Yes,values(Class Rated)given in Table 2-1.1(ASME B16.5)is matching with values(PN Rated) given in Table E.5(ISO 7005-1:1992).
Hence, we can corelate this Class-PN relation for flanges.
Also same values are also matching with values(Class Rated) given in Table 2-1.1 (ASME B16.34).

Hi folks,

Is there any code/standard specifying it? Can we take as basis for class vs pressure design consideration...
