practicable, provided the control assembly produced meets all other requirements
of this specification. Used, rebuilt or remanufactured components, pieces and
parts shall not be incorporated in the control assembly.

QUALITY ASSURANCE PROVISIONS
4.1 Responsibility for inspection. Unless otherwise specified in the contract
or purchase order, the contractor is responsible for the performance of all
inspection requirements as specified herein. Except as otherwise specified in
the contract or purchase order, the contractor may use his own or any other
facilities suitable for the performance of the inspection requirements speci-
fied herein, unless disapproved by the Government. The Government reserves the
right to perform any of the inspections set forth in the specification where such
inspections are deemed necessary to assure supplies and services conform to
4.1.1 Component and material inspection. The contractor is responsible for
insuring that components and materials used are manufactured, examined, and
tested in accordance with referenced specifications and standards as applicable.
4.1.2 Responsibility for compliance. All items must meet all requirements of
sections 3 and 5. The inspections set forth in this specification shall become a
part of the contractor's overall inspection system or quality program. The
absence of any inspections requirements in the specification shall not relieve
the contractor of the responsibility of assuring that all products or supplies
submitted to the Government for acceptance comply with all requirements of the
contract. Sampling in quality conformance does not authorize submission of known
defective material, either indicated or actual, nor does it commit the Government
to acceptance of defective material.
