The tests in this initial qualification table are applicable when performed only for the
8、dust covers. When testing the connector plug and connector receptacle, the dust cover shall be included as part of the initial qualification of these components and not tested separately. In either case, the dust cover shall meet the requirements for the same inspections as listed in table II. Provi

When testing the connector plug and connector receptacle as part of the initial qualification, one end of each dust cover lanyard shall be affixed to the connector. 2/ Seal material. Tests in this column may be exclude
17、d if other components that use the same seal material are qualified to this defense specification. 3/ Seal integrity. These tests verify the sealing integrity, verify aspects unique to the dust cover configuration, and so shall be performed as part of a dust cover qualification for a change in seal
18、material or dust cover design. 4/ Plating. Tests in this column other than those for group 1 visual and mechanical inspection may be excluded if other components that use the same plating are qualified to this defense specification with one provision: The other components must contain the same knurl
19、 or other style gripping surface as dust covers being qualified. 5/ Shell size. With the exception of those tests listed in group 1, tests in this column can be excluded for smaller shell sizes once dust covers for larger shell sizes are qualified to this defense specification. 6/ Lanyard attachment
20、. Lanyard attachment shall consist of a coated stainless steel wire rope with ring. This column applies when a material or configuration (such as attachment method to dust cover) is changed. 7/ Group 1 mated pair are to be used for Groups 2 and 3 tests. Group 4 may be performed before Group 1, and,
21、except for electromagnetic effects, with separate samples. 8/ Salt spray. Two options: a. Use same two mated pair from the fluid immersion test. b. Use separate mated pair. 9/ Electromagnetic effects. Two (2) mated pair from the fluid immersion, salt spray, or Group 2/3 samples after that Groups tes
22、t completion may be used. 10/ Parts only, assembly not required. 11/ Specific test practices for physical, mechanical, environmental and material tests, including clarifications and further details, are found in MIL-STD-1678-3. 12/ Shock test. Mated dust covers shall be affixed to standard shock fix
23、ture 4A for bulkhead mounting in the same manner as the dust covers are affixed to the connector. There shall be no damage or loosening of parts and mated dust covers shall not become a missile hazard. 13/ For receptacle dust cover only. Two of the six mated pair from Group 1 shall be used. Test sam
24、ple configuration shall consist of a receptacle dust cover mated to a connector receptacle.

When test is performed
25、with a dust cover mated to a connector and the dust cover is removed for the post test water penetration inspection, orient the connector so that it is facing away from the center of the earth. This orientation will prevent water that may have penetrated threads prior to seals from entering the conn
26、ector (resulting in a false positive for water penetration). Maintenance aging: Not applicable. Twist: Not applicable. Mating durability: Not applicable. Dust cover mating durability: Dust covers shall be mated then de-mated for 500 cycles to the applicable connector plug or connector receptacle. Du
27、st cover seals shall not be rendered unfit for sealing (as determined by no wear, no displacement, and no penetration after the succeeding water pressure test). Threads shall not exhibit signs of wear. Plating shall remain intact to extent that dust cover can be mated and de-mated after performance
28、of sand and dust and after salt spray. Water pressure: Applicable except immerse in fresh water to equivalent depth of 3 feet (0.9 m) for a period of 30 minutes. Next, the dust covers shall be removed, externally cleaned and dried, and visually examined for water penetration into each dust cover. No
29、 water penetration past the sealed surfaces of the dust cover interior shall occur. Gasket: Gasket shall be bonded to cover or mechanically retained. Lanyard: Lanyard shall be free to rotate on fastener affixed to dust cover. A fastener shall be affixed to other end of lanyard for dust covers to be
30、used with wall mounting receptacles. A ring shall be affixed to other end of lanyard for dust covers to be used with jamnut mounting receptacles. Lanyard attachment shall consist of a coated stainless steel wire rope with ring. Provided by IHSNot for ResaleNo reproduction or networking permitted wit
