B109-14 - Natural gas for vehicles installation code

Preface

This is the second edition of CSA B109, Natural gas for vehicles installation code. It supersedes the previous edition published in 2001 under the title Natural gas for vehicles installation code - Part 1 Compressed natural gas.

This Code consists of the following:

a) CSA B109, Part 1 - Compressed natural gas; and

b) CSA B109, Part 2 - Liquefied natural gas.

This Code is made possible by a financial contribution from Natural Resources Canada.

B109-14, Part 1 - Compressed natural gas

Scope

1.1
This Code applies to the installation, inspection, repair, and maintenance of the fuel storage and delivery system installed in powered industrial truck applications and on road vehicles for use with compressed natural gas (CNG) or the compressed natural gas portions of an LNG fuel system. This includes fuel systems on self-propelled vehicles for the provision of motive power.

This does not apply to vehicles (including their containers) tested and qualified under the Canadian Motor Vehicle Safety Regulations.

1.2
This Code does not apply to

a) stationary engines;

b) mobile equipment using natural gas as a fuel for other than propulsion;

c) LNG fuel storage system*;

d) electronic components of a fuel management system;

e) storage or utilization of natural gas on boats or trains;

f) all terrain vehicles;

g) motorcycles; and

h) vehicles (including their containers) qualified under the Canadian Motor Vehicle Safety Regulations.

* Part 2 of this Code covers the liquid portion of LNG Fuel Systems.

1.3
All references to "psi" throughout this Code are to be considered gauge pressures, unless otherwise specified.

1.4
This Code contains SI (Metric) corresponding to the English units, the purpose being to allow the Code to be used in SI (Metric) units. American National Standard for Metric Practice, IEEE/ASTM SI 10 or ISO 80000-1, Quantities and units - Part 1: General, is used as a guide in making metric conversion from English units. If a value for a measurement and a corresponding value in other units are stated, the first stated value is to be regarded as the requirement. The given corresponding value may be approximate. If a value for a measurement and a corresponding value in other units are both specified as a quoted marking requirement, the first stated unit, or both, are to be provided.

Where the word "gallon" is used in this Code, it indicates a U.S. Gallon equivalent to 3.785 liters water capacity.

1.5
In this Code, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Code; "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 Code.

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.

B109-14, Part 2 - Liquefied natural gas

Scope

1.1
This Code applies to the installation, inspection, repair, and maintenance of the fuel storage and delivery system installed in powered industrial truck applications and on road vehicles for use with liquefied natural gas (LNG). This includes fuel systems on self-propelled vehicles for the provision of motive power.

This Part does not apply to the compressed natural gas portions of an LNG fuel system.

1.2
This Code does not apply to

a) stationary engines;

b) mobile equipment using natural gas as a fuel for other than propulsion;

c) electronic components of a fuel management system;

d) storage or utilization of natural gas on marine vessels or rail vehicles or transportation by tanker truck;

e) off road vehicles, including all-terrain vehicles; and

f) motorcycles;

* Part 1 of this Code covers the gaseous natural gas portions of an LNG fuel system downstream of the vapourizer (heat exchanger).

1.3
All references to "psi" throughout this Code are to be considered gauge pressures, unless otherwise specified.

1.4
This Code contains SI (Metric) corresponding to the English units, the purpose being to allow the Code to be used in SI (Metric) units. If a value for a measurement and a corresponding value in other units are stated, the first stated value is to be regarded as the requirement. The given corresponding value may be approximate. If a value for a measurement and a corresponding value in other units are both specified as a quoted marking requirement, the first stated unit, or both, are to be provided.

Note: IEEE/ASTM SI 10 or ISO 80000-1 are used as a guide in making metric conversion from yard/pound quantities. Where the word "gallon" is used in this Code, it indicates a U.S. Gallon equivalent to 3.785 litres water capacity.

1.5
In this Code, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Code; "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 Code.

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.
