MIL-DTL-22442G

a. Cable assemblies shall be clamped and suspended in the vertical position with the "Y"

junction/crotch securely clamped at the flexure point and will not turn or twist during flexing.

Figure 1 is a typical test setup.

b. A one pound weight shall be attached to each leg of the "Y" junction/crotch. The legs

shall be positioned so that they are spread open 60 degrees, 30 degrees either side of vertical.

c. The cable assembly shall be rotated about the longitudinal axis through the point were the

legs emerge from the fixture. The fixture shall be rotated through an angle of 120 degrees,

60 degrees either side of vertical at a flexing rate of 85 cycles per minute for 25,000 cycles

without electrical discontinuity. After completion of this test the cable assembly shall meet the

requirements of 3.5.1 and 4.5.3. The "Y" junction/crotch shall be then cut open an inspected for

compliance with 3.4.18 and 4.4.2.1.
