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 Respons ibilitv 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 the 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.
