4.3 First production vehicle inspection. The first production vehicle produced under the
contract shall be inspected by the contractor at his plant under the direction, and in the presence,
of Government representatives. The purpose of the inspection shall be to determine vehicle
conformity with the requirements of 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.
4.3.1 Vehicle weight. The first production vehicle shall be weighed to determine net weight
and distribution of net weight on kingpin and rear axles. The imposed loading on kingpin and
rear axles will be computed using the net weight with the rated payload (see 3.2.3) in the tank.
The calculated imposed load on rear axles will be utilized to ascertain that the suspension, axles
and tires are of adequate capacity to meet contract requirements.
4.3.2 Road test. The road test shall consist of coupling the semitrailer, loaded with water, to
a truck tractor. The tractor-trailer combination shall be driven a distance of not less than
100 miles under the conditions specified in 3.3. At least 20 percent of the distance shall be over
unimproved roads. At least five sudden stops shall be made from a speed of not less than
20 mph with tank filled to approximately 60 percent capacity, to determine that baffles are of
adequate structural strength. During the road test, the semitrailer shall be observed to determine
conformance to tracking ability requirements specified in 3.3.3.
* 126.96.36.199 Test failure. The vehicle shall successfully complete the entire test. Failure of the
vehicle to successfully complete the test shall be cause for nonacceptance of the contract
quantity, pending correction of deficiencies and evidence of corrective action which shall
prevent the recurrence of similar deficiencies in the contract quantity. Failure of the vehicle to
successfully complete the test shall not constitute an excusable delay in meeting scheduled
deliveries. The equipment shall be closely monitored throughout the test for interference with
towing operations, and for instability as evidenced by poor tracking or uncontrollable
sideslipping, skidding, swerving, or tilting. The equipment also shall be closely monitored for
loosening of parts, interference between parts, leakage of fluids or lubricants, overheating of
components, and for damage, permanent distortion, or excessive wear of parts and components.
The equipment shall be disassembled to the extent necessary for inspection for unusual wear or
damage to components. Substitution of a new semitrailer or replacement of a. major component
may require complete retest at the discretion of the Government representatives. Rejection of the
test semitrailer shall be for damage or deficiencies, including but not limited to the following:
Damage caused by collision
Failure of any major component
Vibration due to misalinement of wheels or frame
Vibration due to the type of construction or mounting
