or other foreign matter.
4. 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
(examinations and tests) 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 specified herein, unless disapproved by the
Government. The Government reserves the right to perform any of the inspections set forth in this
specification where such inspections are deemed necessary to ensure supplies and services conform
to prescribed requirements (see 6.2).
4.1.1 Responsibility for compliance. All items shall meet all requirements of sections 3 and

defective material,either indicated or actual, nor does it commit the Government to acceptance
of defective material.
