You reference table 323.3.1, but mention B31.1. Can we assume youre using B31.3?

/edt. Table 323.3.1 is for the size of the specimen to be impact tested: one piece (thickness T) for each range of thickness T/2 to T + 6 mm.

Thank you for the reply?
In which cases QW-403.6 applies?

If the project is built in accordance with B31.3, then the T/2 to T + 6mm rule applies.
