126.96.36.199. Procedure B: Three specimens, prepared and measured in accordance with 4.3.1, shall be conditioned for
1000 hours in a 150 ± 3
°C (302 ± 5°F) mechanical-convection oven in which air passes the specimens at a
velocity of 100 to 200 feet per minute. After conditioning, the specimens shall be removed from the oven,
cooled to room temperature, and tested for tensile strength and ultimate elongation in accordance with
Solvent Resistance: Three specimens, prepared and measured in accordance with 4.3.1, shall be
completely immersed in each of the solvents listed in the applicable section of Table 1 for 24 hours at 25 ±
°C (77 ± 5°F). The volume of the fluid shall be not less than 20 times that of the specimens. After
conditioning, the specimens shall be lightly wiped, and then air-dried for 30 to 60 minutes at room
temperature. The specimens shall then be tested for tensile strength and ultimate elongation in accordance
Test Procedures – Finished Caps
Test Assembles: The test assembles shall consist of fifty-five crimped stub splices made in wire
confirming to MIL-W-81044/12 or MIL- 16878/4. Leads shall be 10 ± 1 inches long, and shall be of the
gauge listed below for the cap for which qualification is desired. Caps shall be installed in accordance with
Thermofit Assembly Procedure (see sheet 6).
Number of Wires/Splice
Wire Gauge (AWG)
Dimensions And Dimensional Recovery: Five specimens, as supplied, shall be measured for dimensions in
accordance with ASTM D 876. The specimens shall then be conditioned for ten minutes in a 200 ± 5
(392 ± 9
°F) oven, quenched in water in less than 35°C (95°F) for at least 30 seconds, wiped dry, and the
appropriate measurements taken.
Insulation Resistance: The specimen shall be immersed to within 3 inches of the lead ends in a water bath
containing 5% by weight of NaCl for a minimum of 30 minutes after which time the insulation resistance
shall be measured between the salt solution and the test leads. The test potential shall be 500 volts D.C.
The readings shall be taken after an electrification time of one minute.
Dielectric Withstanding Voltage: The specimen shall be immersed to within 3 inches of the lead ends in a
water bath containing 5% by weight of NaCl for a minimum of 30 minutes after which time the potential
between the salt water and the test leads shall be raised from 0 to the specified voltage at a rate of 500 volts
per second. This potential shall be maintained for one minute and the voltage reduced to 0.
Temperature Cycling: Fifteen assemblies shall be subjected to 200 cycles. Each cycle shall consist of 20
minutes at 135
°C (275°F) and 5 minutes at 240°C (400°F) in mechanical-convection ovens with an air
velocity of 100 to 200 feet per minute past the specimens. The specimens shall be subjected to 20 cycles
per day and shall be maintained at 25
± 5°C (77 ± 9°F) between test days. After the last cycle, the
specimen shall be cooled to 25
± 5°C (77 ± 9°F) within one hour and tested for insulation resistance (4.4.3)
and dielectric withstanding voltage (4.4.4).
