MIL-DTL-3885G
4.5.2 Soldering. Soldering inspection shall be performed during the manufacturing
process using a minimum 4X magnification. All connections shall be soldered and meet the
requirements of 3.8.2.
4.5.3 Pull test. Cable assemblies shall be subjected to a static load, which shall be applied
between the connector and cable with at least two feet of cable subjected to the load. The pull
shall be applied parallel to the axis of the cable. A static load of not less than 20 pounds shall be
applied to cable assemblies having cable of 0.5-inch diameter or less. Cable assemblies having a
cable diameter exceeding 0.5 inch and less than 0.75 inch shall be subjected to a static load of 40
pounds. Cable assemblies having cable diameters over 0.75 inch shall be subjected to a static
load of 60 pounds. The pull test shall be performed on each end terminated with a connector.
The cable assemblies shall meet the requirements of 3.8.3 following the test.
4.5.4 Pull test on connector components. Terminals crimped to tinsel conductors and
crimped sleeves inserted into a connector shall be subjected to a three-pound minimum pull.
Terminals crimped to stranded or solid conductors shall be subjected to a 12-pound pull. Taper
pins inserted into a connector shall be subjected to a 10-pound pull-out force. Tested components
shall meet the requirements of 3.8.4.
4.5.5 Immersion. The cable assemblies shall be immersed in three feet of water at room
temperature for a period of one hour. Cable assemblies with a watertight connector on one end
only and less than three feet long shall have the watertight connector immersed to a depth not less
than 75 percent of the length of the cable assembly. The cable assemblies shall meet the
requirements of 3.8.5.
4.5.6 Durability. Measure the force required to connect and disconnect the connectors
prior to and following the durability test. The connectors shall be mated and unmated to their
mating connector or like (hermaphroditic) connectors 500 times and shall meet the requirements
of 3.8.6.
4.6 Service tests.
4.6.1 Grind test. Molded and potted components shall be ground down to one inch, or
one half of the component thickness, whichever is less. Ground surfaces shall be examined for air
bubbles and other irregularities that are caused by poor molding or potting procedures or
materials. Grinding shall be performed using silicon carbide-coated abrasive sheets in accordance
with ANSI B74.18, grit size 150 to 220. An equivalent abrasive is acceptable. The assembly
shall meet the requirements of 3.9.1.
4.6.2 Low-temperature flex-life. The cable assembly containing molded sections or heat-
shrunken transitions shall be aged in a circulating air oven for a minimum of 48 hours at
71 ±1 °C. The cable assembly shall then be conditioned for a minimum of 48 hours at the lower
limit of the cable operating temperature range. If not specified, the temperature shall be
-55 ±1 °C. This temperature shall be continuously recorded during conditioning and testing.
Each crotch or molded section shall be held in a mechanical device so that the portion of the cable
entering the molded section flexes when the cable is flexed. The cable shall be flexed
mechanically. Any part of a mechanical device that will be in contact with the test specimen shall
