As an alternate method, conductor area may also be determined in accordance with ASTM B 263. 3.3.2 The strands shall be bunched per ASTM B 174. The maximum

7、lay length shall be as specified in ASTM B 174, Table 3, Column A. Conductor strand count shall comply with Table 1 of this specification. Missing strands are not allowed. 3.3.3 Conductor resistance shall be measured by stripping 30 mm of insulation from each end of a 1050 mm cable (use of a longer

8、specimen is optional). Solder (optional) 25 mm along each end of the specimen. Condition the specimen for a minimum of 4 hours at 23 +/- 5 C. Measure the unsoldered length, the ambient temperature, and the resistance of the specimen. Calculate the resistance per meter. Calculate the resistance at 20

Where striping is specified, the stripe shall be a minimum of 0.3 mm. wide, but not more than 15% of the circumferen

11、ce of the wire. The stripe shall be of the same material as the insulation. If the insulation is dyed or painted, all the cable quality tests in section 3.4 and 3.5 must be performed on the finished product. The insulation and the color may show no evidence of peeling or cracking and must conform to

12、 the color tolerances specified. 3.4.2 The insulating material shall be flame retardant, homogeneous, cross-linked polyethylene, similar to SAE J1128, Type TXL. The material shall adhere closely to, but strip readily from the conductors, leaving them free of insulation and in suitable condition for

13、applying terminals. 3.4.3 Insulation thickness shall comply with the requirements of Table 2. Measure the minimum wall thickness of a 2000 mm specimen with an optical measurement device accurate to +/- 0.01 mm (other devices may be used but the referee method will be the optical device).

The minimum insulation thickness shall comply with the values listed in Table 2. 3.5 CABLE QUALITY (TESTS) (SAE J1128) The Mechanical Properties, Dielectric, Flame, Crosslinking, and Cold Bend Tests shall all be conduct

15、ed in accordance with SAE J1128, Type TXL. Note: The following paragraphs shall be tested in accordance with SAE J1128, but with exceptions to the requirements as indicated. 3.5.1 Cable Diameter Measure the outside diameter of a 2000 mm specimen with an optical measurement device accurate to +/- 0.0

16、1 mm (other devices may be used but the referee method will be the optical device) by taking a minimum of 2 readings approximately 90 apart at each cross section. Move the sample approximately 400 mm and repeat the procedure for a total of five cross-sections. The mean of all the readings will deter

17、mine the outside diameter of the cable. The outside diameter will conform to the values listed in Table 2. 3.5.2 Pinch Test (SAE J1128) Values as specified in Table 3 of this document. 3.5.3 Heat Shrinkage (FLTM BB 101-15) Use a 200 mm sample for the test. The maximum insulation shrinkage shall not

Abrasion resistance requirements are specified in Table 3. 3.5.6 Long Term Aging (For Initial Qualification Only) Strip 25mm of insulation from each end of a

20、 600 mm specimen. Condition the specimen for 3000 hours in a circulating air oven at a temperature of 125 +/- 2 C. Remove the specimen from the oven and allow it to remain at 23 +/- 5 C for a minimum of 4 hours. After this time perform one of the following tests: 1) Rotatable mandrel-fix one end of

21、the specimen to the mandrel and attach a weight to the free end of the specimen. Wind at least 1/2 turn, but no more than 3 turns, around the mandrel at a uniform rate of 1 turn in 10 seconds.

22、 turns, around the mandrel. Subject the specimen to the Dielectric test. There shall be no dielectric breakdown of the insulation. 3.5.7 Fluid Compatibility Remove 25 mm of insulation from each end of a 1000 mm specimen of cable and twist the two ends together. Measure the outside diameter as descri

23、bed in 3.4.1. Immerse one specimen in each of the fluids described in Table 5 for 20 hours. A maximum of 50 mm of each end of the specimen may protrude above the fluid. Withdraw the specimen and remove any excess fluid. Allow the specimen to remain at 23 +/- 5 C for approximately four hours. After t

24、he elapsed time, measure the outside diameter of the specimen and compute the percent diameter change. Perform one of the following tests on the specimen: 1) Rotatable mandrel-fix one end of the specimen to the mandrel and attach a weight to the free end of the specimen. Wind at least 1/2 turn, but

25、no more than 3 turns, around the mandrel at a uniform rate of 1 turn in 10 seconds.
