4.3.4 Lifting and tiedown test. To determine conformance to 3.9.10, lifting and tiedown provisions, markings, and the connecting structural members of the vehicle shall be inspected for conformance with MIL-STD-209. All lifting and tiedown provisions and the connecting structural members shall meet the criteria of MIL-STD-209. Test results that show the

provisions do not meet the criteria of MIL-STD-209 shall constitute failure of this test.

4.3.5 Rail impact test. The vehicle shall be tested in accordance with 4.3.4 prior to the rail impact test. To determine conformance to 3.9.8, the vehicle shall be inspected for agreement with the dimensions of the AAR and GIC diagrams referenced in 3.9.8 and shall be subjected to the rail impact test of MIL-STD-810. The vehicle shall be inspected for spillage of lubricants, fuel, or water and structural damage after each impact. Electrical shorts and normal operations and performance shall be checked and tested following completion of the test. Performance degradation or permanent deformation of any part is considered a deficiency and a failure. Spillage of lubricants, fuel or water; structural damage; or electrical shorts shall also constitute failure of this test.

4.4 Failure. Failure of the first production vehicle to meet requirements of the contract shall be cause for the Government to refuse acceptance of all vehicles under contract until corrective action has been taken.

4.5 Inspection of production vehicles. The contractor's inspection system shall as a minimum assure that the vehicle is complete and conforms to the physical, dimensional and rating requirements specified herein and found in the manufacturer's non-government products. The inspection system shall assure the vehicle is capable of meeting the performance requirements specified herein and found in the manufacturer's non-government products for similar use (see 6.1).
