scope:

This Standard details the requirements for the selection and use, handling, filling, and unloading of highway tanks and TC portable tanks used as means of containment for the transportation of dangerous goods of Class 2.

This Standard sets out certain minimum requirements for the selection of the appropriate means of containment for the transportation of dangerous goods. This Standard does not, however, prescribe selection of the materials of construction of the means of containment to ensure chemical compatibility with the dangerous goods. Consequently, it is essential to exercise competent technical and engineering judgment in conjunction with this Standard.

Where any requirement of this Standard differs from the Transportation of Dangerous Goods (TDG) Regulations, the requirements of the TDG Regulations apply. Where there is an inconsistency between this Standard and a referenced publication other than the TDG Act or Regulations, the requirements of this Standard prevail. Application of a referenced publication should be made only with careful consideration of this Standard's reference to that particular publication.

This Standard does not apply to tubes for the transportation of gases. Requirements for these tubes are provided in CSA B340.

This Standard does not apply to TC 106, TC 110, CTC 106, CTC 110, DOT 106, DOT 110, ICC 106, and ICC 110 tanks. Requirements for these tanks are provided in TP 14877. (See Clause 4.3.)

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. The values given in parentheses are for information and comparison only. Note: Units for pressure refer to gauge pressure unless otherwise noted.
