Is it your WPS need to be PWHT?. Supplementary essential variable. Then what kind of project you prepared for this WPS?. Is it needed for back gouging?. 400 mm x 300 mm shall be ok for all testing that you mention. A516 Gr 70 shall be ok for charpy -46deg. Make sure your consumable use also high in charpy value. E7018-1 check this electrode.

Dear Experts,
Our company is going to make a new PQR and WPS but since I am new at ASME sec IX and B31.3, I would like to verify my tests before doing them.
So PQR specs are;
Thickness 10mm (WPS qual. 10-15mm)
Mat Plate - SA516 Gr60 & SA516 Gr70 (this will qualify bot P1G1 and P1G2 mats right?)
Preheat 38°C Min(client spec)
Interpass Temp 250°C Max
PWHT 620°C (120min, 100°C/hr)
Pos 3G
Type GTAW + SMAW
Tests:
2 Tensile Test
2 Face Bend Test
2 Root Bend Test
4 Side Bend Test (Do we need this?)
5? Toughness Test (Charpy V-Noch at -46 C is enough?)
Hardness
Radiography
And the other thing is how big test coupon should I weld to get these tests. --
