The tests in this
10、initial qualification table are applicable when performed only for the 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
11、 the requirements for the same inspections as listed in table II. Table II.

Unless otherwise specified, the connector plug dust cover shall be mated to the connector receptacl
18、e dust cover for each of the tests/inspections. 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 excluded if other components that use the
19、 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 material or dust cover design. 4/
20、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 or other style gripping surface a
21、s dust covers being qualified. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-PRF-64266/10A 5 Table II. Qualification inspections Continued. 5/ Shell size. With the exception of those tests listed in group 1, tests in this column can be excluded
22、 for smaller shell sizes once dust covers for larger shell sizes are qualified to this defense specification. 6/ Lanyard attachment. 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 du
23、st 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, 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 pa
24、ir. 9/ Electromagnetic effects. Two (2) mated pair from the fluid immersion, salt spray, or Group 2/3 samples after that Groups test completion may be used. 10/ Parts only, assembly not required. 11/ Specific test practices for physical, mechanical, environmental and material tests, including clarif
25、ications and further details, are found in MIL-STD-1678-3. 12/ Shock test. Mated dust covers shall be affixed to standard shock fixture 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 sh
26、all not become a missile hazard. 13/ For receptacle dust cover only. Two of the six mated pair from Group 1 shall be used. Test sample configuration shall consist of a receptacle dust cover mated to a connector receptacle. 14/ Water pressure. When test is performed with a dust cover mated to a conne
27、ctor 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 connector (resulting in a false positi
28、ve 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. Dust cover seals shall not be render
29、ed 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 of sand and dust and after salt sp
30、ray. 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 water penetration past the sealed
31、 surfaces of the dust cover interior shall occur. Gasket: Gasket shall be bonded to cover or mechanically retained. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-PRF-64266/10A 6 Lanyard: Lanyard shall be free to rotate on fastener affixed to du
32、st cover. A fastener shall be affixed to other end of lanyard for dust covers to be used with split backshells. A cable loop shall be affixed to other end of lanyard for dust covers to be used with solid backshells and other configurations without screw retention availability. Lanyard attachment sha
33、ll consist of a coated stainless steel wire rope with fastener or with cable loop. The inside diameter of the cable loop at a right angle to the crimp sleeve shall meet the values specified for dimension C (see figure 1).
