17、n accordance with ASME B16.15. 4. QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspection. Unless otherwise specified in the contract, the contractor is responsible for the performance of all inspection requirements as specified herein. Except as otherwise specified in the contract, the contr

18、actor 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 nec

19、essary to ensure supplies and services conform to prescribed requirements. 4.1.1 Responsibility for compliance. All items shall meet all requirements of sections 3 and 5. The inspection set forth in this document shall become a part of the contractors overall inspection system or quality program. Th

20、e absence of any inspection requirements in this document 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 manufacturing operations

21、, 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.

Components and materials shall be inspected in accordance with all the requirements specified herein and in applicable referenced documents. 4.2 Classification of inspections. The inspection requirements specified

23、herein are as follows: a. First article inspection (see 4.2.1). b. Quality conformance inspection (see 4.2.2). 4.2.1 First article inspection3.2. The first article inspection shall be performed on one fitting when a first article is required (see and 6.2). This inspection shall include the examinati

24、on of 4.3 and the test of 4.4. The first article may be either a first production item or a standard production item from the suppliers current inventory provided the item meets the requirements of the specification and is representative of the design, construction, and manufacturing technique appli

25、cable to the remaining items to be furnished under the contract. 4.2.2 Quality conformance inspection 4.3.

26、he requirements in section 3 of this document. This element of inspection shall encompass all visual examinations and dimensional measurements. Noncompliance with any specified requirements or presence of one or more defects preventing or lessening maximum efficiency shall constitute cause for rejec

27、tion. 4.4 Test. 4.4.1 Air pressure test. The first article shall be subjected to an air-pressure test of not less than 60 pounds per square inch gage (415 kilopascal) while the fitting is under water. The fitting shall not leak air at any part of the surface. 4.4.2 Alternate pressure test. As an alt

28、ernate test, the fitting shall be subjected to an internal hydrostatic pressure of two times the pressure rating for a period of one minute. Under the hydrostatic pressure test, the fitting shall not leak or sweat at any part of the surface. 4.5 Preparation for delivery inspection. The preservation,

29、 packaging, packing, and marking of the item shall be inspected to verify conformance to the requirements of section 5. 5. PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When packaging of materiel is to be perfo

30、rmed by DoD or in-house contractor personnel, these personnel need to contact the responsible packaging activity to ascertain packaging requirements. Packaging requirements are maintained by the Inventory Control Points packaging activities within the Military Service or Defense Agency, or within th

31、e Military Services system commands. Packaging data retrieval is available from the managing Military Departments or Defense Agencys automated packaging files, CD-ROM products, or by contacting the responsible packaging activity. 6.
