4.5 Conformance inspection of equipment before packaging. Each unit of each lot of equipment shall be subjected
to bounce preconditioning (see 3.9) prior to inspection. The contractor shall perform the inspection specified in 4.4
and 4.5.1 through 4.5.3.2. This does not relieve the contractor of his responsibility for performing any additional
inspection which is necessary to control the quality of the product and to assure compliance with all specification
requirements. Failure to meet any requirement as a result of bounce precondition shall be classified as a defect and
recorded as such. The Government will review and evaluate the contractor's inspection procedure and examine the
contractor's inspection records. In addition, the Government, at its discretion, may perform all or any part of the
specified inspection to verify the contractor's compliance with specified requirements (see 6.7). Test equipment for
Government verification inspection shall be made available by the contractor. Each unit which will be subjected to
group A, group B, group C, or first article inspection shall be preconditioned after final assembly (see 4.6).
