Re: [MW:34190] Impact Testing requirements for PQR

Appreciate efforts and initiative from ENG.Ahmed.

Just to share. 2 PQR's 6mm & 23mm is sufficient.

There is an ASME Interpretation stating PQR qualified on 6mm and higher thickness qualifies in the range from 16mm.  Someone please share the Interpretation.

Thanks & Regards
