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 their 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 ensure that the 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 of 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 accept defective
material.
4.2 Classification of inspections. The inspection requirements specified herein are
classified as quality conformance inspections (see 4.3).
