1.1This test method describes a procedure for acoustic emission (AE) testing of aerial personnel devices (APDs) with supplemental load handling attachments.
1.1.1Equipment Covered—This test method covers the following types of vehicle-mounted aerial personnel devices with supplemental load handling attachments:
1.1.1.1Extensible-boom APDs,
1.1.1.2Articulating-boom APDs, and
1.1.1.3Any combination of 1.1.1.1 and 1.1.1.2.
1.1.2Equipment Not Covered—This test method does not cover any of the following equipment:
1.1.2.1Aerial personnel devices without supplemental load handling attachments,
1.1.2.2Digger-derricks with platform,
1.1.2.3Cranes with platform, and
1.1.2.4Aerial 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.
1.2The 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.)
1.3The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
1.4This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
