General Requirements3.1 Alternate ComponentsWhen this specification or the referenced drawings specify us

22、e 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 if none is required, prior to commencing production, thecontractor shall

23、 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 by thisspecification. The purchaser, at his option, may require a physi

24、cal sample of any “or equal” component.Approval of the submittedlisting and supporting data authorizes the commencement of fabrication of the first article or of production, as applicable, but doesnot relieve the contractor of the responsibility that the “or equal” components perform in accordance w

25、ith specified requirementswhen 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 materials or processes must be approved by the purchaser. It is encouraged that rec

29、ept 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 cleaned in accordance with the drawings.3.6 WeldingWelded joints shall be suc

30、h 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 from scale, paint, grease, and other foreign materials. Welds shall have thorou

31、gh 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, and excess flux. Any acid used in cleaning shall be completely neutralized and

32、removed. Welders shall be certified 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 of no

33、film. Any coating damaged during assembly or examination shall be touched up. There shall be no areas of rust. Finish shall befree of blistering, peeling and chips.3.7.1 Adhesion of PaintThe shelter shall be capable of withstanding, without degradation to the finish, the tests as specifiedin 7.37.Af

34、ter top coat application, 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.3.7.3 ThicknessThickness

35、 of the paint film shall be checked as specified in 7.39.3.8 Finish and ColorSurfaces shall be of the color, treatment, and finish as shown on the drawings. Top coat painting shallbe performed on the fully assembled shelter so as to prevent mismatch of color shading, unless other control techniques

36、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) minimum temperature indoor facility for a minimum of 36 h to ensure adequate coating(s) cure. During thisstorage period the shelter doors and vents s

46、m skins, FRP barrierstrips, 6061-T6 panel extrusions). Prior to use, all critical panel component materials must be qualified in accordance withSpecifications E865, E866, E990, E1091, and E1826. There shall be no skin splices in the panels except where noted on thedrawings. Unless otherwise specifie

47、d (see 13.2), prior to award of contract, the contractor shall submit to the purchaser a certifiedcopy of a laboratory test report and a copy of their process specification covering fabrication of the metallic-faced, nonmetallichoneycomb core sandwich panels they propose to use in the construction o

48、f the end item.
