The vacuum stability test (VST) is considered the most acceptable test for measuring stability and compatibility of explosives, worldwide. This is an empirical test in which rate of gas evolution is measured under isothermal conditions and a limit of 01 cm3 of gas per gram of an explosive is set for explosives heated at 120°C (150°C for RDX) for 40h (25h for PETN). A similar test but at somewhat lower temperatures, is used to assess compatibility of an explosive with other explosives or with non-explosive materials such as binders (polymers), plasticizers etc. 

The explosion heat of tetrazene is rather low, i.e. 663 kcal/kg. This is characteristic of explosive substances containing a guanyl group in the molecule.

Tetramethylolcyclopentanone (III) is an intermediate product in the above reaction chain. It can be nitrated to give a tetranitrate, m.p. 74°C (nitropentanone). Friedrich and Flick report the explosion heat of nitropentanone as 820 kcal/kg, /= 10,680 m and the detonation rate 7940 m/sec at a density of 1.59 g/cm3. These substances are not in practical use at present. 

Attention was paid to the explosive properties of ammonium nitrate as early as 1883 by Berthelot [10] who first formulated the equation of decomposition, and gave the numerical data for the heat of explosion, heat of formation, the volume of gases evolved and the temperature of explosion. 

The mono- lithium, sodium, potassium and caesium salts of dinitrosomethane have been characterised. They are highly explosive, heat and shock sensitive. 

Diglycol dinitrate was used extensively in the Second World War by the German side as one of the main components of -> Double Base Propellants. The explosion heat of diglycol in powder form can be kept lower than the heats of the corresponding nitroglycerine powders they represented the first step towards the so-called cold powders. Diglycol dinitrate and triglycol dinitrate are also employed as rocket propellants. 

Cyclonite (RDX) and -> Octogen (HMX) as components for high-brisance compositions (- Compositions B — Hollow Charges) -> Nitroguanidine as the main component in powders with low explosion heat and in rocket propellants.
