The users of this Standard should note that it is a recommendatory document only and does not have the force of law except where it has been officially adopted by a Canadian jurisdiction.

Users should also note that adoption does not necessarily mean that the Standard has been adopted unchanged. For example, a jurisdiction may decide to make an informative annex normative. In addition, owners and users of cylinders designed to the requirements of Part 2 should note that the safe operation of such cylinders requires, first, compliance with the service conditions specified by the manufacturer, and second, use of the cylinders only during the service life specified by the manufacturer.

Each cylinder is marked with an expiry date, and owners and users are responsible for ensuring that a cylinder is not used after that date. The Technical Committee intends to meet periodically to review this Standard and, if necessary, to revise it to meet changing conditions and maintain uniformity of practice throughout Canada. It is the responsibility of the user of this standard to be aware that applicable local regulations can take precedence over the requirements of that Code. Notes: 1 It is possible that the size limitations specified in provincial or territorial statutes or regulations will differ from those specified in Part 1 of this Standard.

The applicable regulatory authority should be consulted. 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 nonmandatory to define their application. The values given in parentheses are for information only. Nominal pipe sizes are expressed in non-dimensional terms. The use of gas cylinders is governed by the Act. Users and manufacturers should note the need to apply to the applicable regulatory authorities for approval of gas cylinders. Scope 1. Cylinders may be of any material steel, aluminum, or non-metallic and constructed in accordance with any design or method of manufacture suitable for the specified service conditions.

The service life of a cylinder is defined by the manufacturer and can vary with different applications.

The maximum service life of Type 2, Type 3, and Type 4 cylinders is 20 years. For all cylinders, a safe life design principle is used. For metal and metal-lined cylinders, the cylinder life is based on the rate of fatigue crack growth. Ultrasonic or equivalent inspection of each cylinder or liner is necessary to ensure that there are no flaws that exceed the maximum allowable size determined by fracture mechanics.

This approach optimizes the design and manufacture of lightweight cylinders for natural gas vehicle service. For all-composite cylinders with non-metallic non-load-bearing liners, safe life is ensured by appropriate design methods, design qualification testing, and manufacturing controls.
