MIL-T-83808
4.6.7.3, 4.6.7.10, and Air Transportability Certification. Upon completion of the random sample testing,
the contractor shall prepare a test report in accordance with MIL-STD-831. An authorized Government
representative shall countersign all data sheets of the report.
4.5.2.1
dom sample test failure. When a vehicle fails to successfully complete any random
sample test, the cause of the failure shall be determined, corrective action shall be taken, and the test
shall be repeated to verify adequacy of the corrective action. Tests not involving the defective
component(s) may be continued pending the investigation of the failure. Vehicles to be delivered pursuant
to the contract shall be inspected for all defects identified during all random sample tests and may not be
accepted prior to verification of adequacy for the corrective action for a random sample test failure.
4.5.3
Each production vehicle shall be given a road test of at least
Road test (production vehicle).
five miles over paved surfaces. The following shall be observed for evidence of improper operation:
Service and parking brakes.
a.
Transmission operable in all gears.
b.
Engine starting and operation at all speeds.
d. Engine RPM.
e. Top speed.
f . Tire wear.
g. Fluid leaks.
h. Unusual noises, vibrations or unsafe conditions
i . Drawbar pull test.
NOTE: This test shall be performed before individual tests a and b (see 4.5)
4.6.1
The vehicle shall be inspected to determine compliance with the re-
surface finishes, protective coatings and their application, welding and riveting, and markings. Any
painted surface on the exterior of the vehicle may be tested in accordance with paragraph 4.6.1.1 of this
specification. Check the vehicle for proper coolant level, oil level, fuel level, and hydraulic levels. For the
first article and random sample vehicles, this examination shall be accomplished by use of a checklist
which lists each requirement not validated by a test and the results of the examination
4.6.1.1
es ion (wet) tape test . This method covers a procedure suitable for establishing acceptabil-
ity of intercoat and surface adhesion of the polyurethane coating system The test will be accomplished on
each production end item, e.g., loader, trailer, vehicle
a The test is not applicable to a unit where the surface area or contour of the unit is such that
the test would be physically impossible to accomplish, e.g., individual components such as
motors or engines.
b. Adhesion tests shall be made on the completed exterior finish on the painted area after
drying for a period preferably of at least 48 hours The test will be accomplished on only one
area unless failure occurs, then several areas will be checked to determine that a satisfactory
level of adhesion has been achieved. Three consecutive failures are grounds for rejection.
Failures are defined as any visible peeling, chipping or defects
c. Perform the wet tape test as follows:
(1)
Soak a clean cloth in distilled water (size at least 6 inches X 3 inches).
(2) Fold the cloth into a square while it is still wet and place it on the area to be tested
(3) Place a piece of plastic over the wet cloth The plastic must completely cover the
cloth and hold the cloth in contact with the test surface
