The sand crush test is commonly employed to determine the relative brisance in comparison to TNT.

Brisance values are primarily employed in France and Russia.

Like gunpowder, cordite is classified as a low explosive because of its slow burning rates and consequently low brisance.
From the en.wikipedia.org
Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance.
From the en.wikipedia.org
Thus, brisance is a measure of the overall shattering ability of an explosive and is not necessarily correlated with the explosive's total work capacity.
From the en.wikipedia.org
It is a tertiary explosive consisting of distinct fuel and oxidizer phases and requires confinement for efficient detonation and brisance.
From the en.wikipedia.org
However, it is a very poor explosive compared to modern high explosives because it has a very slow decomposition rate, and therefore a very low brisance.
From the en.wikipedia.org
Brisance is of practical importance for determining the effectiveness of an explosion in fragmenting shells, bomb casings, grenades, structures, and the like.
