4.2 Government verification. Quality assurance operations performed by the contractor will be subject to Government verification at unscheduled intervals. Verification will consist of observation of the operations to determine that practices, methods and procedures of the contractor's inspection are being properly applied. Failure of the contractor to promptly correct product deficiencies discovered shall be cause for suspension of acceptance until correction has been made or until conformance of product to specification criteria has been demonstrated.

4.3 First production vehicle inspection. The first vehicle of each class 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 conformance to the contract. Acceptance on 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 curb weight and distribution of the curb weight on the front and rear axles. The total imposed loading on the 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 required to provide the specified GVW. 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.

4.3.3 Compaction unit. Compaction cycle time shall be measured to determine conformance to 3.5.4.2. When specified (see 6.2), the first production vehicle compaction unit shall be tested using refuse to assure complete functional operation of the cycle for delivering refuse from the hopper into the body, compacting the refuse and discharging the refuse.

4.3.4 Road test. The vehicle shall be driven for a distance of not less than ten miles over class I (concrete, asphalt, or brick) roads at maximum allowable traffic speed limits, but not less than 50 mph. The load shall be discharged and the vehicle returned to the contractor's plant.

4.3.5 Examination. When testing in completed, the vehicle shall be cleaned completely. The vehicle shall be examined for evidence of distortion, malfunction and damage. The contractor shall be responsible for correcting defects disclosed during the operation and for taking corrective action to prevent recurrence of such defects in subsequently furnished vehicle.
