16、 a sample shall be subjected to first article inspection (see 6.3) in accordance with 4.3. 3.2 Materials. Materials and hardware requirements shall be in accordance with this document and with subsidiary documents cited on the applicable drawings. It is encouraged that recycled material be used when

17、 practical as long as it meets the requirements of this specification. 3 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-S-43292D 3.3 Construction and assembly. The end item shall conform to the requirements of this document and to the designs, d

18、etails, and dimensions shown or specified on the applicable drawings, 33.1 Stitching, Stitching shall conform to FED-STD-751. Stitch types shall be as specified on the applicable drawing. Thread breaks, bobbin runouts, or two or more consecutive skipped stitches shall be overstitched not less than 1

19、/2 inch each end, except for type 308 stitching, which shall be overstitched two or three stitches, Runoffs shall be restitched to conform to the required stitch pattern, Backstitching is not required when ends of type 301 stitching are turned under in a hem or held down by other stitching, Thread t

20、ension shall be maintained so that there will be no loose stitching resulting in a loose bobbin or top thread or excessively tight stitching resulting in puckering of the materials sewed, The lock will be imbedded in the materials sewed. All thread ends shall be trimmed, 3.3.1.1 Automatic stitching,

21、 Automatic stitching machines may be used to perform any of the required stitch patterns provided the requirements for stitch pattern, stitches per inch, and size and type of thread are met, and at least three or more tying, overlapping, or backstitches are used to secure the ends of the stitching,

22、3.4 Workmanship. The end item shall conform to the quality of product established by this specification. 4 QUALITY ASSURANCE PROVISIONS 4,l Responsibility for inspection. Unless otherwise specified in the contract or purchase order, the contractor is responsible for the performance of all inspection

23、 requirements (examinations and tests) as specified herein. Except as otherwise specified in the contract or purchase 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

24、Government reserves the right to perform any of the inspections set forth in this specification where such inspections are deemed necessary 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

25、 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 requirements in the specification shall not relieve the contractor of the responsibility of ensuring that all products or supplies sub

26、mitted 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 msterial, either indicate

27、d or actual, nor does it commit the Government to accept defective material. 4 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-S-Ll3272D I6 7777906 0375736 5 MIL-S-43292D 4.1.2 Responsibility for dimensional requirements. Unless otherwise specifi

28、ed in the contract or purchase order, the contractor is responsible for ensuring that all specified dimensions have been met. When dimensions 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

29、all dimensional requirements. 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. When a first article is required (see 3.1 and 6.3

30、), it shall be examined for the defects specified in 44.2 and 4.4.3. 4.4 Quality conformance inspection. Unless otherwise specified, sampling for inspection shall be performed in accordance with MIL-STD-105. 4.4.1 Component and material inspection. In accordance with 4.1, components and materials sh

31、all be inspected in accordance with all the requirements of referenced documents unless otherwise excluded, amended, modified, or qualified in this specification or applicable purchase document. 4.4.2 End item visual examination. The end items shall be examined for the defects listed in table I. The

32、 lot size shall be expressed in units of static lines or connector web assemblies, as applicable. The sample unit shall be one static line or one connector web assembly, as applicable.
