Test 1
Test Date & Time: 9/14/17, 11:45 AM (23˚C, 43%)
Test Apparatus: ICAL panel under hood calorimeter
No significant damage was observed of the ductile iron poles. The pole was sent back to the client for an
enhanced structural analysis of sections of the pole that had been exposed to the fire and wind.
Summary
A ductile iron pole was tested according to a proposed standard for utility poles by exposing them to
radiative heat, convective flames, and wind. No/little damage was observed to the pole following the test.
