5.1.1 General
5.1.1.1 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 if it will impair the function of the device. See the Long Term Exposure Test. Section .
5.1.1.2 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. 5.1.2.2.
5.1.1.3 Metallic parts in contact with the fuels anticipated by these requirements shall not be constructed of lead, or materials that are substantially lead. In addition, no coatings or p4atings containing lead shall be used, such as terne-plated steel.
5.1.1.4 With reference to the above requirements, metallic parts include metallic matenals used to form fluid confining parts as weit as metallic coatings or plating that may be applied to a base material.
5.1.2 Atmospheric corrosion
5.1.2.1 Metallic matenals used for fluid confining parts shall be resistant to atmospheric corrosion. In addition, metallic materials that are required to operate to address safety (e g. thermal links on shear valves) shall be resistant to atmospheric corrosion. Ferrous materials of the thickness specified in the following items are acceptable for the preceding when uncoated
a) A casting having a wall thickness of not less than 1/4 inch (6.4 mm) if shown by production test to be tree of leakage:
b) Standard pipe and fittings conforming to the Standard for Welded and Seamless Wrought Steel Pipe. ANSIIASME B36.1OM: and
C) Fabricated sheet steel parts having a minimum wall thickness of 0.093 inch (2.36 mm)
5.1.2.2 A protective coating shall provide resistance against atmospheric corrosion to a degree not less than that provided by the protective coatings specified in 5.1.2.3.
