Check for the latest revision. 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). 4.2.1 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. 4.2.1 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. 4.2.1 Flammability: Ten assemblies shall be mounted vertically, closed end down, in a draft-free chamber. An 8 x 8 inch piece of tissue paper conforminf to UU-T-450 shall be suspended taut and centered 9 ½ inches below the test specimen, a minimum of ½ inch from the table top, in such a manner that any dripping particles will fall on the tissue paper. A standard 1/8” Bunsen burner shall be adjusted to produce a blue flame approximately 1” high. The tip of the flame shall be applied 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 within the time specified or ignition of the tissue paper caused by dripping of flaming or glowing particles shall be cause for rejection. |
