tks - I knew about the 56,600,PSI/57,000PSI & was most curious about these higher numbers listed:

PTc max= maximum average pressure, transducer, conformal (bar) 65,049.4254PSI

and

PK= 1,15 Pmax = maximum statistical individual pressure (bar) 70,705.8971PSI

I figured the 70,700 was a proof pressure.
