GENERAL NOTES:
(a) For temperature limitations, see notes in ables ll-2-1.1 through l-2-3.17 of Mandatory Appendix ll.
(b) Plate materials are listed only for use as blind flanges and reducing flanges without hubs (see para. 5.1). Additional plate materals listed in ASME B16.34 may also be used with coresponding B16.34, Standard Class ratings.
NOTE:
(1) ASlE Boller and Pressure Vessel Code, Section ll materials may also be used, provided the requrements of the ASME specification are identical to or more stringent than the corresponding ASTM specification for the Grade, Class, or Type listed.
