B2.1.3. For 230-kV and above rated units, the corona ring shall not exhibit positive
streamers during the 60-Hz tests. In addition, any corona discharges during high
voltage tests must not impinge on the insulating portion of the boom.
B2.2. Inspection and Nondestructive Tests. Following is an outline of the inspection
and nondestructive tests procedure to be performed after the insulated aerial lift
equipment is completely assembled, mounted, all other tests completed, and
immediately prior to delivery of equipment:
B2.2.1. The inspections and tests shall be performed by a recognized and reputable
nondestructive testing organization specified or agreed by the contracting officer.
B2.2.2. Acoustic emission tests (ASTM F 914 for Acoustic Emission for Insulated
Aerial Personnel Devices and ASTM F (number not assigned as of this writing) for
Acoustic Emission for Insulated Material Handling Aerial Devices) shall be
performed on the insulated aerial lift device, with transducers placed from the end of
the boom in at least eight locations down to the bottom of the main frame assembly.
Test loading for insulated material handling aerial lift devices should be limited to
one and one-half times rated Ioad.
B2.2.3. High stress areas of the fiberglass boom sections shall be radiographically
(x-ray) tested to detect internal cracks or deficiencies not revealed through visual
B2.2.4. Welded areas in steel booms subject to high stress and critical steel castings
in booms, turrets, and outriggers shall be radiographically tested to cracks, slag, and
inadequate penetration of welds.
B2.2.5 Critical boom pins and bolts shall be tested by radiographic and/or ultrasonic
methods to detect any deficiencies.
B2.2.6. Deficiencies detected in critical components by inspection and
nondestructive testing shall be corrected by the manufacturer and the previous
deficient component(s) retested by the inspection and testing organization.
B2.3.Reports. The contractor shall provide the contracting officer with formal
inspection and results for all acceptance testing.
B2.4 Witness of Tests. The contractor shall advise the contracting officer at least 3
working days prior to all acceptance testing so that a representative may witness all
or part of the tests.
