MIL-S-62294B(AT)

4.3 First production vehicle inspection. The first 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. Weld specimens (see 3.22.4) shall be used by Government

representatives as a guide in determining the quality of all applicable welds. All welds on the

first production vehicle and on all subsequent production vehicles shall be compared with

applicable workmanship specimens prior to priming or painting the vehicle. 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 Semitrailer weight. The semitrailer shall be weighed to determine curb weight and

distribution of curb weight on the kingpin and the rear axles. The imposed loading on the

kingpin and rear axles, with payload, shall be computed using curb weight and the semitrailer

payload distributed as specified in 3.4 thru 3.4.2. The rated capacity of the axles, suspension

system and tires shall be compared to the loads imposed to determined if they conform to

contract requirements.

* 4.3.2 Road test. The semitrailer, loaded with rated payload, shall be coupled to a

truck-tractor. The tractor-semitrailer combination shall be driven a distance of not less than

100 miles under the conditions specified under 3.3. At least 20 percent of the distance shall be

over hard uneven terrain. At least five sudden stops shall be made from a speed not less than

20 mph. Tracking ability shall be observed to verify conformance to 3.3.3.

* 4.3.2.1 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:
