Cylinders, Spheres, and Tubes for the Transportation of Dangerous Goods
Product Details
Preface
This is the fourth edition of CSA Standard B339, Cylinders, Spheres, and Tubes for the Transportation of Dangerous Goods. It supersedes the previous editions published in 1996, 1988, and 1983.
This Standard is one of a series of Standards prepared for use in conjunction with the Transportation of Dangerous Goods Regulations, which adopt this Standard by reference. Since the regulations may adopt this Standard with certain exceptions or additional requirements, they should be consulted to determine where they differ from the requirements of this Standard.
It should be noted that the amended, clear-language version of the Transportation of Dangerous Goods Regulations that reference CAN/CSA-B339-96 came into effect on 15 August 2002. The CSA 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 US Code of Federal Regulations. This edition of CSA Standard B339 incorporates numerous amendments and refinements to the previous edition, while retaining the same basic format used in the previous edition.
The CSA Technical Committee on Cylinders, Spheres, and Tubes for the Transportation of Dangerous Goods is made up of members having responsibility and expertise as manufacturers or users or in related areas that include testing and inspection of containers and materials, material production, and regulatory interests. The Committee is confident that this Standard, developed by consensus, is practical, current with respect to technology and industry practices, useful, and acceptable to all interested parties. This Standard is written in SI (metric) units, except for the cylinder marking requirements, where the service pressure and, where applicable (eg, Specification TC-39M), the test pressure are expressed in bar. However, 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 (International Organization for Standardization) 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 identify formally that the container specification is metricated.
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. It will be submitted to the Standards Council of Canada for approval as a National Standard of Canada.
Scope
1.1 General
This Standard covers requirements for the manufacturing, inspection, testing, marking, requalification, reheat treatment, repair, and rebuilding of cylinders, spheres, and tubes (containers) for the transportation of dangerous goods. In addition, it includes the requirements for the qualification of new designs and registration requirements.
1.2 Designations and Descriptions of Containers
1.2.1
This Standard covers the general requirements for containers (see Clause 4) and specific requirements, as specifications (see Clauses 5 to 23 inclusive), for the manufacture of each type of container. The general requirements are applicable to all containers, unless otherwise stated, or are not relevant in the individual specifications.
1.2.2
The specification designations and descriptions of containers covered in this Standard are listed in Tables 1.1, 1.2, 1.3,1.4, 1.5, and 1.6.
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.
