General Requirements3.1 Alternate ComponentsWhen this specification or the referenced drawings specify use of a specific component “or equal,”the
19、 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, if none is required, prior to commencing production, thecontractor shall submit for the purchasers approval, a l
20、ist 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 by thisspecification. The purchaser, at his/her option, may require a physical sample of any “or equal” compon
21、ent. 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 of the responsibility that the “or equal” components perform in accordance with specifiedrequirements when inc
22、orporated 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 materials or processes must be approved by the purchaser. It is encouraged that recycledmaterial be used when practic

25、l 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 shall be properly seatedand tight against the bearing surfaces.All the rivets, except those used in panel bonding,
26、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 cleaned in accordance with the drawings.3.6 WeldingWelded joints shall be such that grinding of the finished w
27、eld 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 from scale, paint, grease, and other foreign materials. Welds shall have thorough penetration, good fusion, and
28、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, and excess flux. Any acid used in cleaning shall be completely neutralized andremoved. Welders shall be certif
29、ied in accordance with SAE-AMS-STD-1595. AWS D17.1/D17.1M. Welding equipment andprocedures shall conform to SAE-AMS-STD-2219.AWS D17.1/D17.1M.3.7 FinishCoatings shall level out to an adherent, continuous, and uniform film without runs, wrinkles, streaks, or areas ofno film. Any coating damaged durin
30、g assembly or examination shall be touched up. There shall be no areas of rust. Finish shallbe free from blistering, peeling, and chipping.3.7.1 Adhesion of PaintThe shelter shall be capable of withstanding, without degradation to the finish, the tests as specifiedin 11.37.NOTE 1After top coat appli
31、cation, the shelter in the deployed mode shall be stored for a minimum of 168 h at a minimum of 70F (21C)70 F (21 C)prior to performing this test.3.7.2 ColorThe color of the paint film shall be compared with an appropriate color chip for the paint specified.6 Available from Standardization Documents

35、. Top coat painting shallbe performed on the fully assembled shelter so as to prevent mismatch of color shading, unless other control techniques areapproved by the purchaser.After top-coat application, the shelter in the deployed mode (that is, expanded) shall be stored in a 70F(21C)70 F (21 C) mini
36、mum temperature indoor facility for a minimum of 36 h to ensure adequate coating(s) cure. During thisstorage period, the shelter doors and vents shall be opened to permit air circulation within the shelter.3.9 ManualsUnless otherwise specified (see 13.2), technical manuals shall be provided with eac
37、h shelter. Stowage provisionfor the manuals shall be located as shown on the applicable drawings.3.10 Terminology related to this specification is defined in Terminology E1749.4. Design and Construction Requirements4.1 Design and ConstructionDesign and construction of the expandable shelter shall co
38、nform to the requirements specifiedon the drawings, all subsidiary drawings and parts lists, and hereinafter. The shelter shall be free of panel delaminations and shallmeet all physical and environmental requirements specified herein.4.2 Container ModeThe shelter in the closed or transport mode shal
39、l be referred to as a container, hereinafter, for the purposeof definition. The shelter, in the container mode, shall be an article of transport equipment meeting ISO freight containerrequirements related to cargo containers. The shelter shall not show structural damage when tested as specified in 1
40、1.20, 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.

Each panel shall be fabricated as a net panel with aluminum extrusions bonded aboutthe p
42、anel perimeter during panel bonding. The inner and outer skins on all joints shall be sealed to provide a water barrier againstthe entrance of moisture to the core material and to the interior of the shelter. The water barrier is to be maintained intact at allpanel cross-sectional openings. All join
43、ts and edges shall be assembled and sealed in a manner to prevent collection and retentionof moisture. Particular emphasis shall be placed on the sealing of all mitered corners. All of the above sealing procedures shall beaccomplished in accordance with Practice E1773. Rivet shafts shall be coated w
