Hi

The SIF for EN13480-3 are in Annexe H in table H1 and H3. These are more or less copies of ASME B31.1 and B31.3.
The table H1 has only 1 SIF for the resultant moments:

wheras H3 has inplane and outplane SIFs.
TableH3.jpg
There is no limitation in EN13480-3 on the use of these tables.
Weldolets are only available in table H3. The abbreviation in ROHR2 is TWA and it corresponds to line 9 in table H3:

Best regards
