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 Gov
45、ernment 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 rquirements, however, this does not authorize submission of known defective material, either indicated or actual, n
46、or does it commit the Government to accept defective material. 4.2 Inspection svstem.
