34、red using the same materials, equipment, processes and procedures as used in regular production. All parts and materials, excluding packaging and packing must be the same as used for regular production and shall be obtained from the same source of supply. The Government reserves the right to require
35、 new first article samples until such time as an acceptable sample is submitted. 4.4.1 Examination, tests and facility.
