Jop I don’t think your table is the European Standard, as I said above – In the European standard EN 1092-1 (old DIN) an ASME 600# Flange is equivalent to a PN 40 Flange.

At least this makes some sense as the European PN units are bars and 40bar=580psi
So what is the basis of your table where ASME 600# is equivalent to PN 100?
