other facilities suitable for the performance of the inspection requirements
specified 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 Responsibility for compliance. All items must meet all requirements
of sections 3 and 5. The inspection set forth in this specification shall become
a part of the contractor's overall inspection system or quality program. The
absence of any inspection 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.
