* 4.3.3.1 Test course. The total test mileage shall be on roads and highways within the general
geographic limits of the place of manufacture and adjoining states. Any special highway permits
required shall be obtained by the contractor. The course shall be arranged to return the vehicle to
the manufacturer's plant at the completion of each 1600 km (1,000 miles), if applicable, or at the
completion of the test otherwise, for inspection and chassis servicing.
* 4.3.3.2 Test loads. The semitrailer shall be tested for 90 percent of the mileage with the
semitrailer loaded as specified in 3.4 and for 10 percent of the mileage with the semitrailer empty.
Average speeds during all road tests shall be as close as possible to those specified in 3.3.
* 4.3.3.3 Road 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 any 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;
(a)
Damage caused by collision
(b)
Failure of any major component
(c)
Vibration due to misalinement of wheels or frame
(d)
Vibration due to the type of construction or mounting
(e)
Evidence of abnormal tire wear due to misalinement or unbalance
