RESULTS
Results from the burn segment of the test
indicated ductile iron poles showed no signs
of damage and fully supported the tension
load throughout the burn period.
Results from the full-scale bending test
showed the ductile iron poles were able to
sustain a 6,500-pound load before shearing
after burn, which is greater than twice the
NESC requirement of 2,950 pounds.
SUMMARY OF CONCLUSIONS
This two-phase test concluded that not only
were ductile iron utility poles undamaged after
a burn test, but the burned poles were then able
to sustain well above-average load tests. This
indicates that ductile iron poles would be able
to withstand the heat and maintain structural
integrity during a wildfire.
