12. Drop hammer and lead tube tests have been carried out by Nippon Carlit Co. Ltd. at our request. The numerial values of the drop hammer test indicate how easily the sample explodes by the shock of the drop of the hammer: lower hight, more sensitive to the shock. The value for the 70 wt% solution of 2 is less than hight of 10 cm and for the isolated 3 it is more than 100 cm to explode by the shock of the drop of a 5-kg hammer. For other well-known explosive compounds, for example, for nitroglycerine it is 4 cm, it is 57-90 cm for TNT, and 100 cm for black gunpowder explode by the shock of the drop of a 2-kg hammer. The numerial values of lead tube test indicate the violence of explosion when the sample explodes by ignition: larger value indicates greater violence. The value for the 30% solution of 2 is 11.3 and for the pure and dry 3 it is 70 as a number of the violence. For other well-known explosive compounds, for examples, 250-400 for general gunpowder and 80 for black gunpowder.
