MIL-DTL-82068D
4.3 Conformance inspection. Conformance inspection shall include the examination of
4.3.1 Sampling. Sampling shall be conducted in accordance with ASQ Z1.4, inspection
level II. The acceptance quality limit (AQL) shall be as stated in the contract or other
procurement document (see 6.2).
4.4 Examination. Each sample pesticide sprayer shall be examined for compliance with
the requirements specified in section 3 of this specification. Any redesign or modification of the
contractor's standard product to comply with specified requirements, or any necessary redesign or
modification following failure to meet specified requirements shall receive particular attention
for adequacy and suitability. This element of inspection shall encompass all visual examinations
and dimensional measurements. Noncompliance with any specified requirements or presence of
one or more defects preventing or lessening maximum efficiency shall constitute cause for
rejection.
4.5 Tests. The first article shall be subjected to the tests described in 4.5.1 through 4.5.8.
Each production sample unit shall be subjected to the testing described in 4.5.8. Failure to pass
any test shall constitute cause for rejection.
4.5.1 Trailer test. The sprayer, with between 50- and 75-percent capacity load of water,
shall be attached to a suitable towing vehicle, and towed for not less than 1 hour, 1/2 hour of
which shall be over improved roads at an average speed of 40 mph, and the remaining 1/2 hour
shall be over dry, unimproved roads at an average speed of 20 mph, to determine conformance to
the performance requirements specified in 3.6.2. Signs of damage or malfunction, developed
during or after the trailer tests and the sprayer performance tests (see 4.5.3), shall be cause for
rejection. Instability due to shift of the liquid load shall be cause for rejection.
4.5.2 Testing solution. An emulsion prepared by mixing one gallon of 60 percent Naled
(dibrom) emulsifiable concentrate with 99 gallons of water shall be used as a typical pesticide for
test purposes.
4.5.3 Sprayer or spray gun test. No less than 100 gallons of pesticide, composed as
specified in 4.5.2, shall be placed in the tank. The engine, pump, and agitator shall be set in
operation and shall be operated for a total of not less than 100 hours without overheating the
pesticide. During the test operation, not less than the following procedures shall be performed:
a. Insert the maximum capacity flow-control disk in the hose nozzle, and discharge into
the tank filler opening in solid stream adjustment until all air is exhausted from the hose.
b. Set the pressure-control valve so that the pressure gage indicates at least 90 percent of
the operating pressure (see 3.6.1), and discharge not less than three spray patterns, in adjustments
between solid stream and fine mist, into the tank opening to determine consistency of spray
pattern and control.
c. Using the maximum capacity flow-control disk at the operating pressure, measure the
discharge from the spray gun in solid stream pattern, to determine a flow rate in conformance to
