ANSI/CAN/UL/ULC 842A:2024

Scope 1.1 These requirements cover valves that are intended to be used for the control of fluids and their vapors for the fluids indicated in 1.3. They are of the type commonly used in piping systems and in the assembly of motor fuel dispensing equipment. Valves covered by this standard are for use with flammable fluids which are handled at temperatures normally within the range of –20 °F (–29 °C) to 125 °F (52 °C). 1.2 Valves 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 Valves for Flammable and Combustible Liquids, UL/ULC 842; and b) The requirements in this Standard. 1.3 Valves 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) or formulated in accordance with the Standard Specification in (b) or formulated in accordance with the Standard Specification for Ethanol Fuel Blends for Flexible-Fuel Automotive Spark-Ignition Engines, ASTM D5798. 1.4 These requirements cover valves of the manually operated, pressure operated, or temperature operated types, or combinations of such to the exclusion of types operated wholly or partially by electricity. When they form a part of an assembly which provides for additional functions or service, the requirements are outside the scope of these requirements. 1.5 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; or 2) Provincial or other Regulations. 1.6 These requirements do not cover the following: a) Valves for handling liquids under cryogenic conditions; b) Valves for general refinery service, offshore and pipe line terminals, natural gas processing plants, gas distribution systems, petrochemical processing facilities, or the like; c) Constant-level oil valves and electrically operated valves; d) Relief valves and pressure regulators for liquefied petroleum gas (LP-Gas) service; e) Shutoff, emergency shutoff and check valves for liquefied petroleum gas (LP-Gas) in the liquid phase; f) Manually operated gas valves of the plug and body or rotating disc type which are evaluated under the Standard for Manually Operated Gas Valves for Appliances, Appliance Connector Valves and Hose End Valves, ANSI Z21.15; g) Valves covered by the Standard for Gas Appliance Pressure Regulators, ANSI Z21.18; the Standard for Automatic Valves for Gas Appliances, ANSI Z21.21; or the Standard for Gas Appliance Thermostats, ANSI Z21.23; h) Hose Nozzle Valves for Flammable and Combustible Liquids, UL/ULC 2586; i) Valves covered by the Standard for Manually Operated Metallic Gas Valves for Use in Gas Piping Systems up to 125 PSI (Sizes NPS 1/2 through NPS 2), ANSI/ASME B16.33 and Manually Operated Metallic Gas Valves for Use in Aboveground Piping Systems up to 5 PSI, ASME B16.44; j) Manually operated valves for diesel fuel, biodiesel fuel, diesel/biodiesel blends, kerosene, or fuel oil, which are covered under the Standard for Valves for Diesel Fuel, Biodiesel Fuel, Diesel/Biodiesel Blends with Nominal Biodiesel Concentrations up to 20 Percent (B20), Kerosene, and Fuel Oil, UL/ULC 842B; k) Manually operated valves for LP-Gas, which are covered under the Standard for Valves for Flammable Fluids, UL/ULC 842; l) Hose Nozzle Valves for Diesel Fuel, Biodiesel Fuel, Diesel/Biodiesel Blends with Nominal Biodiesel Concentrations up to 20 Percent (B20), Kerosene, and Fuel Oil, UL/ULC 2586B. 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 fluids; or c) Up to 85 % shall be evaluated using both the CE25a and the CE85a test fluids.
