4.4 First production vehicle inspection. The first vehicle produced under the contract,
prior to prime painting, shall be inspected by the contractor at his plant under the direction of and
in the presence of Government representatives. The purpose of the inspection shall be to
determine vehicle conformance to the contract. Acceptance of the first production vehicle shall
not constitute a waiver by the Government of its rights under the provisions of the contract.
4.4.1 Weight. The first production vehicle shall be weighed to determine the curb
weight and distribution of the curb weight on front and rear axles. The total imposed loads on
front and rear axles shall be computed by the contractor and verified by the Government, using
the curb weight, the operator weight at 175 pounds, and the payload to provide the specified
GVW or a payload of 2,500 pounds, whichever requires the greater GVW. The calculated
imposed loads on the front and rear axles shall be compared to the suspension, axle and tire load
capacity ratings to determine if these components are of adequate capacity to meet contractual
requirements.
*
4.4.2 Road test. The vehicle, for 4x2 and 6x4 models and for models built to all wheel
drive while on the chassis manufacturer's production line shall be road tested by the contractor
with payload. The road test shall be for not less than 10 miles at speeds up to 52 mph. The
vehicle, for all wheel drive models qualifying under 3.1.1.13, shall be road tested with and
without payload. Payload shall be distributed first, so that the front axle is loaded to GAWR and
the vehicle is loaded to GVW and second, with the rear axle loaded to GAWR and the vehicle
loaded to GVW. The road test for each of the three conditions shall be for not less than 30 miles
at speeds up to 52 mph over highways and gravel roads and for not less than 5 miles at speeds up
to 15 mph over cross country terrain with ground and grade requiring all wheel drive. During the
loaded and empty portions of the road test, the brakes shall be applied firmly, bringing the
vehicle to a sudden stop not less than 5 times during each portion of the road test. During the
road test, the front and rear suspension and the drivetrain shall be periodically inspected for
interference and contact with other vehicle components. Abnormal contact of the drivetrain or
suspension components with other components shall be cause for rejection. Front spring
bumpers shall not make contact with frame stops except under the most extreme cross country
conditions. Operational or mechanical failures of the vehicle components during the road test
shall be cause for rejection. Failure includes permanent deformation as well as breakage.
*
4.4.2.1 Alternate fuel test. When operational capability on JP-4, JP-5 and JP-8 is
specified, the first production vehicle shall be tested with these fuels. The contractor shall obtain
a sufficient amount of JP-4, JP-5 and JP-8 to allow the first production vehicle to perform the
following tests. When changing fuel types, the fuel tank and filters shall be drained, the new fuel
substituted, and sufficient idling or driving shall be performed to purge the previous fuel type
