Please note as per Clause QW200.4(b) of ASME IX, these PQR's cannot
be combined.
Only When the "T" ≥ 13mm in both the PQR's, then the combination of
PQR's are allowed
In addition to the above
when impact is required :
Please note as per QW-403.5 combination of PQR'S are allowed when
both the qualification records have the same essential & supplementary
essentials except the basemetals assigned with different group Nos.
within the same P. No.
When impact is not required :
These qualification records with basemetals of different Group Nos.are
allowed to combine.
