Description / Abstract:
These requirements cover emergency breakaway fittings, swivel
connectors and pipe-connecting fittings of the threadless
compression type. Connectors and fittings covered by these
requirements are intended only for the following services.
A swivel connector is either a hose swivel or joint swivel. The
swivel connector will allow radial movement and shall be
constructed for use with the fluids shown in 1.4.
An emergency breakaway fitting is used between the outlet of the
dispensing device and the hose nozzle valve and separates in the
event that the coupling is subjected to an excessive pull force to
safeguard against abnormally excessive pull force on the hose
assembly and dispenser and prevent loss of liquid. An emergency
breakaway fitting shall be constructed for use with the fluids
shown in 1.4. The fittings shall be of the single-break or
reconnectable type.
Emergency breakaway fittings, swivel connectors, and
pipe-connecting fittings 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 percent 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 percent 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.
Requirements for the installation and use of dispensing
equipment handling the fuels described in 1.4 are included in the
Flammable and Combustible Liquids Code, ANSI/NFPA 30, and the Code
for Motor Fuel Dispensing Facilities and Repair Garages, ANSI/NFPA
30A.
These requirements do not cover devices intended for use with
diesel, biodiesel, diesel/biodiesel blends, kerosene or fuel oil,
which are covered under the Outline of Investigation for Emergency
Breakaway Fittings, Swivel Connectors, and Pipe-Connection Fittings
for Diesel Fuel, Biodiesel Fuel, Diesel/Biodiesel Blends With
Nominal Biodiesel Concentrations Up To 20 Percent (B20), Kerosene,
and Fuel Oil, UL 567B.
These requirements do not cover devices intended for use with
anhydrous ammonia or LP-Gas, which as covered under the Standard
for Emergency Breakaway Fittings, Swivel Connectors, and
Pipe-Connection Fittings for Petroleum Products and LP-Gas, UL
567.
