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 w
18、ith 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 list identifying each proposed “or equal” component together with proof thateach listed component is functionall
19、y equal to the specified component and is 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 a
20、rticle or of production, as applicable, but 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 lis
21、ted in the Referenced Documentssection and as specified herein. Any change to the proposed materials or processes must be approved by the purchaser. It isencouraged that recycled material be used when practical as long as it meets the requirements of this specification.3.3 WorkmanshipThe shelter, in
22、cluding all parts and accessories, shall be constructed and finished 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 and assemblies, and the tightness of screws, bolts,
23、 and so forth. Gaskets shall not be torn or split andshall be free 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 Rive
24、tingRiveting joints shall be tight. The joined parts shall be undamaged, and the rivet heads shall be properly seatedand tight against the bearing surfaces.
