Note 2: Immersion Leak Resistance A) Size SCT-2 Prepare 3 test assemblies insulated with SCT-2 as follows: Construct a 2-wire to 2-wire inline splice in any suitable manner (crimped, soldered, twisted or welded). Splice an AWG 18 and an AWG 14 to an AWG 20 and AWG 14. Each wire shall be approximately 12 inches long. The wire insulation shall be cross-linked polyolefin and the conductor shall be bare copper. Shrink a 2-inch length of SCT-2 over the splice area with an appropriate heat gun. Apply heat until the SCT-2 is completely recovered on the splice and the adhesive liner flows at both ends. 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 DC to the immersed specimens and measure the current leakage. B) Size SCT-4 Prepare 3 test assemblies with SCT-4 as follows: Construct a 3-wire to 3-wire to 3-wire inline splice in any suitable manner (crimped, soldered, twisted or welded). Splice three AWG 12 wires to three AWG 12 wires. Each wire shall be approximately 12 inches long. The wire insulation shall be cross-linked polyolefin and the conductor shall be bare copper. Shrink a 3-inch length of SCT-4 over the splice area with an appropriate heat gun. Apply heat until the SCT-4 is completely recovered on the splice and the adhesive liner flows at both ends. While the assembly is still hot from the recovery process, press the ends of the SCT-4 together where the wires emerge. Using parallel jaw pliers, align the wires and assure that they are completely coated with adhesive. 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 DC to the immersed specimens and measure the current leakage. Note 3: Thermal Cycling Prepare 3 splice assemblies in accordance with Note 2 and subject them to 25 thermal cycles. One cycle consists of 30 minutes at -40C and 30 minutes at 135C with a maximum of 5 minutes between temperatures. Specimens shall be allowed to cool to room temperature for one hour minimum and shall be measured for current leakage in accordance with Note 2. Note 4: Thermal Aging Prepare 3 splice assemblies in accordance with Note 2 and heat for 1000 hrs at 150C. Specimens shall be allowed to cool to room temperature for one hour minimum and shall be measured for current leakage in accordance with Note 2. Note 5: Fluid Resistance Prepare 9 splice assemblies in accordance with Note 2 and immerse 3 assemblies in each of the fluids specified for 24 hours at the specified temperature. Measure current leakage in accordance with Note 2. Acceptance tests shall consist of: Dimensions Tensile Strength Ultimate Elongation Heat Shock Qualification tests shall consist of all the tests in this Customer Drawing Customer Drawing Rev.
