CAN/CSA-B339 sets out the requirements for the manufacturing, inspection, testing, marking, requalification, reheat treatment, repair, and rebuilding of cylinders, spheres, and tubes (containers) for the transportation of dangerous goods. It also sets out the requirements for new design qualification and registration.
Subsection 5.10(2) of the TDG Regulations specifies that cylinders and tubes for transport of dangerous goods in Class 2, manufactured starting January 1, 1993, must be manufactured in accordance with CAN/CSA-B339. Cylinders and tubes manufactured before January 1, 1993 must meet the requirements specified in paragraphs 5.10(2)(b) or 5.10(2)(c) of the TDG Regulations.
A copy of this standard can be obtained from the Canadian Standards Association (CSA).
In many cases a new edition or an amendment to a standard may have been published but not (yet) prescribed by the TDG Regulations. Nonetheless, the version of a standard prescribed by the regulations in paragraph 1.3.1 is the one legally in force
