Flexible connectors may be metallic, nonmetallic or composite, and have integral end fittings, but are limited to a maximum length of 12 ft in nominal sizes up to 4 in. for use as piping components within fuel -dispensing and/or vapor -recovery systems. Flexible connectors may be used underground (where routed through chase pipe), in enclosed sumps (such as tank, dispenser or transition types), or aboveground. The combinations of containment types, location and liquid ratings are described under TYPES AND RATINGS below. These connectors are intended to be installed and used in accordance with the manufacturer's instructions and one or more of the following codes: ANSI/NFPA 1, "Fire Code" ANSI/NFPA 30, "Flammable and Combustible Liquids Code" ANSI/NFPA 30A, "Code for Motor Fuel Dispensing Facilities and Repair Garages" The "International Fire Code" (published by the ICC) Other codes or federal or state regulations of the Authority Having Jurisdiction These connectors are intended to be field assembled by qualified persons in accordance with the manufacturer's instructions and, for continued leak -tight service, require periodic inspection and maintenance or replacement. TYPES AND RATINGS The following types of flexible connector pipe constructions and ratings are marked on the product and indicated in the individual Listings. Containment Ratings Primary — Single-wall pipe construction intended to contain and convey the intended fuels flowing in a piping system under normal use. Secondary — Single-wall pipe construction intended to surround the primary, contain the fuels under abnormal conditions (such as primary rupture) and provide fluid communication and monitoring capabilities. Coaxial — Double-wall pipe construction consisting of integral primary and secondary pipe with a defined interstitial space that provides fluid communication and monitoring capabilities. Location Ratings Underground — Installed below the earth's surface, but accessible without digging, such as within chase piping. Sump — Installed within an enclosed structure (below, above or at grade) and intended to provide protection and access of components. Aboveground — Installed on or above the earth's surface. Liquid Ratings Automotive Fuels — Only those fuels formulated in accordance with 40CFR80, "Regulation of Fuels and Fuel Additives," and meeting the following ASTM fuel specifications and blend limits: ASTM D975 diesel with or without biodiesel blends up to 5% (85) ASTM D7467 diesel with biodiesel blends between 6% - 20% (B6 - B20) ASTM D4814 gasoline with ethanol blends up to 10% (E10) ASTM D5798 ethanol/gasoline blends in the nominal E85 range (E70 - E90) Mid-range ethanol/gasoline blends of ASTM D4814 and ASTM D5798 http://database.ul.com/cgi-bin/XYV/template/LISEXT/ 1 FRAME/showpage.... 7/22/2013
