Tensile Strength & Secant Modulus
Calculate Tensile Strength and Secant Modulus based on wall thickness of jacket only.
Immersion Leak Resistance
Prepare 3 test assemblies insulated with FL2500-2 as follows: Construct a 3-wire to
3-wire inline splice in any suitable manner (crimped, soldered, twisted or welded).
Splice an AWG 14 and two AWG 12 wires to an AWG 14 and two AWG 12 wires.
Each wire shall be approximately 12 inches long. The wire insulation shall be
crosslinked polyolefin (TXL) and the conductor shall be bare copper. Shrink a 2.5-inch
length of FL2500-2 over the splice area using a forced air oven set at 150 ± 3°C
(302 ± 5°F)
for 5 minutes. Allow the test assemblies to cool to room temperature and
immerse them, except for the ends, in a 5% salt solution for 24 hours at room
temperature. Apply 50 volts d-c to the immersed specimens and measure the leakage
current.
Thermal Cycling
Prepare 3 splice assemblies in accordance with Note 2 and subject them to 5 thermal
cycles. One cycle consists of 30 minutes in a 5% saline solution at 5 ± 5°C and 30
minutes at 130 ± 5°C with a maximum of 2 minutes between temperatures. Specimens
shall then be allowed to cool to room temperature for one hour minimum and shall be
measured for leakage current in accordance with Note 2.
Thermal Aging
Prepare 3 splice assemblies in accordance with Note 2 and hold for 168 hours at 130 ±
5°C. The specimens shall then be allowed to cool to room temperature for one hour
minimum and shall be measured for leakage current in accordance with Note 2.

Note 5:
Flammability
Prepare 6 splice assemblies in accordance with Note 2. Suspend a 24 in. (600 mm)
sample of the finished spliced cable taut in a horizontal position within a partial
enclosure which allows a flow of air sufficient for complete combustion, but is free from
drafts. Use a flame spreader apparatus as described in SAE J1128. Position the top of
the 2 in. (50 mm) vertical flame so that the top of the flame just touches the suspended
specimen, with the flame spreader parallel to the axis of the spliced cable. Test 3
separate specimens with the flame in each of two positions: 1) Center the flame
spreader under the edge of the heat-shrinkable tubing such that the flame is applied to
approximately 1 in. (25 mm) of tubing and 1 in. (25 mm) of wire on the side with the
single wire and 2) Center the flame spreader under the center of the approximately 2
inch long splice. Apply the flame for 15 seconds, as described in SAE J1128,. After
removal of the Bunsen burner flame, the splice and adhesive shall not continue to burn
for more than 30 seconds.
Fluid Resistance
Prepare 9 splice assemblies in accordance with Note 2 and immerse 3 assemblies in
each of the fluids specified for the time and temperature given. Measure leakage current
in accordance with Note 2.
Acceptance tests shall consist of:
Dimensions
Tensile Strength
Ultimate Elongation
Heat Shock
Note 6:
Acceptance tests shall be performed on each lot of tubing or an a skip-lot basis per a
statistically justified control plan determined by the TRM Division of Tyco Electronics.
Qualification tests shall consist of all the tests in this Specification Control Drawing.
