what is the material type IQI should i choose?

i just have a weld like this, the material of one side is ASTM A694 F65 with 3mm(CRA),
the other side is DNVGL 450 FD also with 3mm(CRA),i have found nothing about DNVGL 450FD on internet,can anybody tell me more about it?
the filler metal is inconel 625 ,the weld thickness is 60mm.
my guys have take a shoot on this weld with the IQI type 1(carbon steel type), the client representative told me i should follow ASTM 74,Materials Group 3:7.2.6.1 Image quality indicators (IQI’s) shall be made ofnickel-chromium-iron alloy (UNS No. N06600) (Inconel).6.
so what is the material type IQI should i choose?
the weld thickness is 60mm, It cost too much time, if i don't want to shoot it again? can any experts gives me some advice to persuade the client representative?

If you took shot with Group 1 - CS and can see the essential wire, then you are covered for Group 3 (Ni-Cr). CS is more difficult to see than Ni-Cr. You can refer to the X-Ray attenuation coefficients

yep,that's make sense.'thank your advice. but the representative insisted its opinion and the component has been tied out to the barge. so it will be reshoot offshore or carried out paut.
