Documentation Requirements for Cylinders

May 13, 2005

Periodically Aircom Instrumentation is asked to provide additional documentation (ie. Material Test Reports, Pressure test results, etc.) with orders of our Transport Canada approved cylinders. This is neither necessary nor required.

Aircom Instrumentation manufactures cylinders in compliance with CAN/CSA B339 & B340 (Latest revision). As such the ''TC-SU-4508'' stamped on our TC approved cylinders authorizes us to manufacture and offer for sale, cylinders that have undergone stringent testing and prequalification of raw materials. (PMI, flattening tests, etc.)

Our cylinders are 100% inspected by a Transport Canada approved independent inspection agency and results are reported to Transport Canada. The welds of our cylinders are visually inspected twice prior to acceptance. Wall thickness tests and hydro testing of each cylinder to 1.5 times its rated pressure is performed, witnessed and documented. Samples from every lot we manufacture are destructively tested to ensure compliance as well.

A cylinder marked with ''TC-SU-4508'' is a cylinder that has undergone some of the most stringent test requirements on the globe. It is your assurance that dangerous goods contained within, will remain within and can be transported by air, road, rail or vessel with the highest degree of safety.

For further information please consult TDG (Transport of Dangerous Goods Directorate online at:, CAN/CSA B339-02, CAN/CSA B340-02, or by contacting us directly.

We thank you for your patronage and look forward to assisting you with your sample cylinder requirements.

Sincerely, Colin Harcourt, President
