This Standard sets forth the minimum requirements for the construction and performance of overfill protection devices for installation in aboveground and underground flammable liquid and combustible liquid storage tanks.
For the purposes of this Standard, flammable liquids and combustible liquids include 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 (B5) and gasoline with up to 15% ethanol (E15) in accordance with, but not limited to, the following documents:
A CAN/CGSB 3.18, Diesel Fuel for Locomotive - Type Medium - Speed Diesel Engines
B CAN/CGSB 3.2, Heating Fuel Oil
C CAN/CGSB 3.3, Kerosene
D CAN/CGSB 3.517, Automotive (On-road) Diesel Fuel
E CAN/CGSB 3.520, Automotive Low-Sulphur Diesel Fuel Containing Low Levels of Biodiesel Esters (B1-B5)
G CAN/CGSB 3.6, Regular Sulphur Diesel Fuel

The overfill protection devices shall be designated as Class I or II in accordance with the liquids they are intended to contain, as listed below:
A Class I devices shall be suitable for use with flammable liquids and combustible liquids, described in Clause 1.1.1; and
B Class II devices shall be proved suitable for use with the specific liquid(s) for which the device is intended, by additional testing in accordance with Subsection 6.4, Immersion Test, using the specific liquid(s).
NOTE: Overfill protection devices with materials made with exposed zinc or brass in the wetted area should not be used with jet fuels. Zinc or brass materials used for this application that are nickel plated in accordance with UL 87A, Outline for Power-Operated Dispensing Devices for Gasoline and Gasoline/Ethanol Blends with Nominal Concentrations Up to 85% (E0-E85), are considered acceptable.
