[MW:20461] Query On QW- 403.5

Dear al,

could anyone please explain this clause from QW - 403.5. " when base metals of two different P-Number Group Number combinations are qualified using a single test coupon, that coupon qualifies the welding of those two P-Number Group Numbers to themselves as well as to each other using the variables qualified." i am not able to interpret the correct meaning of it.

regards,
Afees
