A series of tests has recently been completed at the Federal Outdoor Impact Laboratory (FOIL) to determine the capability of currently accepted luminaire support devices to pass the new (1985) American Association of State Highway and Transportation Officials (AASHTO) breakaway criteria for luminaire supports. The report summarizes the results of those tests. Ten of the 44 devices tested passed the new velocity change criteria. It was found that the performance of transformer bases is dependent on mounting bolt torque and, in addition, may be dependent on bolt circle diameter. However, only 5 devices passed both the velocity change criteria and the stub height criteria.
A whole array of existing breakaway luminaire supports were tested using the FHWA soft-nosed pendulum test device. The pendulum nose was developed to ...
