11、ONESB-M1L85-A/B/C/D ESB-M1L86-A Printed copies are uncontrolled Copyright 2010, Ford Global Technologies, LLC Page 4 of 7 3.6.5 Cold Bend Test A straight specimen shall be reduced to a temperature of -40 C at a rate not to exceed 50 C/min. After maintaining this temperature for 3 h and while still a
12、t this low temperature, the cable shall be wrapped around the mandrel specified in Table II for 180 at the uniform rate of one turn in 10 s. The insulation shall be removed for a distance of 25 mm from each end of the specimen and the specimen subjected to the dielectric test, para 3.6.3. 3.6.6 Flam
13、e Test A bunsen burner having a 13 mm inlet, nominal bore of 19 mm, a length of approximately 102 mm, above the primary inlets, equipped with a wing-top flame spreader having a 1.6 x 51 mm opening fitted to the top of the burner shall be used. A 610 mm sample shall be suspended taut in a horizontal
14、position within a partial enclosure which allows a flow of sufficient air for complete combustion but is free from drafts. The tip of a 51 mm gas flame with an inner cone one-third its height shall than be applied to the center of the suspended cable. The time of application of the flame shall be 15
15、 s for SAE wire sizes 10 through 20, and 30 s for SAE wire size 8. After removal of the bunsen burner flame, the specimen shall not continue to burn for more than 30 s. 3.6.7 Abrasion Resistance As per Table III (SAE J1128) 3.6.8 Electrical Overload Test In an ambient temperature of 24 +/- 3 C a 152
16、4 mm sample cable suspended in air, or lying on a transite table top, shall be subjected to an overload current sufficient to raise the conductor temperature to 204 +/- 2 C and to hold it there for a period of 30 min (thermocouple to be inserted into sample conductor stranding 457 mm from one end).
17、After the overload test, cut 457 mm from each end of the cable and discard. The remaining 610 mm portion (which was in the center of the original 1524 mm sample) shall then be subjected to dielectric Test, para 3.6.3). 3.6.9 Pinch Test 25 mm of the insulation shall be removed from one end of a 914 m
18、m sample of finished cable. The specimen shall then be placed taut without stretching, on a steel anvil and be subjected to the force of a weighted 3.2 mm diameter rod. Increasing weight shall be applied to the steel rod by means of flowing water or equivalent method at the rate of 1.36 kg/min with
19、a lever advantage of 10. At the moment the insulation is pinched through, the 3.2 mm diameter rod will contact the sample conductor, and the test shall stop. The weight of the water in the receptacle shall then be recorded in kilograms. After each reading, the specimen shall be moved forward 51 mm a
20、nd rotated clockwise 90. Eight readings shall be obtained for each sample. Obtain an average by calculating the arithmetic mean of all those readings. This average shall define the pinch resistance of the wire under test and shall be no less than the minimum specified in Table IV. The pinch test app
21、aratus shall be equivalent to that shown in Fig I.
