*For non-gassed products only. The density of gassed products varies according to depth in an explosive column
and the open cup density. Please consult the "Gassing density for Titan blends" table for further information.
Calculation Kg/m = 3.14159 x D2 x P / 4,000 Where D is the hole diameter in mm P is the explosive density in g/cm3 To determine the loading factor for explosive densities not listed, select the loading factor for the size hole in the 1.00g/cm 3 column then multiply it by the required density in g/cm3 .
