Meters for Gasoline and Gasoline/Ethanol Blends with Nominal Ethanol Concentrations Up to 85 Percent (E0 – E85)
Scope 1.1 These requirements cover positive displacement liquid meters for use with motor fuels. Motor fuels, as defined by these requirements, include one or more of the fuels described in 1.3. 1.2 Meters for gasoline/ethanol blends with nominal ethanol concentrations up to 85 % (E0 – E85) shall be constructed to comply with the following: a) The requirements defined in the Standard for Meters for Flammable and Combustible Liquids and LP-Gas, UL/ULC 25; and b) The requirements in this Standard. 1.3 Meters covered by these requirements are intended for use with one or more of the following as applicable: a) Gasoline formulated in accordance with the Standard Specification for Automotive Spark-Ignition Fuel, ASTM D4814; b) Gasoline/ethanol blends with nominal ethanol concentrations up to 25 % ethanol (E25), consisting of gasoline formulated in accordance with the Standard Specification for Automotive Spark-Ignition Fuel, ASTM D4814, when blended with denatured fuel ethanol formulated to be consistent with the Standard Specification for Denatured Fuel Ethanol for Blending With Gasolines For Use as Automotive Spark Ignition Engine Fuel, ASTM D4806; or c) Gasoline/ethanol blends with nominal ethanol concentrations above 25 % formulated in accordance with the Standard Specification in (b) above or formulated in accordance with the Standard Specification for Ethanol Fuel Blends for Flexible-Fuel Automotive Spark Ignition Engines, ASTM D5798. 1.4 Products covered by this Standard are intended to be installed and used in accordance with the applicable Codes and Regulations as determined by the Authority Having Jurisdiction (AHJ), such as, but not limited to: a) In the United States: 1) Flammable and Combustible Liquids Code, NFPA 30; 2) Code for Motor Fuel Dispensing Facilities and Repair Garages, NFPA 30A; b) In Canada: 1) The National Fire Code of Canada; 2) Provincial or other Regulations. 1.5 These requirements do not cover: a) Meters for use with fuels other than as described in 1.3; b) Velocity meters, head meters, or area meters; c) Meters for use in centralized fuel oil distribution systems; and d) Meter components incorporating electrical circuits except those meeting intrinsically safe or explosion standards. 1.6 Determinations of the suitability of registers, counters, or computers used or provided with these meters, or the accuracy of measurement resulting from or required in actual application are not within the scope of these requirements. 1.7 Products intended to be rated for use with gasoline or gasoline/ethanol blends with nominal ethanol concentrations: a) Up to 25 % (E0 – E25) shall be evaluated using the CE25a test fluid as the only applicable test fluid; b) Up to 40 % (E0 – E40) shall be evaluated using both the CE25a and CE40a test fluid, or; c) Up to 85 % shall be evaluated using both the CE25a and the CE85a test fluids. 1.8 For requirements for meters for biodiesel fuel, diesel/biodiesel blends with nominal biodiesel concentrations up to 20 % (B20), refer to the Standard for Meters for Diesel Fuel, Biodiesel Fuel, Diesel/Biodiesel Blends with Nominal Biodiesel Concentrations up to 20 Percent (B20), Kerosene, and Fuel Oil, UL/ULC 25B for additional requirements.
