When thread breaks or bobbin run-outs occur during stitching, the stitching shall be repaired by restarting the stitching a minimum
24、 of 1/2 inch back of the end of the stitching. b. Thread breaks or two or more consecutive skipped or runoff stitches noted during inspection of the item (in-process or end item) shall be repaired by overstitching. The stitching shall start a minimum of 1/2 inch in back of the defective area, contin
25、ue over the defective area, and continue a minimum of 1/2 inch beyond the defective area onto the existing stitching. Loose or excessively tight stitching shall be repaired by removing the defective stitching without damaging the materials and restitching in the required manner. O (When making the a
26、bove repairs in a. and b. above, the ends of the stitching are not required to be backstitched.) 3.4.2.4 Thread ends. All thread ends that are visible on the finished item shall be trimmed to a maximum length of 1/4 inch. 3.4.3 Fusing of ends of nylon webbing. The ends of the nylon webbing shall be
27、fused smooth in such a manner as to prevent sharp edges from forming. apparatus used to fuse the webbing ends shall be capable of providing sufficient heat to fuse the cut ends of the webbing yarns together. The 3.4.4 Setting of snap fasteners. A hole shall be prepunched or predrilled through the ma
28、terials to receive the button and eyelet components of the snap fasteners. The hole shall be smaller than the outside diameter of the button and eyelet barrels so that the barrel must be forced through the hole. The hole shall not be punched in the setting operation with the button or eyelet barrel.
29、 The fasteners shall be securely clinched without cutting the surrounding materials and no more than three splits shall occur in the button or eyelet barrels. * 1 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-B-4382bC 4 7777706 0376305 O I MIL

The end item shall conform to the
34、 quality of product established by this specification. 4. QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspection. Unless otherwise specified in the contract or purchase order, the contractor is responsible for the performance of all inspection requirements (examinations and tests) as specifi
35、ed 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 Government reserves the right to perform any of t
36、he 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 5. The inspection set forth in this specificatio

The absence of any inspection requirements in the specification shall not relieve the contractor of the responsibility of ensuring that all products or supplies submitted to the Government for acceptance comply wi
38、th 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, either indicated or actual, nor does it commit the Government
39、to accept defective material. 5 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-B-4382bC 84 i 7777706 0396306 2 I MIL -B -4382 6C 4.1.2 Responsibility for dimensional requirements.
