comments: Stepped up pressure pumping at 50 l/min. Held pressure at predetermined levels :
24 bar (gauge) - ok
33 bar (gauge) - ok
39 bar (gauge) - ok

At 46 bar gauge, i.e approx 53 bar (770 psi) differential, pressure bled of rapidly indicating burst disk rupture. Indications are that it is the shallowmost disk that ruptured.
