25、nch conical flame with an inner cone approximately 1 inch in height and a temperature of 955C 30C (1751F 54F) at its hottest point. A sheet of facial tissue conforming to UU-T-450 shall be suspended taut and horizontal 9-1/2 inches below the marked point on the wire specimen in the test chamber and
26、at least 1/2 inch above the floor of the chamber. The period of application of the hot flame tip to the marked point on the wire specimen shall be 30 seconds for all sizes of wire. Observations shall include time of burning after removal of the test flame, final distance of flame travel on the wire
27、above the test mark, and presence or absence of flame in the facial tissue due to incendiary drip from the specimen.

29、 of the wire specimen in size 24 or smaller shall not be considered as failure provided the requirements for duration of flame, final distance of flame travel, and absence of incendiary dripping are met.One specimen shall be tested from each sample unit. The post-flame dielectric test of MIL-W-22759
30、 is not required for wire of this specification sheet.Immersion procedure:A 24-inch specimen, for each test fluid in table III, shall have its diameter measured and shall then be immersed to within 6inches of each end for the time and temperautre specified. During immersion, the radius of bend of th
31、e wire shall be not less than 14 nor more than 35 times the specified maximum diameter of the wire under test. Upon removal from the test fluid, the specimen shall be wiped dry and then remain for 1 hour in free air at room temperature. The diameter shall be measured and compared to the initial diam
32、eter. The insulation shall be removed for a distance of 1/2 inch from each end of the specimen. The specimen shall then be subjected to the bend test and dielectric test specified in the procedure for life cycle testing.Propellant resistance procedure: (Initial qualification test only)Specimens of f
33、inished wire, 24 inches long, shall be immersed to within 1-1/2 inches of each end in the following propellants for the specified time at normal room temperature, using a separate specimen for each propellant.During immersion, the radius of bend of the wire shall be not less than 14 nor more than 35
34、 times the specified maximum diameter of the wire under test. Upon removal from the liquids, the specimens shall remain for no more than 48 hours in free air at room temperature. The insulation shall be removed for a distance of 1 inch from each end of the specimens, and the specimens shall be subje
35、cted to the dielectric test specified for life cycle testing.Qualifying activity: The activity responsible for the qualified products covered by this specification sheet is Naval Avionics Center, Code B/714, 6000 East 21st Street, Indianapolis, IN 46219-2189.Propellant Immersion timea.
