Qualifications shall be in accordance
10、 with MIL-DTL-38999 with the following exceptions: Group I: Durability: Wired connectors shall meet the durability requirements of MIL-DTL-38999, with the following exceptions: The total number of cycles of mating and unmating shall be 500, in the following sequences: 200 cycles of normal mating and
11、 unmating, 50 cycles of normal mating with pull-separation unmating, 200 cycles of normal mating and unmating, 50 cycles of normal mating with pull-separation unmating. The lanyard release velocity during the pull-separation force unmating cycles shall be 9.15 meters per second. Separation force: Up
12、on conclusion of the group I test, all samples shall be subjected to an axial force applied by a mated plug assembly. The connector shall meet the requirements of separation force when the applied load is 1,800 200 Newton. External bending moment: Wired connectors shall meet external bending moment
13、requirements of MIL-DTL-38999 with the following exception: Size 25 loading shall be 28.3 Newton-meters. Group II: Durability: Wired connectors shall meet the durability requirements of MIL-DTL-38999, with the following exceptions: The total number of cycles of mating and unmating shall be 500, in t
14、he following sequences: 200 cycles of normal mating and unmating, 50 cycles of normal mating with pull-separation unmating, 200 cycles of normal mating and unmating, 50 cycles of normal mating with pull-separation unmating.
