Selection and use of cylinders, spheres, tubes, and other containers for the transportation of dangerous goods, Class 2
This is the eighth edition of CSA B340, Selection and use of cylinders, spheres, tubes, and other containers for the transportation of dangerous goods, Class 2. It supersedes the previous editions published in 2018, 2014, 2008, 2002, 1997, 1988, and 1986. This Standard is one of a series of Standards adopted by reference by the Transportation of Dangerous Goods Regulations. Because the Regulations might adopt this Standard with certain exceptions or additional requirements, they should be consulted to determine where they differ from the requirements of this Standard. Notwithstanding the provisions of this Standard, compliance with the provisions of the Transportation of Dangerous Goods Act and the regulations thereto might call for additional requirements due to particular characteristics or properties of individual dangerous goods. Any requirements of the Transportation of Dangerous Goods Regulations regarding the handling, the offering for transport, and the transportation of dangerous goods in cylinders, spheres, and tubes are to be fully complied with. The Technical Committee on Cylinders, Spheres, and Tubes for the Transportation of Dangerous Goods, which is responsible for this Standard, has maintained close links with Transport Canada to ensure compatibility of the new edition of this Standard with the amended Transportation of Dangerous Goods Regulations. The Committee has also reviewed and made extensive use of Compressed Gas Association publications and the U.S. Code of Federal Regulations. The following are the major changes to this edition
This Standard was prepared by the Technical Committee on Cylinders, Spheres, and Tubes for the Transportation of Dangerous Goods, under the jurisdiction of the Strategic Steering Committee on Public Safety, and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group
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.
This Standard covers requirements for the handling and filling of cylinders, spheres, tubes, and other containers for the transportation of dangerous goods, Class 2.
The following containers are not covered in this Standard
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.
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.
