CVN requirement

Hi Experts,
My PQR qualified for A106 Gr.B with CVN requirement, but MTC material and consumable are not mention to impact test, So can i use this PQR for SA333 Gr.6 ?

My understanding question:

PQR qualified on pipe ASTM A106 Grade B, CVN at -xx degree C, material qualication did not undergo CVN test.
So, in this case, does WPS qualify for pipe material ASTM A333 grade 6, without CVN requirement?

Answer: I say yes because this material is the same P Number. You also consider welding consumable which suitable with design temperature or not?
