ACCEPTANCE TESTING AND IN-SERVICE
INSPECTION AND
TESTING OF INSULATED AERIAL LIFT EQUIPMENT
(VEHICLE MOUNTED)
B1. General. Periodic electrical and mechanical testing programs are essential in
order to evaluate the integrity and stability of the insulating and support components
of vehicle mounted insulated aerial lift equipment over its expected working life.
Therefore, vehicle mounted insulated aerial lift equipment test programs shall be as
follows:

B2. Acceptance Tests. Electrical acceptance testing for vehicle mounted insulated
aerial lift equipment is well defined in ANSI A92.2-1979. All new units are subjected
to these acceptance tests and certified before they are placed in service.
Procurement specifications for new vehicle mounted insulated aerial lift equipment
should require the Manufacturer's Certification Test described herein. Additionally,
procurement specifications should also require inspection and nondestructive testing
by an independent testing organization.

B2.1.Electrical Acceptance Test. Following is an outline of the acceptance test
procedure to be performed by the unit manufacturer:
procedure to be performed by the unit manufacturer:
B2.1.1. The assembled insulated aerial lift equipment in operable condition shall be
tested on a grounded vehicle or a grounded test stand. The voltage shall be applied
to the upper electrode of the insulated boom, and the lower end of the insulated
boom shall be connected to ground potential. The test voltage shall be applied at a
Iow voltage and steadily raised until the test voltage is reached and maintained for
the recommended test period.

B2.1.2. Tests shall consist of rated, double rated, and at the option of the
manufacturer, either momentary withstand or switching surge voltage (see the

three minutes, recording the dielectric arm current at the start and end of the three
minute test period, during which the dielectric arm current shall not increase more
than ten percent or exceed the values in
