This standard does not apply to large means of containment that are used exclusively for non-dangerous goods. This standard consists of nine main sets of requirements and one annex. Sections 1 through 3 specify the general scope, normative references and terms and definitions. Section 4 sets out general requirements and defines the applicability of the standard and the precedence of each section. Section 5 outlines the registration requirements applicable to facilities performing manufacture, inspection, maintenance or qualification of ton containers. Section 6 sets out ton container manufacturer and modification requirements. Section 7 sets out the requirements for the periodic qualification and maintenance of ton containers. Section 8 covers the selection and use requirements for ton containers. Section 9 provides allowances for one time low risk movement of non-conforming ton containers. Annex A (normative) sets out, in Schedule 1, the requirements applicable to special provisions 1 to 25, and, in Schedule 2, lists dangerous goods and specifies the special provisions that are applicable to each of the listed dangerous goods. 1.2 Minimum requirements This standard sets out certain minimum requirements regarding the design, manufacture, qualification, testing, selection and use of ton containers. It is essential to exercise competent technical, engineering and safety judgment in conjunction with this standard. 1.3 Additional requirements 1.3.1 Conflict The Transportation of Dangerous Goods Act, 1992 (TDG Act) and the Transportation of Dangerous Goods Regulations (TDG Regulations) may set out additional requirements regarding the design, manufacture, testing, selection and use of containers. Where there is an inconsistency between the requirements of this standard and those of the TDG Act or TDG Regulations, the TDG Act or TDG Regulations prevail to the extent of the inconsistency. It is recommended to read the standard in conjunction with the TDG Regulations. 1.3.2 Safety The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This standard does not purport to address all the safety aspects associated with its use. Anyone using this standard has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use. 1.3.3 Units Quantities and dimensions used in this standard are given in units from the International System of Units (SI units). Imperial equivalents may be shown in brackets, if applicable. 1.3.4 Pressures Pressures of all kinds relating to containers (such as test pressure, internal pressure, pressure-relief device start-to-discharge pressure) are indicated in gauge pressure unless specifically noted otherwise. 1.3.5 Classification Dangerous goods are classified in accordance with Part 2, Classification, of the TDG Regulations and the appropriate shipping names and corresponding particulars (UN number, classification and packing group, as applicable) selected from Schedule 1 of the TDG Regulations.
