A typical blast mine consists of an explosive charge, detonator and a mechanical device to trigger the detonator. Blast mines are surface or subsurface buried, and are pressure activated. A test methodology must address four issues: 1) Consistency repeatability. 2) Transferability or the ability of many countries to implement test methodology
