Classification test — the transverse bending and torsional test described in Clause 7.3, used to verify the design procedure for poles defined by class.
Coating — a chemical that forms a coat on the surface of concrete.
Note: The chemical groups that provide coatings include acrylics, epoxies, polyurethanes, and silicones,
Cracking load — the transverse bending moment or transverse tip load at which the first circumferential crack of a width of 0.1 mm (0.004 In) or larger occurs. Where test data are not available, the cracking load is defined as the load at which the tensile bending stress anywhere along the tension face of a pre-stressed pole equals the applied pre-stress plus the assumed tensile stress of the concrete.
Equivalent projected area (EPA) — the projected area that would have the same drag if its coefficient of drag were 1.
Note: The EPA is a measurement used by the manufacturers of specially shaped products such as luminaires and antennas.
Failing load — the heaviest load in a classification test that can be sustained for a minimum of 15 S. Failing torque — the highest torque in a torsion test that can be sustained for a minimum of 15 s.
Helical reinfoicement — wire reinforcement continuously wrapped around the main longitudinal reinforcement to reinforce a pole in a circumferential direction.
High torsional load — tosional load above the ultimate torsional capacity for a given class. Minimum breaking strength — the point at which the pole will no longer sustain the applied load.
Ornamental pole — a pole designed with a colour andlor specific shape used to adorn or beautify. Note: The definition of ornamental poles is generally but not specifically limited to streetlight poles,
Sealer — a chemical that penetrates the surface of arid fills voids in concrete.
Note: Silanes and siloxanes are the chemical groups that most commonly provide sealers.
Severe exposure — exposure to a corrosive environment similar to, or more corrosive than, a location beside a roadway where considerable road salt is used and the traffic volume and/or speed is consistent with arterial city streets so that the pole is subject to salt-laden spray.
Spun pole — a pole in which the concrete is distributed and compacted by centrifugal force. Tip load — a transverse bending load applied 600 mm (2 ft) from the top of a pole.
Ultimate torsional load — the maximum torque that the pole can sustain without regard to structural damage or loss of serviceability.
Ultimate transverse bending load — the maximum load that the pole can sustain without regard to structural damage o loss of serviceability.CSA A14-07 pdf free download.
