MIL-DTL-39030F
4.6.18 Endurance (see 3.21). Dummy loads shall be subjected to the specified peak power (when
applicable) and average power for test purposes, for 10 cycles of 1 hour power on and a minimum of 1
hour off, at any frequency within the specified frequency range (see 3.1). The VSWR shall be measured
as specified in 4.6.10 preceding the test and at intervals of 1 hour thereafter during the off period. For
pressurized loads, the internal pressure shall be as specified (see 3.1). For liquid cooled loads the
minimum flow rate and coolant pressure specified (see 3.1) shall be used with the input temperature as
specified.
4.6.19 Overload (see 3.22). The specified overload power shall be applied for the time specified (see
3.1). The load shall then be checked for breakdown and deterioration. VSWR shall then be measured as
specified in 4.6.10.
internal air pressure for at least 5 minutes while immersed in tap water of approximately 20°C. For liquid
cooled loads, coolant chamber shall be subjected to an internal air pressure as specified (see 3.1) for at
least 5 minutes while immersed in tap water of approximately 20°C.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the
contract or order (see 6.2). When actual packaging of materiel is to be performed by DoD or in-house
contractor personnel, these personnel need to contact the responsible packaging activity to ascertain
packaging requirements. Packaging requirements are maintained by the Inventory Control Point's
packaging activity within the Military Service or Defense Agency, or within the military service's system
commands. Packaging data retrieval is available from the managing Military Department's or Defense
Agency's automated packaging files, CD-ROM products, or by contacting the responsible packaging
activity.

6.3 Qualification. With respect to products requiring qualification, awards will be made only for products
which are, at the time of award of contract, qualified for inclusion in Qualified Products List QPL No.
39030 whether or not such products have actually been so listed by that date. The attention of the
contractors is called to these requirements, and manufacturers are urged to arrange to have the products
that they propose to offer to the Federal Government tested for qualification in order that they may be
eligible to be awarded contracts or orders for the products covered by this specification. Information
