23、y test of MIL-W-22759 shall be modified for the wire of this specification sheet as follows: The specified test burner shall be used without the wing top flame spreader and shall be adjusted to furnish a 3-inch conical flame with an inner cone approximately 1 inch in height and a temperature of 955C
24、 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 at least 1/2 inch above the floor of the chamber. The period of application of the hot flame
25、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 above the test mark, and presence or absence of flame in the facial tissue due to incendiary
26、drip from the specimen. Requirements shall be:Breaking 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 samp
27、le unit. The post-flame dielectric test of MIL-W-22759 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 temperature
28、 specified. During immersion, the radius of bend of the 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 diame
29、ter shall be measured and compared to the initial diameter. 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.Duration of after-flame 3
30、seconds (max)Flame travel 3.0 inches (max)No flaming of tissueCopyright SAE International Provided by IHS under license with SAENot for ResaleNo reproduction or networking permitted without license from IHS-,-400 Commonwealth Drive, Warrendale, PA 15096-0001WIRE, ELECTRICAL, FLUOROPOLYMER-INSULATED,
