Theo,

First, thanks for the paper and your response on AD-Merkblatter.

Few doubts:

1) You have mentioned that for Flange analysis AD-2000 Refers to DIN 2505.

Also you have mentioned that AD-2000 also has a simplified conservative procedure, compared to DIN 2505, for Flange analysis.

Does that mean AD Merkblatter has both options: Flange analysis as per DIN 2505 as well as by it's own method? If so which method does it recommend?

2) Is EN13445 a separate document from AD-Merkblatter ?

For EN1591 and it's comparison to Taylor Forge method, you can see ( in case you already have not seen) a good paper by Yann Guérout
in www.sealeng.com.
