LOT ACCEPTANCE TEST / QCI (sampling basis)

To provide greater reliability assurance with respect to environmental, mechanical assembly and endurance of the devices.
Within the ESA/SCC (now ESCC) system the Lot Acceptance Tests (now Lot Validation tests) are specified in Chart V (now Chart F3) of the appropriate Generic Specification and indicate which tests are performed, how many parts are required for each test and how many failures are permitted for each of the tests.
Within MIL system, QCI/TCI are specified in the generic specification.
• QCI group A and B correspond to electrical test and LAT3 tests
• QCI group C corresponds to Endurance subgroup (LAT2 and part of LAT1)
• QCI group D corresponds to Mechanical subgroup (LAT1)
• QCI group E corresponds to radiation tests
