Abstract
A method of testing an explosive charge using a uniform shaped charge testing standard that is simulative of naturally occuring Berea sandstone test specimens. A quantity of zircon sand is mixed with from 3% to 8% by weight of the total mixture of a phenolic resin and then agitated to achieve desired density of the mixture for subsequent controlled heating to cure the mass into a molded shape suitable for explosives testing. An explosive shaped charge is detonated in the proximity of the standard, and the penetration of the shaped charge on the standard is measured.
