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.
4.1.1 Responsibility for compliance. All items shall 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
follows:
a. First article inspection (see 4.4)
b. Quality conformance inspection (see 4.5)
