Qualification Sizes
: FL2500-2 qualifies FL2500-0, -1, -2, -3 and -4.
Note 1: Tensile Strength & Secant Modulus
Calculate Tensile Strength and Secant Modulus based on wall thickness of jacket only.
Note 2: 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.
Note 3: 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.
Note 4: 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.
