19、s3. General Requirements3.1 Alternate 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

20、manufacture of the first article, or if 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

21、 compatible with the end item covered by thisspecification. The purchaser, at his option, may require a physical 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, b

22、ut doesnot relieve the contractor of the responsibility that the “or equal” components perform in accordance with 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.

23、Any change to the proposed materials or processes must be approved by the purchaser. It is encouraged that recycledmaterial be used when practical as long as it meets the requirements of this specification.3.3 WorkmanshipThe shelter, including all parts and accessories, shall be constructed and fini

24、shed in a workmanlike mannerwith particular attention given to removal of burrs and sharp edges, accuracy of dimensions, thoroughness of soldering, welding,painting, alignment of parts of assemblies, and the tightness of screws, bolts, and so forth. Gaskets shall not be torn or split andshall be fre

25、e of finish. Cloth components shall 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 un

26、damaged, and the rivet heads shall 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 Cleanin

27、gAfter fabrication, parts shall be 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

28、 welded shall be cleaned andfree from 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 remo

29、ve any scale, oxidation products, 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

30、, continuous and uniform film without runs, wrinkles, streaks, or areas of nofilm. 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 with

31、standing, without degradation to the finish, the tests as specifiedin 7.37.

32、opriate color chip for the paint specified.3.7.3 ThicknessThickness 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

33、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) minimum temperature indoor facility for a minimum of 36 h to ensure adequate coating(s) cure.

34、 During this storage periodthe 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 each shelter. Stowage provisionfor the manuals shall be located as shown on the applicable dr
