Example: #16 gage ESF-M1L58-A. 3.3 COLOR The color of the vinyl cover shall be specified on the engineering drawing and/or release by a numerical suffix following the lett

5、er suffix of the materials desired. The numerical color coding suffixes shall correspond to the following: 0 Black 5 - Green 1 Brown 6 - Blue 2 Red 7 - Violet 3 Orange 8 - Gray 4 Yellow 9 - White or Natural ENGINEERING MATERIAL SPECIFICATION ESF-M1L58-A ESF-M1L59-APage 2 of 6 Copyright 2002, Ford Gl

6、obal Technologies, Inc. Example: #16 gage ESF-M1L58-A1 shall designate a stranded 16 gage, brown vinyl covered, soft or annealed bare copper conductor, corresponding to the requirements of this specification. The first color coding numerical suffix shall be the base or body color of the finished cab

7、le and the second number shall designate the tracer or other auxiliary marking. 3.4 CABLE QUALITY Shall meet all of the requirements listed herein and must be equal to the original approved purchase sample. ESF-M1L58-A similar to M-1L17-C ESF-M1L59-A similar to M-1L17-D 3.5 WIRE QUALITY The strands

8、of the conductors prior to stranding shall consist of the following grades of wire: ESF-M1L58-A: ESF-M2L1-A, soft or annealed bare copper wire ESF-M1L59-A: ESF-M2L3-A, soft or annealed tinned copper wire 3.6 CABLE CONSTRUCTION See Tables I & II The cross sectional area of stranded conductors shall n

9、ot be less than 98% of the values specified in Table I. 3.7 INSULATION QUALITY The insulating material shall be a good grade vinyl chloride copolymer which will pass the following test requirements: The material shall adhere closely to, but strip readily from the conductors, leaving them reasonably

10、clean and in suitable condition for soldering. Insulation thickness shall be in accordance with Table II for the various wire sizes and shall be determined by measuring the diameter over the insulation, then removing the insulation and measuring the diameter of the conductor. Half of the difference

11、of the two measurements shall be considered as the wall thickness. ENGINEERING MATERIAL SPECIFICATION ESF-M1L58-A ESF-M1L59-APage 3 of 6 Copyright 2002, Ford Global Technologies, Inc. 3.7.1 Mechanical Properties A test specimen of the thermoplastic insulation prepared as in the SAE J200 section on s

12、ampling shall be used. The dumbbell cut sample shall have marks placed upon it 50 mm apart. The sample shall then be stretched at the rate of 305 mm/min. The tensile strength shall be calculated upon the original cross section of the test specimen before stretching. Testing shall be conducted at 23

13、+ 2 C. Care should be exercised in cutting samples to obtain uniform cross section. The properties shall be as follows: Tensile Strength, min 15.9 MPa Elongation, min 125% 3.7.2 High Temperature Resistance Remove 25 mm of insulation from each end of a 610 mm sample of the finished cable. The sample

14、shall be suspended around a cylindrical mandrel having a diameter specified in Table III. Each end of the conductor shall have suspended from it, the weight shown in Table III. This condition shall be maintained for 120 h in a mechanical convection oven maintained at a temperature of 135 - 137 C. Wh

15、en 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 the diameter specified for the bend test in Table III at a rate not to exceed one complete turn/min and then be subjected to the dielectric test, para 3.7.3

16、. 3.7.3 Dielectric Test A specimen of the cable 610 mm long shall be formed into a loop. Remove 25 mm of insulation from each end of the wire and twist the ends together. The loop thus formed shall be immersed in water containing 5% salt by weight at 23 + 2 C, so that not more than 152 mm of each en

17、d 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 volts (rms) at 60 Hz between the conductor and the water for 1 min without rupture of the insulation. 3.7.4 Oil Absorption Test A specimen 610 m

18、m long shall be immersed to within 38 mm from the ends in a mixture of equal parts of M14J167 hydrocarbon thinner and ESE-M2C36 heavy duty lubricating oil at a temperature of 48 - 50 C for a period of 20 h. The sample shall then be removed from the solution, examined for deterioration of the insulat

19、ion 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 (Table III) and checked for cracking. After the bend test, the cable shall be subjected to the dielectric test, para 3.7.3. ENGINE

20、ERING MATERIAL SPECIFICATION ESF-M1L58-A ESF-M1L59-APage 4 of 6 Copyright 2002, Ford Global Technologies, Inc. 3.7.5 Cold Bend Test 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 3 h and while still at this low t

21、emperature, the cable shall be wrapped around the mandrel specified in Table III for 180 C at the uniform rate of one turn in 10 s. The insulation shall be removed for a distance of 25 mm from each end of the specimen and the specimen subjected to the dielectric test, para 3.7.3. 3.7.6 Flame Test A

22、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 50 mm gas flame with an inner cone one-third its height shall then be applied to the end of the specimen for 15 s.

23、After removal of the flame the specimen shall not continue to burn for more than 30 s. 3.7.7 Abrasion Resistance As per Table IV (FLTM BO 023-01) ENGINEERING MATERIAL SPECIFICATION ESF-M1L58-A ESF-M1L59-APage 5 of 6 Copyright 2002, Ford Global Technologies, Inc.
