CSA B340:24

1 Scope 1.1 Purpose This Standard covers safety requirements for the selection and use of cylinders, spheres, tubes, and other containers for the transportation of dangerous goods, Class 2. 1.2 Subjects addressed This Standard covers requirements for the handling and filling of cylinders, spheres, tubes, and other containers for the transportation of dangerous goods, Class 2. 1.3 Exclusions The following containers are not covered in this Standard: a) containers of 120 mL or less in water capacity except gas lighters; b) containers of 1 L capacity or less filled to not more than 1150 kPa at 15 °C, or 115 L capacity or less filled to not more than 500 kPa at 15 °C, when the containers are filled with materials that are not dangerous goods to not more than 90% of their capacity at 15 °C, and then filled with a non-flammable, compressed gas; c) containers, including aerosol containers of 820 mL or less water capacity, filled with a non-toxic, non-corrosive solution and gas(es) where the pressure in the containers does not exceed 1200 kPa at 55 °C; d) food, carbonated beverage, soap, and biological material containers; electronic tubes; and audible fire alarm systems; e) fire extinguishers partially filled with gases to not more than 1650 kPa at 21 °C and having a water capacity not exceeding 18 L; f) fuel containers of self-propelled vehicles or machinery; g) pressure containers used as component parts of passenger restraint systems in motor vehicles; h) tires and pressure containers used as component parts of tire inflation systems in motor vehicles; i) water pump system tanks charged with gas; j) balls used for sports; k) chemical ammunition; l) gas identification sets; m) portable tanks; n) non-refillable containers other than TC-39M or DOT-39; o) glass ampoules and vials; p) metal cartridges; q) inside containers other than those listed in Clause 4.9; r) bulk transportation and storage tanks; and s) non-pressured containers except vacuum-insulated containers used for refrigerated liquefied gases 1.4 Terminology In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application. 1.5 Units of measurement The values given in SI units are the units of record for the purposes of this Standard except for the cylinder marking requirements where the service pressure and the test pressure, where applicable (e.g., Specification TC-39M), are expressed in bar. For consistency in the design and test requirements of all containers, MPa and kPa have been retained as units to express service pressure. Considering the use of the bar unit by ISO to mark service and test pressures, the Technical Committee decided to use the same unit for marking service pressure. The capital letter “M” is added to each specification designation to formally identify the container specification is metricated.
