46、ved facility as designated by the contracting officer for evaluation in accordance with the provisions of 4.2.2 and 4.2.3. The first article sample shall consist of five (5) sets of parts and five (5) complete test set assemblies which have been produced by the contractor or furnished by a supplier
47、and which have been manufactured using the same production processes, pro- cedures and equipment which will be used in fulfilling the contract. All parts and materials including packaging and packing shall be obtained from the same source of supply as will be used in regular production. Prior to sub
