CABLE DIMENSIONS The average overall diameter of finished cable shall be 5 mm, 7 mm, or 8 mm. Other sizes are acceptable and dimensional control for these will be as agreed
10、on by manufacturer and customer. Allowable tolerance for either size shall be 0.3 mm. The average overall diameter shall be determined by taking the average of five sets of measurements along a 1 m length of finished cable. Each set of measurements shall consist of the determination of the maximum a
11、nd minimum diameter at the point of measurement. 4. TEST REQUIREMENTS When tested according to the methods outlined, the ignition cables covered by this document shall be capable of complying with the applicable requirements specified herein. Test methods and requirements for cable constructions oth
12、er than those specified previously will be as agreed on by manufacturer and customer. Figure 1 defines the applicability of the test and provides specific performance criteria. NOTE: Wherever the term “room temperature” is used, it shall be defined as 23 C 5 C. NOTE: Wherever the term “full draft, c
13、irculating-air oven” is used, the air shall be completely exchanged at least 8 times per h, but no more than 20 times per h. 4.1 Spark Test When agreed upon by the manufacturer and customer, an AC spark test shall be performed on 100% of production of each ignition wire to which it is applicable (se
14、e Figure 1). Apparatus shall consist of a voltage source, electrode, voltmeter, fault-current device or system, and the necessary electrical connections. The recommended apparatus and test method shall be that described in UL 1581, Section 900. Test potential shall be 25 kV for 5 mm, 25 kV for 7 mm
15、cable, and 30 kV for 7 mm High Energy or 8 mm cable. NOTE: This test is not a qualification test but an in-process test carried out under production conditions. Alternate methods for this test may be considered provided that insulation faults are detected with the same degree of certainty. 4.2 High
16、Potential Test Refer to A.1 in Appendix A for test apparatus. Immerse an approximate 1200 mm specimen for 4 h in a salt solution (3% m/m of NaCl in water) at room temperature with the ends twisted together and emerging approximately 400 mm above the surface of the solution. Apply a test voltage of 2
17、0 kV (rms) for 30 min between the conductor and the solution. NOTE: The applied potential is to be increased from near zero at an essentially uniform rate not to exceed 500 V/s. The cable shall not break down. Then increase the voltage at a rate not exceeding 500 V/s to the following levels: 5 mm ca
18、ble - 25 kV (rms) 7 mm cable - 30 kV (rms) 7 mm High Energy cable - 35 kV (rms) 8 mm cable - 35 kV (rms) Cable breakdown shall not occur below the voltage indicated.

28、shall not exceed the values specified in Figure 1. 4.7 Test for Shrinkage This test shall apply where shrinkage of the conductor covering(s) is important with respect to the attachment of the connector. Measure the exact length (200 mm minimum) of a suitable specimen at room temperature. Place the s
29、pecimen horizontally into a full draft, circulating-air oven maintained at the temperature specified in Figure 1 for a period of 15 min. Remove the specimen, cool to room temperature, and measure the length again. Maximum shrinkage shall not exceed the values shown in Figure 1. In addition, there sh
