Re: [MW:22840] Fw: QW 403.6. QW451, QW401.3 notch toughness, combination PQR's

Q1:  since full mechanical tests are not done on 5mm coupon, the combination will qualify from 5mm and not 2.5mm (QW451.1)

Dear All,
 
I have one query regarding below ASME IX interpretation.
 
How come this three PQR jointly will support a WPS with notch toughness test for thickness 4.8 mm to 57 mm? if your answer is also yes, than why answer is No for first question?

Appreciate your expert reply.
