CONDITIONS

(h) the cylinder shells are manufactured by the backward extrusion method;

(i) the cylinder bottoms have a minimum thickness not less than two times the minimum design wall thickness when measured within an area bounded by a line representing the points of contact between the cylinder and the floor when the cylinder is in a vertical position;

Explanatory Note

The cylinders have previously been manufactured under a Special Permit No. SP 1897 granted pursuant to the Regulations for the Transportation of Dangerous Commodities by Rail. The applicant had demonstrated that by restricting certain design parameters as well as the types of gases that could be contained, a cylinder of reduced wall thickness could be manufactured with equivalent safety. The present permit authorizes continued manufacture and use of the cylinders under the Transportation of Dangerous Goods Regulations.
