Footnotes to table XIV:
1.
Table XIV does not apply to castings used in components and accessories covered by sections 14. 15. and 16 in which the NDT requirements are specifically listed for the castings involved.
2. 3.
Pressure' is the design pressure of the system in which the casting is used.
For machinery and pressure vessel castings, the size shown is the inside diameter (or an equivalent cross sectional area). MT or PT is required for ferrous castings. For nonferrous castings. PT inspection is required only on submergence pressure boundary surfaces where stresses due to normal working loads would exceed 2/3 of the yield strength of the casting material : otherwise PT inspection is not required. Where NDT requirements of the component specifications differ from those specified in this table, the former shall govern. Exception: Subcategory 'D' NDT requirements shall apply to main feed water pump castings of design pressure of 550 Ib/in2 and greater. Refer to the applicable system or capponent specifications for pressure test requirements. Pressure test shall be conducted on uncoated castings. For hydraulic collponents with cylindrical datm features. this size is the largest diameter subject to normal operating pressure. For, components with non-cylindrical datum features, the size shall be the largest dimension of the 1 largest cross-sectional area subject to normal operating. pressure.
