Definitions

For the purpose of this technical bulletin, the following definitions apply:

- Endplug-fitting installed in the end of a tube that acts as an adapter between the tube and the pressure relief device (PRD), valve, or other fitting installed in the end of the tube.

NOTE-Also commonly known as a bullplug.

- Internal PRD-pressure- and/or temperature-activated device used to prevent the pressure in a tube from rising above a predetermined maximum that is installed within the tube and/or endplug to protect it from accidental damage that can cause the device to activate prematurely.

- Motor vehicle-vehicle, machine, tractor, trailer, semi-trailer, or any combination thereof propelled or drawn by mechanical power and used on the highways in the transportation of passengers or property.

- Tube-seamless compressed gas cylinder.

NOTE-A tube is authorized for transportation only when horizontally mounted on a motor vehicle or in an International Organization for Standardization (ISO) framework or other framework of equivalent structural integrity.

NOTE-Also defined by Transport Canada's (TC) Transportation of Dangerous Goods Regulations as a large means of containment that is cylindrical in shape and capable of withstanding an internal absolute pressure of 12.4 MPa [1].

- Tube bundle-group of tubes and their related attachments such as bulkheads or saddles.

NOTE-This grouping of tubes and related attachments and framework cannot be used independently of the tube trailer or tube module.

- Tube module-assembly, comprised of a tube bundle mounted within a structural frame that is designed to be temporarily mounted on a motor vehicle for transportation.

NOTE-This group of tubes and related attachments and framework forms a stand-alone unit attached to the trailer chassis as a whole, separate and distinct unit. Tube modules are also known as skid containers, ISO skids, ISO containers, or multiple-element gas containers (MEGCs).

- Tube trailer-trailer or semi-trailer motor vehicle designed specifically for the transportation of horizontally mounted tube bundles.
