* For flanges type 21 the outside hub diameter approximately corresponds to the outside pipe diameter. 
Note : The p/t rating from EN 1092-1 apply only for flange type 05, 11, 12, 13 and 21 having nominal sizes up to and including DN 600. The p/t rating of all other flanges shall be agreed between the manufacturer and the purchaser.

Plate flange PN 16 – acc. to EN 1092-1 type 01

Comparison DIN and EN                                                                                                                                                  
For nominal sizes larger than DN 150, EN standardizes pressure levels PN 10 and PN 16.
From DN 50 to DN 150, the EN refers to the standard series of PN 16 pressure level.
For dimensions up to DN 40, the EN refers to the standard series of PN 40 pressure level.
New in EN 1092-1 are the pressure levels PN 16 and PN 40 for plate flanges.
The European standard EN 1092-1/01 has replaced the national standard DIN 2576 in 2007.

Standards

DIN (old)

   EN (new)

EN 1092-1 type 01 PN 16

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.
