7、rbon which will pass the following test requirements: The material shall adhere closely to, but strip readily from the conductors, leaving them reasonably clean and in suitable condition for soldering. Insulation thickness shall be in accordance with para 3.2.1 and shall be determined by measuring t
8、he diameter over the insulation, then removing the insulation and measuring the diameter of the conductor. Half of the difference of the two measurements shall be considered as the wall thickness. 3.3.1 High Temperature Resistance One inch (25 mm) of the insulation shall be removed from each end of
9、a 24 in (610 mm) sample of the finished cable. The sample shall be suspended around a cylindrical mandrel having a diameter of 4.5 in (114 mm). Each end of the conductor shall have suspended from it a weight of 1 lb (0.45 kg). This condition shall be maintained for 168 h at 248 - 252 C in a circulat
10、ing air oven. When cool, the weight shall be removed from the specimen and it shall be taken off the mandrel, bent in the reverse direction around a mandrel of 3.0 in (76 mm) diameter at a rate not to exceed one complete turn/min and then be subjected to the dielectric test (para 3.3.2). 3.3.2 Diele
11、ctric Test A specimen of the cable 24 in (610 mm) long shall be formed into a loop. One inch (25 mm) of the insulation shall be removed from each end of the wire and the ends twisted together. The loop thus formed shall be immersed in water containing 5% salt by weight at room temperature, so that n
12、ot more than 6 in (152 mm) of each end of the specimen protrudes above the solution. After being immersed for 5 h and while still immersed, the specimen shall withstand the application of 1000 V (rms) at 60 Hz frequency between the conductor and the water for 1 min without rupture of the insulation.
13、 ENGINEERING MATERIAL SPECIFICATION ESF-M1L111-A Page 3 of 3 Copyright 2010, Ford Global Technologies, Inc. 3.3.3 Oil Resistance A specimen 24 in (610 mm) long shall be immersed to within 1.5 in (38 mm) from the ends in a mixture of equal parts of kerosene and engine lubricating oil at a temperature
14、 of 50 +/- 2 C for a period of 20 h. The sample shall then be removed from the solution, examined for deterioration of the insulating compound, and gaged for swelling. The outside diameter of the insulation of the cable shall not increase more than 15%. The sample shall then be bent around a mandrel
15、 3.0 in (76 mm) in diameter and checked for cracking; after the bend test the cable shall be given the dielectric breakdown test (para 3.3.2). 3.3.4 Cold Resistance A straight specimen shall be reduced to a temperature of -40 C at a rate not to exceed 50 C/min. After maintaining this temperature for
16、 3 h and while still at this low temperature, the cable shall be wrapped around a mandrel 3.0 in (76 mm) in diameter for 180 at a uniform rate of 1 turn in 10 s. The insulation shall be removed for a distance of 1.0 in (25 mm) from each end of the specimen and the specimen subjected to the dielectri
17、c test (para 3.3.2). 3.3.5 Flame Test A 24 in (610 mm) specimen shall be suspended in a vertical position within a partial enclosure which allows a flow of sufficient air for complete combustion but is free from drafts. The tip of a 2 in (50 mm) gas flame with an inner core one-third its height shal
18、l then be applied to the end of the specimen for 15 s. After removal of the flame the specimen shall not continue to burn for more than 30 s. 3.3.6 Abrasion Resistance, min 6 in (152 mm) of tape (SAE J 1128, Bracket A, 1 lb (0.45 kg) weight) 4.
