[MW:4281] RE: 4279] Supporting WPS

No - See Sc. IX, QW-424.1

 

"Base metals are assigned P-numbers in table QW/QB-422;  metals that do not appear in table QW/QB-422 are considered to unassigned metals except as otherwize defined for base metals having the same UNS numbers.  Unassigned metals shall be identified in the WPS and the PQR  . . . "

 

In the list in QW-424.1,  an unlisted material used for a PQR test only qualifies the unassigned material.
