C06 EXPLOSIVES; MATCHES
Description
C06 covers the chemistry, manufacture, and composition of explosives, propellants, pyrotechnic compositions, and matches. This includes gunpowder, dynamite, detonators, fuses, and various chemically-reactive substances designed for controlled or uncontrolled rapid energy release. The class encompasses manufacturing methods, safety devices, and ignition systems for these materials, as well as the chemical formulations and stabilization techniques used in their production. Matches and related friction-ignition devices are included as a distinct but related application area.
