APPLICATION This specification was released originally for material used for maximum performance in tractor and automotive type engines. 3. REQUIREM

4、ENTS 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). 3.1 CABLE CONSTRUCTION 3.1.1 Conductor The conductor shall consist of 60 ends of ECG 150 strand glass conductive

5、 roving uniformly treated with carbon. An optional binder yarn, which consists of ECG 150 1/0 Z 39 tpm, may be used as a manufacturing aid. This is covered with ECG 75 1/0, 1 end natural glass braid using 8 heads on a 16 head braider, with 28 +/- 4 picks/100 mm and a basket (one over one) weave. Ove

6、r the braid there shall be extruded high temperature thermosetting conductive silicone. The core shall then be vulcanized (thermally cured). The finished conductor shall be smooth and have a diameter of 2.44 +/- 0.13 mm, with a minimum conductive silicone wall thickness of 0.25 mm. 3.1.2 Conductor I

7、nsulation The conductor shall be coated with a covering of silicone rubber, placed concentrically within 0.25 mm around the conductor. The diameter of the insulated conductor must not exceed 6.48 mm. The minimum diameter is limited only by the performance tests hereinafter required. ENGINEERING MATE
