18、ComponentsWhen this specification or the referenced drawings specify use of a specific component “or equal,”the contractor may substitute a component equal to the specified component provided that the contractor complies with thefollowing requirements. 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. Any change to the proposed materi

22、als or processes must be approved by the purchaser.

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.
