4 QUALITY ASSURANCE PROVISIONS
4.1 Responsibility for inspection. Unless otherwise specified in the contract, the contractor
is responsible for the performance of all inspection requirements as specified herein. Except as
otherwise specified in the contract, the contractor may use his own or any 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 prescribed requirements.
* 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 for ensuring that all products or
supplies submitted to the Government for acceptance comply with all requirements of the
contract. Sampling inspection, as part of manufacturing operations, is an acceptable practice to
ascertain conformance to requirements, however, this does not authorize submission of known
defective material, either indicated or actual, nor does it commit the Government to acceptance
of defective material.
4.2 Government verification. Quality assurance operations performed by the contractor will
be subject to Government verification at unscheduled intervals. Verification will consist of
observation of the operations to determine that practices, methods, and procedures of the
contractor's inspection are being properly applied. Failure of the contractor to promptly correct
product deficiencies discovered shall be cause for suspension of acceptance until correction has
been made or until conformance of product to specification criteria has been demonstrated.
