significance And Use:

scope:

1.1 This test method describes a procedure for non-destructive testing using acoustic emission (AE) testing for aerial personnel devices, which do not have a supplemental load handling attachment.

1.1.1 Equipment Covered-This test method covers the following types of vehicle-mounted insulated aerial personnel devices:

1.1.1.1 Extensible boom aerial personnel devices,

1.1.1.2 Articulating boom aerial personnel devices, 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 Material-handling aerial devices,

1.1.2.2 Digger-derricks with platform, and

1.1.2.3 Cranes with platform.

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.

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.

1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.4 This 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 and health practices and determine the applicability of regulatory limitations prior to use.
