Unless otherwise specified in the contract or purchase order, the contractor is responsible for the performance of all inspection requirements as specified herein. Except as otherwise speci- fied in the contract or purcha
41、se 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 the specification where such inspectio
42、ns are deemed necessary to assure supplies and services conform to prescribed requirements. 4.1.1 Responsibility for compliance. All items must meet all requirements of sections 3 and 5. The inspection set forth in this specification shall become a part of the contractors overall inspection system o
43、r quality program. The absence of any inspection requirements in the specification shall not relieve the contractor of the responsibility of assuring that all products or supplies sub- mitted to the Government for acceptance comply with all requirements of the con- tract. Sampling in quality conform
44、ance does not authorize submission of known defective material, either indicated or actual, nor does it commit the Government to acceptance of defective material. 4.1.2 Certification of quality conformance. When specified in the contract or order, certification data for level 1 material shall be pre
45、pared (see 6.2.2 and appendix C). 4.2 Classification of inspections. The inspection requirements specified herein are classified as follows: (a) First article inspection (see 4.3). (b) Quality conformance inspection (see 4.4). 4.3 First article inspection. First article inspection shall be conducted
46、 in accordance with section 43 of the ABS Rules which requires data in support of mechanical properties, weldability, and compliance with the rules when new or 7 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-special steel or production methods are
47、proposed or when new steel mills begin production. Approval by ABS to produce a particular grade of ABS steel also approves the facility to produce the same grade of steel to this specification. 4.3.1 First article inspection report. When specified in the contract or order, a first article inspectio
48、n procedure and report shall be prepared (see 6.2.2). 4.3.2 First article inspection of Z grades. First artjcle inspectio? shall be performed on each type and thickness range of Z and TZ grades of steel to approve any contractor who has not previously supplied these grades to this speci- fication. F
49、irst article inspection shall include all tests specified in section 43 of the ABS Rules and the additional tests specified in 4.3.2.1 through 4.3.2.3. Thickness ranges shall be up to 1 inch (25 mm), over 1 inch (25 mm) to 2 inches (51 mm), over 2 inches (51 mm) to 4 inches (102 mm), and over 4 inches (102 mm) to 6 inches (152 mm).
