QUALITY ASSURANCE PROVISIONS 4.1 Responsibility f

37、or Inspection Unless otherwise specified in the contract or purchase order, the supplier is responsible for the performance of all inspection requirements as specified herein. Except as otherwise specified in the contract or purchase order, the supplier may use his own or any other facilities suitab

38、le for the performance of the inspection requirements specified herein, unless disapproved by the qualifying activity. The qualifying activity reserves the right to perform any of the inspections set forth in the specification where such inspections are deemed necessary to assure supplies and servic

39、es conform to prescribed requirements. 4.1.1 Responsibility for Compliance All items must meet the requirements of Sections 3 and 5. The inspection set forth in this specification shall become a part of the contractors overall inspection system or quality program. The absence of any inspection requi

40、rements in the specification shall not relieve the contractor of the responsiility of assuring that all products or supplies submitted to the qualifying activity for acceptance comply with the requirements of the contract. Sampling in quality conformance does not authorize submission of known defect

41、ive material, either indicated or actual, nor does it commit the qualifying activity to acceptance of defective material. SAE INTERNATIONAL AS81914 5 OF 174.1.2 Test Equipment and Inspection Facilities Test and measuring equipment and inspection facilities of sufficient accuracy, quality and quantit

42、y to permit performance of the required inspection shall be established and maintained by the contractor.
