This Standard sets forth minimum requirements for hose and hose assemblies, including vapour recovery hose and assemblies, for use on dispensing devices for flammable and combustible liquids. For the purpose of this Standard flammable and combustible liquids mean gasoline, fuel oil, kerosene and diesel fuel, including gasoline with small amounts of additives such as detergents, solvents for detergents and anti-icing chemicals; diesel with up to 5% biodiesel and gasoline with up to 15% ethanol or methyl tertiary butyl ether (MTBE).

This Standard does not cover hose or hose assemblies intended for use in confined areas, or as a component in automotive vehicles and/or in motorized or mechanical equipment, excluding dispensing devices.

 
This Standard sets forth minimum requirements for hose and hose assemblies used on dispensing devices for fuels not covered in Clause 1.1 when found by investigation to have the required resistance to these fuels.

 
This Standard also sets forth minimum requirements for hose and hose assemblies in sizes up to and including 40 mm.

 
Hose for conveying liquid fuel is intended for use at a maximum working pressure of 350 kPa. Hose for conveying vapours of fuel is intended for use at a maximum working pressure of 3.5 kPa, including slight negative pressures from vapour assist systems.

 
This Standard sets forth minimum requirements for hose and hose assemblies for use at temperatures down to -40 °C or -54 °C up to +50 °C.

 
Requirements for the installation and use of equipment handling flammable and combustible liquids may be included in the National Fire Code of Canada and the regulations of the authority having jurisdiction.
