16、Alternate ComponentsWhen this specification or thereferenced drawings specify use of a specific component “orequal,” the contractor may substitute a component equal to thespecified component provided that the contractor complieswith the following requirements. Prior to manufacture of thefirst articl
17、e, or if none is required, prior to commencingproduction, the contractor shall submit for the purchasersapproval, a list identifying each proposed “or equal” compo-nent together with proof that each listed component is func-tionally equal to the specified component and is compatiblewith the end item
18、 covered by this specification. The purchaser,at his option, may require a physical sample of any “or equal”component. Approval of the submitted listing and supportingdata authorizes the commencement of fabrication of the firstarticle or of production, as applicable, but does not relieve thecontract
19、or of the responsibility that the “or equal” componentsperform in accordance with specified requirements whenincorporated into the end item.3.2 Materials and ComponentsMaterials and componentsshall conform to the documents listed in the ReferencedDocuments section and as specified herein. Any change
20、 to theproposed materials or processes must be approved by thepurchaser. It is encouraged that recycled material be used whenpractical as long as it meets the requirements of this specifi-cation.3.3 WorkmanshipThe shelter, including all parts and ac-cessories, shall be constructed and finished in a
21、workmanlikemanner with particular attention given to removal of burrs andsharp edges, accuracy of dimensions, thoroughness of solder-ing, welding, painting, alignment of parts and assemblies, andthe tightness of screws, bolts, and so forth. Gaskets shall not betorn or split and shall be free of fini
22、sh. Cloth components shallbe clean and free of holes, cuts or tears. All latches utilized forerection and closing of the shelter shall be properly adjustedbefore the shelter is prepared for delivery to the purchaser.3.4 RivetingRiveting joints shall be tight. The joined partsshall be undamaged, and
23、the rivet heads shall be properlyseated and tight against the bearing surfaces. All the rivets,except those used in panel bonding, shall be dipped inpolysulfide sealant just prior to insertion, however, a dab ofpolysulfide sealant shall be applied to the head of each rivet.3.5 CleaningAfter fabricat
24、ion, parts shall be cleaned inaccordance with the drawings.3.6 WeldingWelded joints shall be such that grinding ofthe finished weld shall not be a requirement, except whenspecified on the drawing. Spot, stitch, and seam welds shall beas indicated on the drawings.All surfaces to be welded shall becle
25、aned and free from scale, paint, grease, and other foreignmaterials. Welds shall have thorough penetration, good fusion,and shall be free from scabs, blisters, abnormal pock marks,cracks, voids, slag inclusions, and other harmful defects.Welded assemblies shall be cleaned to remove any scale,oxidati
26、on products, and excess flux. Any acid used in cleaningshall be completely neutralized and removed. Welder shall becertified in accordance with SAE-AMS-STD-1595. Weldingequipment and procedures shall conform to SAE-AMS-STD-2219.3.7 FinishCoatings shall level out to an adherent, con-tinuous and unifo
27、rm film without runs, wrinkles, streaks, orareas of no film. Any coating damaged during assembly orexamination shall be touched up. There shall be no areas ofrust. Finish shall be free of blistering, peeling and chips.3.7.1 Adhesion of PaintThe shelter shall be capable ofwithstanding, without degrad
28、ation to the finish, the tests asspecified in 7.37.3.7.1.1 After top coat application, the shelter in the de-ployed mode shall be stored for a minimum of 168 h at aminimum of 70F (21C) prior to performing this test.3.7.2 ColorThe color of the paint film shall be comparedwith an appropriate color chi
