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
