(OP)
When qualifiying welding procedures to ASME Sec. IX can materials listed with S No.'s only (Example A572-50 S-1) be grouped with corresponding P No.'s? QW 420.2&3 addresses this issue but seems to me to be unclear. Any assistance will be apprecaiated.

Ps will qualify other Ps and Ss in the same group. Ss will qualify other Ss but not Ps in the same group.
