1 Scope
1.1 These requirements cover positive displacement liquid meters for:

a) Flammable and combustible liquids of the type and size commonly used in the assembly of motor fuel dispensing devices and
b) Liquefied petroleum gas (LP-Gas) of the type and size commonly used in the assembly of motor fuel dispensing devices and tank trucks.

1.2 “Flammable and Combustible Liquids,” as used herein, means gasoline, gasoline/alcohol blends up to 15% Ethanol or 15% Methanol, diesel fuel, fuel oil, lubricating oil, kerosene, and the vapors of these fuels. Other petroleum products are not prohibited from being used in the meter when the materials comply with the requirements in Materials, Section 5, and when the meter is evaluated using the additional liquids. Petroleum products shall be handled at pressures not exceeding 50 pounds per square inch gauge (psig) (345 kPa) and at temperatures within the range of minus 29&degC (20&degF) – 52&degC (125&degF).
1.3 Flammable and combustible liquid meters covered by this standard are for use in accordance with the National Fire Protection Association’s Flammable and Combustible Liquids Code, NFPA 30, and the Code for Motor Fuel Dispensing Facilities and Repair Garages, NFPA 30A.
1.4 LP-Gas meters covered by this standard are for use in nonrefrigerated systems in accordance with the National Fire Protection Association’s Liquefied Petroleum Gas Code, NFPA 58.
1.5 These requirements do not cover:

a) Meters for use with liquefied petroleum gas in the gaseous phase;
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.
