Scope
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.
