R. Meyer J. Köhler A. Homburg Explosives

Peroxides
charges of 40 cm in length in the groove; class III, the class of highest
safety, which must give no ignition in the angle-mortar test in position
B and with the groove filled over its full length with the explosive
charge (2 m, 6–1/2ft).
As an example for possible authorised applications a diagram of the
use of the German permitted explosives is given in Table 24.
Peroxides
Organic peroxides may act as explosive. They are usually not manufactured
for blasting purposes, but rather as catalysts for polymerization
reactions. They are utilized in a safely phlegmatized condition.
W Tricycloacetone Peroxide and W Hexamethylenetriperoxide Diamine
display properties of primary explosives.
