UL 1369:2018 Standard for Aboveground Piping for Flammable and Combustible Liquids.
1.1 These requirements cover primary, secondary, and coaxial types of aboveground pipes intended for transfer and containment of specific flammable and combustible liquids and fuels or fuel components (and vapors thereof) identified in this Standard, at their manufacturing, processing and distribution facilities, commercial (public) or fleet (private) motor vehicle fueling stations or similar fuel dispensing applications, and piping systems for fuel supply of generators, burners or similar equipment.
1.2 These pipes may be flexible or rigid types constructed with metallic, nonmetallic, or composite
materials in single continuous or multiple joined lengths with integral end fittings in nominal sizes from
12.7 mm to 152.4 mm (0.5 in to 6.0 in) diameters, and are typically intended for use in the following
a) General aboveground use either directly on or suspended above the ground, such as piping between tanks and dispensers or within buildings, such as fuel supply lines to rooftop
generators or basement boilers, which may include short lengths routed in below grade
containment sumps and underground chase pipe where accessible, but not where directly buried; or
b) Special aboveground uses that requires an additional evaluation for a specific purpose, such as marinas, and where specific liquids or extreme environments are not represented by the
general test liquids and expected exposures conditions.
1.3 These pipes are intended for commercially available fuels and fuel components, and similar flammable and combustible liquids under the expected use conditions, and exposures that have similar chemical, physical and material compatibility properties as represented in these requirements.
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:
In the United States:
a) Standard for the Installation of Stationary Pumps for Fire Protection, NFPA 20;
b) Flammable and Combustible Liquids Code, NFPA 30;
C) Code for Motor Fuel Dispensing Facilities and Garages, NFPA 30A;
d) Standard for the Installation of Oil-Burning Equipment, NFPA 31;
e) Standard for the Installation and Use of Stationary Combustion Engines and Gas Turbines,
f) Standard for Aircraft Fuel Servicing, NFPA 407;
g) Uniform Fire Code, NFPA 1;
h) International Fire Code published by the International Fire Council.UL 1369 pdf download.
