RE: [MW:7179] Mechanical Testing of Carbon Steel Plates as per ASME Section II-A

SA 20 requires Mechanical testing on each plate as rolled (not per heat), mills provide plate numbers in addition to heat number on MTC and each plate will  be individually tested.
plate-as-rolled — the unit plate, as hot-rolled, prior to subdividing (if applicable) or any finishing operation.

Dear All ,
This is with reference to requirement of Mechanical Testing as per SA-20. In one of my equipment following thickness of SA 516 Gr 70 will be used : 16mm, 30mm, 45mm, 60mm, 90mm, 85mm.
 
Q1. If the mill produce all the above thicknesses from same heat, do we need to ask for mechanical testing of each thickness as per code or testing of any one plate will represent the all above thicknesses.
 
Q2. If simulation requirement is different for 16mm & 30mm Thick (10hours) and 12 hour for others.  The requirement is in as delivered condition and after simulated heat treatment. Whether one test on any thickness in as delivered and two different test for different simulation will be OK or not .
