Comparison DIN - EN

The European standard EN 1092-1 / 11 has replaced the national standard DIN 2633 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.

Standards

DIN	EN
DIN 2633	EN 1092-1 type 11

In contrast to the DIN standard, EN-1092-1 only specifies the pipe connection dimensions of the ISO series.

It is therefore sufficient to stamp the nominal diameter (DN) for marking purposes.

Comparison DIN - EN

The European standard EN 1092-1 / 11 has replaced the national standard DIN 2633 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.

Standards

DIN	EN
DIN 2633	EN 1092-1 type 11

In contrast to the DIN standard, EN-1092-1 only specifies the pipe connection dimensions of the ISO series.

It is therefore sufficient to stamp the nominal diameter (DN) for marking purposes.
