SCOPE The material defined by this specification is a low tension stranded cable, perlfluoro alkoxyl alkane (PFA) insulated conductor. The ca

3、ble is similar to ISO 6722 with a thin wall insulation thickness. It is a spirally wound shielded and twisted wire with a 90% shield cover and a helix angle of 10%. 2. APPLICATION This specification was released originally for materials used in automotive electrical harnesses. Note: The assemblers o

4、f electrical wire harnesses shall use the bulk wire suppliers as shown in the Ford Motor Company Approved Source List. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials

5、(WSS-M99P1111-A). 3.3 CABLE 3.3.1 Specimen Length 1.2 m 3.3.2 The maximum outside diameter shall be determined by taking measurements at three points along the conductor length separated by at least 100 mm and recording the greatest overall diameter at each point. No single value shall exceed the ma

6、ximum overall diameter as specified in Table 2. 3.4 CONDUCTOR 3.4.1 The conductor of all cable classes shall consist of bunched or stranded soft annealed copper wire. 3.4.2 Specimen Length 1.2 m 3.4.3 Three sections 10 mm long and separated by at least 400 mm shall be cut from the specimen. Carefull

7、y remove the conductor without deformation of the insulation. 3.4.4 The conductor diameter shall be determined by measuring the inside diameter of the insulation taken at three points separated by at least 100 mm and recording the maximum inside diameter at each point. The measurements shall be made

8、 with an optical device accurate to at least 0.01 mm. No value shall exceed the maximum diameter of the conductor specified in Table 2.

9、ay be determined by measuring individual strand diameters and calculating the sums of the individual strand areas. As an alternate method, conductor area may also be determined in accordance with FLTM BB 105-01 or by measuring the resistance in accordance with table 1. 3.4.6 The strands shall be bun

10、ched and the maximum lay length shall be a maximum of 50 times the conductor diameter. Minimum number of wires shall comply with Tables 1 and 2. Maximum variation between individual strand diameters must not exceed 10 percent per the following: Variation = max strand dia - min strand dia _ min stran

11、d dia Missing strands are not allowed. 3.4.7 Elongation (ASTM B 3) for d 15% for d 0.287 mm e 20% where: d = individual strand diameter e = elongation of individual strand 3.4.8 Resistivity, max 1.7544 /cm (ASTM B 193, at 20 C) 3.5 INSULATION AND SHEATHING 3.5.1 The insulating material shall be a pe

12、rlfluoro alkoxyl alkane (PFA) material, homogeneous in character. The surface shall be smooth and even without cracks, knots, blisters, or other faults. 3.5.2 The color of the cables are per the Munsell Color Coding System and shall conform to Table 3. Comparison must be made by a person with normal

13、 or corrected vision, under cool white fluorescent lighting. The surface being inspected and the tolerance set must be in the same plane. Cable samples must be placed flat, overlapping the color standard. Color tolerance Reference Sets are available from SAE, 400 Commonwealth Drive, Warrendale, PA 1

14、5096. As an alternative, the color of the cables can be per the DIN 47002 or IEC 304 and shall conform to Table 4. 3.5.3 The minimum insulation thickness shall be determined by taking measurements at three points separated by at least 100 mm and recording the minimum insulation thickness at each poi

15、nt. The thickness shall be measured with an optical device accurate to at least 0.01 mm. No single value shall be lower than the minimum insulation thickness specified in Table 2.
