[MW:30197] AWS D1.1 WPS qualification range for base material

I have to qualify a PQR in following conditions

Construction Code AWS D1.1
Material API 5L Gr B
Welding position 6GR
Base material
Diameter 6"
Thickness on none bevel end = 14.27 mm
Thickness on bevel end = 7.11 mm

Query

1.  What should be the thickness Range for WPS without CVN testing ?

2.  What should be the thickness Range for WPS with CVN testing ?

Looking forward for support with Clause reference if possible.

Regards,
Prashant
