4.2 Qualification inspection. Qualification inspection shall be in accordance with MIL-PRF-19500 and as specified
herein.
4.2.1 JANHC and JANKC qualification. JANHC and JANKC qualification inspection shall be in accordance with
MIL-PRF-19500.
4.2.2 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 require 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.
4.3 Screening (JANS, JANTXV, and JANTX levels only). Screening shall be in accordance with table E-IV of
MIL-PRF-19500, and as specified herein. Specified electrical measurements shall be made in accordance with table
