Tolerance for Thickness of Clad Plate

My project is H/EX with application for ASME SEC VIII Div.2 2007 ED + 2009 ADD.

i received material for carbon steel(SA516-70,58mm) + clad plate(347 SS,6mm)

and then i inspected thickness of this material with thickness gauge when MI(Material

Inspection). but i didn't' know tolerance for thickness of clad plate.

i want know tolerance for thickness of clad plate at ASME CODE .
