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.
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 -40°C and 30 minutes at 135°C 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.
Thermal Aging
Prepare 3 splice assemblies in accordance with Note 2 and heat for 1000 hrs at 150°C.
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.
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
