    18、es subjected to this test shall not be delivered on the contract or order. 3.3.9 Outgassing (space level codes A and T). Outgassing shall be performed as specified in MIL-PRF-55342. 3.4 Marking. Marking is not required on the resistor; however, each unit package shall be marked with the PIN assigned

    19、 herein (see 1.2), vendor CAGE code, and date and lot codes. 3.5 Manufacturers eligibility (military applications). The approved sources of supply listed on this drawing shall be qualified to at least one product on the Qualified Products List for MIL-PRF-55342. They shall have successfully passed t

    20、he power moisture resistance test as witnessed and certified by an official company representative with 30 samples (10 low, 10 critical, 10 high) with zero defects.
