Prior to manufacture of the first article or, i

19、f none is required, prior to commencing production, thecontractor shall submit for the purchasers approval, a list identifying each proposed “or equal” component together with proof thateach listed component is functionally equal to the specified component and is compatible with the end item covered

20、 by thisspecification. The purchaser, at his/her option, may require a physical sample of any “or equal” component. Approval of thesubmitted listing and supporting data authorizes the commencement of fabrication of the first article or of production, as applicable,but does not relieve the contractor

21、 of the responsibility that the “or equal” components perform in accordance with specifiedrequirements when incorporated into the end item.3.2 Materials and ComponentsMaterials and components shall conform to the documents listed in Section 2 and as specifiedherein.

24、all be clean and free of holes, cuts, or tears.All latches utilized for erection and closingof the shelter shall be properly adjusted before the shelter is prepared for delivery to the purchaser.3.4 RivetingRiveting joints shall be tight. The joined parts shall be undamaged, and the rivet heads shal

25、l be properly seatedand tight against the bearing surfaces.All the rivets, except those used in panel bonding, shall be dipped in polysulfide sealant justprior to insertion; however, a dab of polysulfide sealant shall be applied to the head of each rivet.3.5 CleaningAfter fabrication, parts shall be

26、 cleaned in accordance with the drawings.3.6 WeldingWelded joints shall be such that grinding of the finished weld shall not be a requirement, except when specifiedon the drawing. Spot, stitch, and seam welds shall be as indicated on the drawings. All surfaces to be welded shall be cleaned andfree f

27、rom scale, paint, grease, and other foreign materials. Welds shall have thorough penetration, good fusion, and shall be freefrom scabs, blisters, abnormal pock marks, cracks, voids, slag inclusions, and other harmful defects. Welded assemblies shall becleaned to remove any scale, oxidation products,

28、 and excess flux. Any acid used in cleaning shall be completely neutralized andremoved. Welders shall be certified in accordance with SAE-AMS-STD-1595. Welding equipment and procedures shall conformto SAE-AMS-STD-2219.3.7 FinishCoatings shall level out to an adherent, continuous, and uniform film wi

29、thout runs, wrinkles, streaks, or areas ofno film. Any coating damaged during assembly or examination shall be touched up. There shall be no areas of rust.

Design and Construction Requirements4.1 Design and ConstructionDesign and construction of the expandable shelter shall conform to the requirements specifiedon the drawings, all subsidiary drawings and parts lists, and hereinafter. The shelter shall be f

36、ree of panel delaminations and shallmeet all physical and environmental requirements specified herein.4.2 Container ModeThe shelter in the closed or transport mode shall be referred to as a container, hereinafter, for the purposeof definition. The shelter, in the container mode, shall be an article

37、of transport equipment meeting ISO freight containerrequirements related to cargo containers. The shelter shall not show structural damage when tested as specified in 11.20, 11.22,11.23, and 11.28-11.35, and shall not show leakage when tested as specified in 11.24 and 11.24.1-11.24.3.
