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.

    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.

Measure the capacitance between the conductor and the sol

    20、ution. Immerse the same specimen in tap water at 23 C 2 C for 1 h with each end of the cable emerging approximately 100 mm above the surface of the water. Again, measure the capacitance between the conductor and the water. The frequency applicable to both measurements shall be 1000 Hz. Measured capa

    21、citance values shall not exceed those agreed on between the cable manufacturer and the user. 4.4 Corona Resistance Affix an approximate 1200 mm specimen to a mandrel as specified in A.2 in Appendix A.

Upon completion of the aging, remove the specimen from the oven and allow to cool to room temperature. Subjec

    27、t the specimen to winding test as defined in A.4, Appendix A. On completion of the windings, there shall be no evidence of cracks, fractures, or other defects. For resistive cables, measure the resistance of the cable at room temperature before and after the test. The allowable change in resistance

    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

    30、all be no evidence of cracks, fractures, or other defects in the surface of the specimen.

    32、nd an approximate 500 mm specimen in a draft-free chamber and expose it to the tip of the inner cone of the flame, as shown in A.5 in Appendix A, for the period of time specified in Figure 1. Any combustion of the specimen must extinguish itself within the time specified in Figure 1 following the re

    33、moval of the flame. 4.9 Low Temperature Test Affix one end of an approximate 400 mm specimen to a 25 mm rotatable mandrel and attach a 4.5 kg mass to the free end. Subject the specimen, in a vertical position (i.e., with the mass freely hanging), to the temperature specified in Figure 1 for a period

    34、 of 4 h. Without removing the sample from the freezing chamber, wind it a minimum of three turns onto the rotatable mandrel at a speed of one turn/second. There shall be no evidence of cracks, fractures, or other defects. NOTE: If the test device is precooled, a freezing time of 2 h is sufficient. 4
