M6 blasting cap or equivalent shall be secured against the middle of the 3 inch side of the
charge, and the assembly shall be mounted in a steel water tank capable of being pressurized to
10,000 psi. The charge shall be detonated after 45 minutes under a measured 10,000 psi
hydrostatic pressure, at ambient temperature. After detonation, the witness plate shall be
