Contract Quality Assurance Inspection (Origin). Contract quality assurance inspection shall be applied at the contractor’s facility prior to being offered for acceptance under the contract. Each machine and all peripheral equipment added to the machines shall be fully assembled and perform all functions in accordance with this specification. Quality conformance inspection shall consist of the examination in 4.6 and the tests in 4.7. The machines shall pass the examination, all tests, and contract quality assurance inspection to be acceptable for shipment.

Final Inspection/Acceptance Test (Destination). Final Inspection and acceptance test shall be performed on each machine to ensure conformance with this purchase description.

The acceptance test shall be performed only after each machine is installed at its final location. The acceptance test shall consist of the examination in 4.6 and all tests in 4.7.

Each machine shall pass the examination and all tests to be accepted.

Examination. The equipment shall be examined for design, dimensions, construction, materials, components, electrical equipment and workmanship to determine compliance with the requirements of this specification in accordance with ARP4048.

Tests. Unless otherwise specified within this document, all programs, instruments, materials, material handling equipment, qualified personnel, and tools required to perform and evaluate the tests shall be furnished by the contractor.
