if plate is normalized SA-516-70,dish head 2.1 is cold formed and then head is normalized due to extreme fiber elongation. do we need test secimens be tested to satisfy UCS-85?

RE: UCS-85
UCS-85(i) All thermal treatments which precede a thermal
treatment that fully austenitizes the material need not
be accounted for by the specimen heat treatments, provided
the austenitizing temperature is at least as high as any of
the preceding thermal treatments.

So the only test specdimens required would be of material Normalized prior to forming. UCS85(i) exempts the re-testing of specimens("need not account for"), any heat treat done at or above the initial heat treatments and performed above 900F.
That is how I interpret the question.
