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

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°C
(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).

4.2.1
Heat Aging: Fifteen assemblies shall be conditioned for 1000 hours at 150
±
3°C (302
±
5°F) in a
mechanical-convection oven with an air velocity of 100 to 200 feet per minute past the specimens. After
conditioning, 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).
Altitude Immersion: Fifteen assemblies shall be immersed in a water bath containing 5% by weight of
NaCl and placed in a chamber. Wire ends, opposite the cap, shall be within the chamber, but not
submerged. The exposed wire ends shall not be sealed. The chamber pressure shall be reduced to
approximately 1 inch of mercury and maintained for 30 minutes. The chamber pressure shall then be
returned to atmospheric pressure. The insulation assistance shall be measured in accordance with 4.4.3.
This shall constitute one cycle. Two additional environment cycles shall be run. At the end of the third
cycle, the insulation resistance (4.4.3) shall be re-measured, and the dielectric withstanding voltage test
(4.4.4) shall be performed.
Corrosive effect: Two caps, as supplied, shall be placed in the bottoms of two clean ½ x 12 inches test
tubes (one cap per tube). A third tube shall be used for control. A copper-glass mirror, about 1 x ¼ inches
shall be suspended from 6 to 7 inches above the bottom of each tube by a fine copper wire attached to a
cork wrapped in aluminum foil. The corks shall tightly seal the test tubes. The lower 2 inches of each tube
then shall be placed in an oven or oil bath at 175
±
3°C for 16 hours. After cooling, the mirrors shall be
examined in a good light against a white background. Evidence of corrosion shall be areas of transparency
larger than pinholes in a mirror. Discoloration of the copper film or reduction of its thickness shall not be
considered corrosion. The mirrors shall be vacuum- deposited copper with thickness equal to 10
±
5%
transmission of normal incident light of 5000 angstroms. They shall be stored in a vacuum and shall be
used for test only if no oxide film is present and the copper is not visibly damaged.
Flammability: Specimens shall be mounted horizontally in a draft-free chamber. A standard 1/8” Bunsen
burner shall be adjusted to produce a blue flame approximately 1” high. This flame shall be applied at a
distance of 1” to the closed end of the test specimen for 10 seconds. The flame shall then be removed and
the specimen shall remain undisturbed until burning ceases. Failure of more than one specimen to
extinguish itself with 30 seconds shall be cause for rejection.
