4. VERIFICATION

4.1 Classification of inspections. The inspection requirements specified herein are classified as follows:

Qualification inspection (see 4.2).

Screening (see 4.3).

Conformance inspection (see 4.4 and tables I and II).

4.2 Qualification inspection. Qualification inspection shall be in accordance with MIL�PRF�19500 and as specified

herein.

4.2.1 Group E qualification. Group E inspection shall be performed for qualification or re-qualification only. In

case qualification was awarded to a prior revision of the specification sheet that did not request the performance of

table II tests, the tests specified in table II herein that were not performed in the prior revision shall be performed on

the first inspection lot of this revision to maintain qualification.
