Draft Scope/Description:

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  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; “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.

1.4  Measurement

This Standard is written in SI units except for the cylinder marking requirements, where the service pressure and, where applicable (e.g., Specification TC-39M), the test pressure are expressed in bar or pounds per square inch gauge (psig). 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, it was decided to use the same unit for marking service pressure in this Standard. When the capital letter “M” has been added to a specification designation, it identifies that the container specification is metricated.
