UL 2583 BULLETIN

Abstract

These requirements cover mechanical type accessories that are typically intended for attachment to storage tanks or connecting pipe in commercial (public) or private (fleet) automotive fueling station applications, and are designed to provide automatic safety or operational functions. <br>These products may be used with underground or aboveground tank systems and with liquid and/or vapor phases of the fuels covered by each Part of this Outline as identified below: <br>Part I Vapor Control Products &#8211; Functional devices and accessories intended for connection to tank top openings (directly on fittings or indirectly on pipe) and perform safety or operational functions, such as emergency vents, normal vents, adapters and caps. <br>Part II Liquid Control Products (reserved for future use) &#8211; Liquid control products such as overfill containment devices, overfill prevention devices, and flow restrictors. <br>Part III Structural and Containment Products (reserved for future use) &#8211; Metallic components such as access devices, manways, supports, and dikes. <br>Part IV Corrosion Protection Products (reserved for future use) &#8211; Nonmetallic components such as tank anchors, dielectric bushings, anode packs, coatings and resins. <br>Part V Miscellaneous Products (reserved for future use) &#8211; Miscellaneous products such as lift lugs, striker plates and monitor well caps. <br>These products are intended for use with storage tanks or fueling systems containing automotive fuels under the expected use conditions and exposures that have similar chemical, physical and material compatibility properties as represented in these requirements. The use fuels are intended to be formulated in accordance with 40 CFR Part 80 "Regulation of Fuels and Fuel Additives" and meet the following ASTM Fuel Specifications and blend limitations: <br>a) ASTM D975, Standard Specification for Diesel Fuel Oils, with biodiesel blends up to a maximum of 5 percent (B5); <br>b) ASTM D7467, Standard Specification for Low Blend Biodiesel, with biodiesel blends between 6 to 20 percent (B6 to B20); <br>c) ASTM D4814Standard Specification for Automotive Spark-Ignition Engine Fuel, gasoline or oxygenated gasoline, with limited ethanol blends up to a maximum of 10 percent (E10); <br>d) ASTM D5798, Standard Specification for Fuel Ethanol (Ed75 &#8211; Ed85) for Automotive Spark- Ignition Engines, high blend ethanol, with gasoline/ethanol mixtures in the nominal E85 range (E70 &#8211; E90); and <br>e) Mid Range Ethanol Blends (E11 to E69) using variable mixtures of ASTM D4814, Low Blend Ethanol and ASTM D5798, High Blend Ethanol. <br>Products covered by this Outline are intended to be installed and used in accordance with one or more of the following: <br>a) NFPA 30, Flammable and Combustible Liquids Code; <br>b) NFPA 30A, Code for Motor Fuel Dispensing Facilities and Garages; <br>c) NFPA 1, Uniform Fire Code; <br>d) International Fire Code published by the International Fire Council; or <br>e) Other Applicable Federal and State regulations for the specific product or application it is being utilized in. <br>These products are factory manufactured and intended for in-shop or on-site assembly, inspection and testing for the specified application and use conditions by qualified persons in accordance with the manufacturer's instructions and local requirements. <br>These products are intended to be periodically inspected and maintained for continued service, or taken out of service if necessary, by qualified persons in accordance with industry recommended practices and/or the manufacturer's instructions. <br>These products have not been evaluated for use after natural disasters, fires or exposures to chemicals not representative of the test liquids/vapors or excessive physical damage beyond the expected assembly, installation and uses as identified in these requirements. <br>These products have not been evaluated for special applications where exposed to heavy or continuous physical abuses, excessive mechanical stresses; or environments that operate outside of the expected atmospheric conditions and ambient use temperature range. <br>These requirements may optionally be evaluated to EPA 40 CFR Part 63 Subpart CCCCCC, CARB (CP-201) or other air quality regulations at the request of the manufacturer. <br>These requirements do not cover flame arrester features or evaluations, which are found in the Standard for Flame Arresters, UL 525.
