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 inspector, a complete re-examination
35、 and retest of the unit may be required. Nonconforming units, which have not been corrected, will be con- sidered for acceptance only upon formal application by the contractor to the procuring activity via the cognizant Government representative. 4.7.2 Quality conformance test equipment. Items of te
36、st equipment listed . in table I are required to perform quality conforniance tests specified herein, All items of test equipment shall be of sufficient accuracy and precision to permit valid performance of required tests, Test instruments shall be Cali- brated at regular intervals.
