UL 1102:1999 pdf download Nonintegral Marine FuelTanks
1 Scope
1.1 These requirements cover nonintegral, vented gasoline fuel tanks designed and constructed inaccordance with theUnited States Coast Guard Safety Standard for Gasoline Fuel Systems, Code ofFederal Regulations, Title 33, Chapter 1, Part 183, Subpart J-1990 and nonintegral diesel fuel tanks.
1.2 The fuel tanks covered by these requirements are intended for fixed installation with deck fill provisionand for permanent installation in accordance with the applicable installation requirements of U.S. CoastGuard; the applicable requirements of the Fire Protection Standard for Pleasure and Commercial MotorCraft (National Fire Codes, vol. 6), NFPA 302-1994; and/or the requirements of the American Boat 8Yacht Council, Inc.
1.3 These requirements do not cover portable marine fuel tanks or tanks integral with any boat structure.
1.4 A product that contains features, characteristics, components, materials, or systems new or differentfrom those covered by the requirements in this standard, and that involves a risk of fire, electric shock, orinjury to persons shall be evaluated using the appropriate additional component and end-productrequirements as determined necessary to maintain the acceptable level of safety as originally anticipatedby the intent of this standard. A product whose features, characteristics, components, materials, orsystems conflict with specific requirements or provisions of this standard cannot be judged to comply withthis standard. Where considered appropriate, revision of requirements shall be proposed and adopted inconformance with the methods employed for development, revision, and implementation of this standard.
2 General
2.1 Components
2.1.1 Except as indicated in 2.1.2, a component of a product covered by this standard shall comply withthe requirements for that component.
2.1.2 A component need not comply with a specific requirement that
a) lnvolves a feature or characteristic not needed in the application of the component in theproduct covered by this standard, or
b) Is superseded by a requirement in this standard.
2.1.3 A component shall be used in accordance with its recognized rating established for the intendedconditions of use.
2.1.4 Specific components are recognized as being incomplete in construction features or restricted inperformance capabilities. Such components are intended for use only under limited conditions, such ascertain temperatures not exceeding specified limits, and shall be used only under those specific conditionsfor which they have been recognized.
2.2 Units of Measurement
2.2.1 lf a value for measurement is followed by a value in other units in parentheses, the second valuemay be only approximate. The first stated value is the requirement.
CONSTRUCTION
3 General
3.1 All exterior edges, projections, and corners shall be smooth and rounded.
3.2 All joints and seams shall be equal to or stronger than the material being joined and shall neitherprovide nor create crevices in which water may collect.
3.3 The material bend radius of rectangular and specially shaped tanks and of baffle flanges and the likeshall be not smaller than the minimum bend radius specified by the material manufacturer for theparticular alloy and material thickness.
3.4 There shall be no openings in the bottom, sides or ends of a fuel tank other than as specified in 7.3.Any opening into the fuel tank, for example fill pipe feed pipe, vent connections, shall be at or above thetopmost surface of the tank
3.5 A fuel tank tested for compliance with this Standard shall be tested as a complete assembly, includingall components necessary for its intended function and installation.
3.6 Fuel tanks shall withstand a pressure not less than 1-1/2 times the test pressure marked on the tanklabel. The test pressure marked on the label shal! be not less than the maximum hydrostatic head to whichthe tank will be subjected in intended service, but not less than 3 pounds per square inch gauge (psig(20.7 kPa). See Pressure Leakage Test, Section 17.
4 Materials
4.1 All metallic parts of the tank or combinations of metallic parts shall have corrosion resistanceequivalent to the materials and minimum thicknesses listed in Table 4.1. Tanks fabricated of the materialsand material thicknesses listed in Table 4.1 will be considered acceptable without corrosion testing.Metallic materials not listed in Table 4.1 may be considered acceptable if a corrosion evaluation showsthe material or materials to be equivalent to or better than any of the materials listed in Table 4.1. A partin contact with the fluid intended to be handled by the fuel tank shall be resistant to the action of suchfluid. Metallic combinations shall be resistant to galvanic corrosion.
