Note: The assemblers of electrical wire harnesses shall use the bulk wire suppliers as shown in the Ford Motor Company Materials Approved Source List. 3. REQUIR

4、EMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.4 CONDUCTOR 3.4.1 Unless otherwise specified, the individual strands of the conductor shall be soft or annea

5、led copper conforming to ASTM B 3, except strand dimensions. These dimensions shall be controlled to yield the cross-sectional area listed for the conductor of the finished cable per Table 1. Conductor area shall be determined by measuring individual strand diameters and calculating the sum of the i

6、ndividual strand areas. As an alternate method, conductor area may also be determined in accordance with ASTM B 263. For this procedure, let k=2 in accordance with ASTM B 174, para. 12.3. 3.4.2 The strands shall be bunched per ASTM B 174. The maximum lay length shall be as specified in ASTM B 174 Ta

Missing strands are not allowed. 3.5 INSULATION 3.5.1 The color of the insulation shall be specified on the engineering drawing of the component utilizing this material. Base and stripe colors shall correspond to SAE J 1128. Where st

8、riping is specified, one or two stripes may be used. The width of the stripe(s) shall be a minimum of 0.3 mm but not more than 15% of the circumference of the wire. If the insulation is dyed or painted, all cable quality tests in Section 3.6 must be performed on the finished product. The insulation

9、and the color may show no evidence of peeling or cracking and must conform to the color tolerances specified with the exception of quality tests 3.6.2 and 3.6.3.

10、.5.2 The insulating material shall be flame retardant, homogeneous, cross-linked polyethylene, similar to SAE J 1128, Type TXL. The material shall adhere closely to, but strip readily from the conductors, leaving them free of insulation and in suitable condition for applying terminals. 3.5.3 Insulat

11、ion Mechanical Properties These tests shall be conducted in accordance with SAE J 1128, for Type TXL, except that the insulation shall be conditioned for 24 +/- 2h at 60 +/- 2 C prior to taking original measurements and that the aging test temperature shall be 160 +/- 2 C. 3.5.4 Insulation thickness

12、 shall comply with the requirements of Table 2. Insulation thickness shall be measured with an optical device accurate to at least 0.01 mm or a pin micrometer with a diameter of 0.5 mm. The test method for determining minimum insulation thickness at any point shall be in accordance with ANSI/UL-1581

13、, Reference Standard for Electrical Wires, Cables and Flexible Cords, Paras 240 through 250.11. In case of dispute, the referee method shall be the optical device. 3.6 CABLE QUALITY TESTS The following tests: Dielectric Test, Cold Bend Test, Flame Test, Fluid Compatibility Test, Ozone Resistance, Pi

14、nch Test, Abrasion Resistance, Cross linking, and Strip Force shall be conducted per SAE J 1128 for type TXL cable. The tests listed below shall be conducted in addition to the tests listed above. 3.6.1 Cable Diameter Measure the outside diameter of a 2000 mm specimen with an optical measurement dev

15、ice accurate to +/- 0.01 mm (other devices may be used but the referee method will be the optical device) by taking a minimum of 2 readings approximately 90 apart. Move the sample approximately 400 mm and repeat the procedure for a total of five cross-sections. The mean of all the readings will dete

16、rmine the outside diameter of the cable. The outside diameter will conform to the values listed in Table 2. 3.6.2 High Temperature Resistance 25 mm of insulation shall be removed from each end of a 600 mm sample of finished cable. The sample shall be suspended around a cylindrical mandrel having a d

17、iameter specified in Table 3. The weight specified for the Cold Bend Test above shall be suspended from each end of the conductor. This condition shall be maintained for 168 h in a mechanical convection oven at a temperature of 165 +/- 2 C. When cooled to room temperature, the specimen shall be remo

18、ved from the mandrel and wrapped in the reverse direction around a mandrel of diameter specified in the Cold Bend Test using the Cold Bend Test method (except reverse bend conducted at room temperature). No cracks or splits in the insulation are permitted. After the reverse mandrel wrap the specimen

19、 shall be subjected to the Dielectric Test.
