[MW:7000] what is replacement for IIW welding quality Class system ?

Hello all,

 

Our companies old Fabrication specs were based on IIW welding quality class system eg. Welding quality class 1 , 2  .

But what I understood is that this system has been superseded .

 

What is the new equivalent weld quality system in place now.

 

Kindly advise.
