The absence of any inspection requirements in the specification shall not relieve the contractor of the responsibility of ensuring that all products or s

24、upplies 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, ei

25、ther indicated or actual, nor does it commit the Government to accept defective material. 4,1,2 Responsibility for dimensional requirements. Unless otherwise specified in the contract or purchase order, the contractor is responsible for ensuring .that.all specified dimensions have been met, When dim

26、ensions cannot be examined on the end item, inspection shall be made at any point, or at all points in the manufacturing process necessary to ensure compliance with all dimensional requirements. a 4.2 Classification of inspections.
