Default Hydrostatic Testing
Aluminum & Steel Cylinders require Hydrostatic testing every 5 years, Fiber Glass Composite Cylinders require testing every 3 years, Carbon Composite cylinders require testing every 5 years. Make sure if you purchase cylinders from the US, that they have a TC (Transport Canada) stamp and number on the cylinder as well as a DOT (Department Of Transport) stamp and number. If your cylinder is newer than 1993 and does not have a TC stamp it cannot be hydrotested in Canada. The best place in Edmonton to get your cylinders Hydro Tested is Atlas Fire & Safety Equipment Ltd.

Cheers
