10.1 Metallic materials
10.1.1.1 A metallic part in contact with the fuels anticipated by these requirements shall be resistant to the action of the fuel If degradation of the material will result in leakage of the fuel or It It will impair the function of the device, See the Long Term Exposure Test, Section, 27,
10.1.1.2 The exposed surfaces of metallic parts shall be resistant to atmospheric corrosion if this corrosion will lead to leakage of the fluid or if it will impair the function of the device, The material shall comply with the requirements in Atmospheric corrosion, 10.1.2.
10.1.1.3 Metallic parts in contact with the fuels anticipated by these requirements shall not be constwcted of lead, or materials that are substantially lead In addition, no coatings or platings containing lead shall be used, such as terne-plated steel.
10.1.1.4 With reference to the above requirements, metallic parts include metallic materials used to form fluid confining parts as well as metallic coatings or plating that may be applied to a base material.
10.1.2 Atmospheric corrosion
10.1.2.1 Metallic materials used for fluid confining parts shall be resistant to atmospheric corrosion.
Standard pipe and fittings conforming to the Standard for Welded and Seamless Wrought Steel Pipe.
ASME B36. I OM are acceptable when uncoated.
10.1.2.2 A protective coating shall provide resistance against atmospheric corrosion to a degree not less than that provided by the protective coatings specified in 10.1.2.3.
10.1.2,3 Cadmium plating shall not be less than 0.0003 inch (0.008 mm) thick, and zinc plating shall not be less than 0.0005 inch (0.013 mm) thick, except on parts where threads constitute the major portion of the area In which case the cadmium or zinc plating shall not be less than 0,00015 Inch (00038 mm) thick. Metallic parts are considered to comply with 10.1.2.1 when they are protected against atmospheric corrosion by:
a) Hot dipped, mill galvanized sheet steel complying with the coating designation G90 in Table I of the Specification for Sheet Steel, Zinc Coated (Galvanized) or Zinc-Iron-Alloy Coated
(Galvannealed) by the Hot Dip Process, ASTM A653A653M; or
b) Coatings which have been determined to be equivalent to G90 under the requirements of the Standard for Organic Coatings for Steel Enclosures for Outdoor Use Electrical Equipment, UL 1332.
10.1.2.4 A metallic material other than as described in 10.1.2.1 — 10.1.2.3 shall be painted or protected in a manner that has been determined to be equivalent.
10.2 Nonmetallic materials
10.2.1.1 A nonmetallic part in contact with motor fuel shall be resistant to the action of the fuel if degradation of the material will result in leakage of the fuel, or if it will impair the function of the device. Gaskets and seals are tested in accordance with 10.2.1.2 — 10.2.3.2. Hose materials are tested in accordance with the following:
a) Tensile Strength and Elongation. Section 22:
b) Accelerated Air Oven Aging Test, Section 23; C) Ozone Exposwe, Section 24:
d) Immersion Tests, Section 26.
10.2.1.2 Gaskets or seals shall be designated as dynam.c andloc static seals. See 3.4 and 3.5 respectively. If the type of seal cannot be determined, then the material shall be treated as both a static and a dynamic seal.
10.2.1.3 Gaskets and seals shall comply with the requirements as outlined in Nonmetallic materials — material level, 10.2.2; and Nonmetallic materials — system level. 10.2.3.
10.2.1.4 Nonmetallic materials in contact with the fuels anticipated by these requirements siiall not be constructed of the following:
a) Polysultide rubber:
b) Ethylene propylene deene monomer (EPDM) rubber;
C) Methyl. Methacrylate:
d) Polyvinyl Chloride (PVC):
e) Nylon 66: or
