3.1.2 Water Immersion (Bellcore 5.3.5.1)
The cold impact tested samples #17 & 18 were submerged in tap water at a depth of 24 inches (61 cm) at
a temperature 76° F ± 2° F (24° C ± 1° C) for 14 days. During testing, 48 V DC of power from a current
limited short tester was applied to all service wire pairs to simulate working pairs and to detect a
possibility of an electrical short in each working pair. The IR was measured at 100 V DC after one hour
and every other day thereafter. At the end of the test, the IR between any two wire pairs and all pairs to
shield should be at least 1 x 10
8
ohms. Both samples passed the test and the lowest IR was at least two
orders of magnitude above the requirement.

data is the overall average of all data measured for each sample. Minimum data is the lowest IR data
obtained for each sample

3.1.3 Thermal Shock (Bellcore 5.3.5.2)
The samples #1-16 from the temperature cycling with high humidity test and samples #17 & 18 from the
water immersion test, were subjected to fifteen 16 hour temperature cycles between -40° F (4.4° C) and
140° F (60° C). The dwell time at each extreme temperature and the transition time between the two
extreme temperatures is four hours each. During aging, 48 volts of power from a current limited short
tester was applied to all service wire pairs to simulate working pairs and to detect a possibility of an
electrical short in each working pair. Applying 48 volts of power during the thermal shock test was not
required by the Bellcore.
At the conclusion of the test, all samples were examined for any deterioration of the external closure
material. No sign of deterioration was found. The insulation resistance was measured on each sample
with samples having insulation resistance values above the minimum requirement of 1 x 10
8
ohms.

3.1.4 Freeze/Thaw Cycling in Water (Bellcore 4.3.6 & 5.3.6)
In this test, aged samples were used rather than preparing new samples as specified by the Bellcore. The
test samples included sixteen samples (samples #1-16) that had gone through a series of accelerated aging
tests as described in sections 3.1.1 & 3.1.3, and two samples (samples #17 & 18) that had gone through
cold impact (section 3.4.1) and several accelerated aging tests (sections 3.1.2 & 3.1.3). Samples #1-16
were immersed in water to a depth of 32 inches and samples 17 & 18 were under 12 inches of sand
saturated with water. Weights were put on top of samples #1-16 to keep them submerged in the water
tank throughout the test. The samples were cycled between -40° F (-40° C) and 158° F (70° C) for 50
cycles (59 days). The cycle time was 28 hours, 10 hours at each extreme temperature and four hour
transition time between the hot and cold temperature extremes. During aging, 48 volts of power from a
current limited short tester was applied to all service wire pairs to stimulate a working pair and to detect a
possibility of an electrical short in each working pair. Applying 48 volts of power during the freeze/thaw
cycling test was not required by the Bellcore. Again, there was no sign of deterioration of the closure
material at the end of test and all samples had insulation resistance values greater than the minimum
requirement of 1 x 10
8
ohms.
