[MW:0] Supporting PQR for Impact requirements

Dear All, 

I have Qualified PQR for welding P1 Gr 1 To P1 Gr 1 with Impact test at (-) 51°C 
thickness range 2.77 to 11.08 mm.
But now we have to weld P1 Gr 1 to P1 Gr 2. Can I do one more supporting PQR with with P1 Gr 1 to P1 Gr 2 With only impact testing.
Please clarify whether Tensile test and bend test are mandatory for supporting  PQR.


Thanking you.
