6 Base 6.1 A base shall be made of ordinary cast iron not less than 1 /4 inch (6.4 mm) thick or commercial grade steel not less than 0.093 inch (2.36 mm) thick. Exception: Other materials or constructions may be used if determined to provide equivalent strength. 6.2 A base shall be provided with bolt holes that will accommodate bolts not less than 1 /2 inch (1 2.7 mm) in diameter for anchoring the dispenser. At least two holes shall be provided if the dispenser is not more than 6 feet (1 .8 m) tall and at least four holes if the dispenser is more than 6 feet tall. If two holes are provided, they shall be located on opposite sides of the base and at least 1 3 inches (330 mm) apart. If more than two holes are provided, they shall be located approximately symmetrically on a bolt circle having a diameter of not less than 1 3 inches. The bolt holes shall be accessible, such as by being located in the base at the sides of the dispenser provided with doors or removable panels. Exception: These requirements do not apply to a farm or retail type dispenser of a specific design that includes other provision for anchoring the dispenser. 7 Pedestal 7.1 A pedestal shall be made of cast iron or sheet steel, or of a framework consisting of angle iron, wrought-iron, or steel pipe, or a construction determined to be equivalent. 7.2 Piping carrying liquid shall not serve as a part of the pedestal. 7.3 Provisions shall be made, such as bolting or welding, to prevent loosening of joints in the pedestal.
