Luminaires and Traffic Signals". Ensure that the combined stress ratio above the
first field joint is greater than the combined stress ratio at the base of the pole.
The design wind speed for all areas of the State shall be 90 mph (145 km/h).
The Director may require various tests including destructive tests at either the
factory or on site prior to acceptance of a support in which case the Department s
representative will supervise the Contractor and/or manufacturer as the appropriate
entity perform the tests on supports selected at random by the Department from the
lot produced for the project. Ensure that any support damaged by the testing is
replaced at no additional cost to the Department.
Ensure that the support identification labels are adhesive labels with silver white
reflective characters on a reflective green background meeting the requirements of
730.18.
Furnish certified luminaire supports according to Supplement 1091
A. Light Poles. Ensure that the deflection of the pole from vertical when placed
under the load of the bracket arm, and a weight of 75 pounds (35 kg) in place of
each luminaire does not exceed an angle of 1 degree 10 minutes when tested in
accordance with Supplement 1025 and that certified copies of the results obtained
from the deflection tests are furnished the Laboratory.
A pole and arm constructed from either aluminum or steel but not a
combination of the two may be furnished.
Ensure that each bracket arm is made from straight or tapered stock round or
ovaliptic in cross section not less in size than 2 inch (50 mm) nominal pipe.
Ensure that the luminaire end of each bracket arm has an outside diameter equal
to 2 inch (50 mm) pipe, is straight for a distance of eight inches (203 mm), with
the longitudinal axis canted not less than 1 degree nor more than 4 degrees above
horizontal.
Ensure that the bracket has an internal raceway with a minimum internal
diameter of 1-3/32 inches (28 mm) free of projections and obstructions, which,
when assembled to the shaft, will permit installation of luminaire supply
conductors without insulation damage and which will not require bending the
conductors to a radius less than 3 inches (75 mm).
Ensure that the pole does not have more than two sections, that the shorter
section of a sectional is at the top and that the shorter section of a sectional pole is
not less than 10 feet (3 m) in length. Ensure that the pole sections are joined by
telescoping the bottom of the upper section over the top of the lower section for a
minimum length of 1 1/2 times the external diameter of the bottom of the upper
section, driving the joint tight, and securing by through bolting with a stainless
steel hex head bolt of a minimum diameter of 5/8 inch (16 mm).
Ensure that a pole section does not have more than one longitudinal,
automatically electrically welded seam and no transverse seams. Ensure that the
longitudinal welded seam is neat and uniform in appearance, that the weld is not
be less than the thickness of the base material and that the bead height does not
exceed 1/16 inch (2 mm). Ensure that the wall thickness is uniform throughout,
