Scope

1.1
This Standard specifies requirements for the design, construction, initial inspection and testing, marking, periodic inspection and testing, and repair of UN pressure receptacles and multiple-element gas containers (MEGCs) for the transport of dangerous goods. Annex A specifies the regulatory requirements for the conformity assessment system and registration requirements for manufacturers and inspection bodies. Annex B specifies the regulatory requirements for the conformity assessment system and registration requirements for periodic inspection and test bodies and for repair facilities. Annex C specifies the design approval process for multiple-element gas containers. Tables 1 to 6 provide information on the UN pressure receptacles covered by this Standard.
Note: It should be noted that compliance with the provisions of the Transportation of Dangerous Goods Act and the Regulations thereto may call for additional requirements due to particular characteristics or properties of individual dangerous goods.

1.2
In CSA Standards, "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; "may" is used to express an option or that which is permissible within the limits of the standard; and "can" is used to express possibility or capability. 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.
