Unless otherwise specified, all specimens shall be the entire length of wire conductors subjected to continuous spark testing with voltage set at 1500 volts, AC.6.2.5.1 Apparatus6.2.5.1.1 Spark Tester

35、A transformer of sufficient capacity to maintain the test voltage specified in the detailed specification under all normal conditions of leakage current shall be used. The core of the transformer and one end of the secondary winding shall be connected to ground. A voltmeter shall be so located in th

36、e circuit that it will indicate at all times the actual test voltage applied. The spark tester shall not be simultaneously connected to more than one electrode.6.2.5.1.2 ElectrodeAn electrode which makes direct mechanical contact with the surface of the insulation of the wire or cable undergoing tes

37、t shall be used. A pipe, coiled spring or the like shall not be acceptable. If the link bead-chain type of electrode is used, the bottom of the metal electrode enclosure shall be “V”-shaped.

The test voltage shall be as specified in the detailed specification. The specimen shall be attached to the electrode and the electrode

42、 connected to one lead of the transformer secondary. Both ends of the conductor of the specimen, the other secondary lead and the transformer core shall be grounded. A direct connection shall be made between the ground of the conductor at the take-up end of the transformer secondary ground. The volt

A 25 mm (1 inch) length of insulation shall be removed from each end of a 600 mm (24 inch) sample of each size of finished insulated conductor and the two ends t

46、wisted together. The loop thus formed shall be immersed in water containing 5% salt by weight at room temperature so that not more than 150 mm (6 inch)of each end of the sample protrudes above the solution. After being immersed for 5 h and while still immersed, the sample shall withstand the applica

47、tion of 1000 V rms at 50 to 60 Hz between the conductor and the solution for 1 min without failure of the insulation.SAE INTERNATIONAL J1067 OCT2016 Page 6 of 96.2.7 Cold Bend TestUsing a specimen of each of the insulated conductor sizes employed in the cable and a mandrel size as identified in Tabl

49、ated conductors shall pass the pinch test outlined in SAE J1128. Note that while this test does not specify elevated temperature in the way that a UL deformation test would, the heat aging requirement contained in the above physical properties section is considered fully adequate for the application.6.2.9 Abrasion ResistanceThe cable jacket shall be subjected to the sandpaper abrasion resistance test outlined in SAE J
