The reinspection of a nonconforming unit may be limited to the test or examination which defined the nonconformance, or when so directed by the cognizant inspecto
10、r, a complete re-examination and retest of the unit may be required. Nonconforming units, which have not been corrected, will be considered for acceptance only upon formal application, by the contractor to the Bureau of Naval Weapons via the cognizant Government representative. 4. 5.2 Acceptance tes
