1 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 1.2. 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 minus 29°C (minus 20°F) to 52°C (125°F).

1.2 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 item (b) or formulated in accordance with the Standard Specification for Ethanol Fuel Blends for Flexible-Fuel Automotive Spark-Ignition Engines, ASTM D5798.
