The European standard EN 1092-1/01 has replaced the national standard DIN 2576 in 2007.

For dimensions up to DN 40, the EN refers to the standard series of PN 40 pressure level.

From DN 50 to DN 150, the EN refers to the standard series of PN 16 pressure level.

For nominal sizes larger than DN 150, EN standardizes pressure levels PN 10 and PN 16.
