负载期间，产生的能量释放发生。这些能量释放可由合格人员监测和解释。 本试验方法允许在受控载荷下对高空作业装置的主要部件进行试验。该测试方法利用客观标准进行评估，并可随时停止，以调查特定关注区域或防止故障继续到最终故障。 本试验方法提供了一种检测声发射的方法，这些声发射可能是缺陷或不规则，或两者兼有，影响天线装置的结构完整性或预期用途。 使用本试验方法发现的声发射源应通过更精细的声发射试验方法或其他无损技术（视觉、液体渗透、射线照相、超声波、磁粉等）进行评估。可能需要其他无损检测来定位APD中存在的缺陷。 通过本试验方法在架空设备中发现的缺陷区域应进行维修，并酌情重新测试。 维修程序建议不在本试验方法的范围内。

1.1 This test method describes a procedure for acoustic emission (AE) testing of aerial personnel devices (APDs) with supplemental load handling attachments. 1.1.1 Equipment Covered—This test method covers the following types of vehicle-mounted aerial personnel devices with supplemental load handling attachments: 1.1.1.1 Extensible-boom APDs, 1.1.1.2 Articulating-boom APDs, and 1.1.1.3 Any combination of 1.1.1.1 and 1.1.1.2. 1.1.2 Equipment Not Covered—This test method does not cover any of the following equipment: 1.1.2.1 Insulated aerial personnel devices without supplemental load handling attachments, Digger-derricks with platform, 1.1.2.3 Cranes with platform, and 1.1.2.4 Aerial devices with load-lifting capabilities located anywhere other than adjacent to the platform. Note 1—This test method is not intended to be a stand-alone NDT method for the verification of the structural integrity of an aerial device. Other NDT methods should be used to supplement the results. 1.2 The AE test method is used to detect and area-locate emission sources. Verification of emission sources may require the use of other nondestructive test (NDT) methods, such as radiography, ultrasonics, magnetic particle, liquid penetrant, and visual inspection. ( Warning —This test method requires that external loads be applied to the superstructure of the vehicle under test. During the test, caution must be taken to safeguard personnel and equipment against unexpected failure or instability of the vehicle or components.) 1.3 This standard does not purport to address all of the safety problems, 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. ====== Significance And Use ====== 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. 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. 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. 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. 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.
