[MW:7177] Mechanical Testing of Carbon Steel Plates as per ASME Section II-A

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 .
