F42 AMMUNITION; BLASTING
Description
F42 encompasses the design, manufacture, and function of ammunition and explosive devices used in firearms and blasting applications. This class covers cartridges, projectiles, propellant charges, detonators, fuses, and related components for small arms and larger weapons systems. It also includes blasting explosives, their initiation mechanisms, and techniques for controlled detonation in mining, construction, and demolition contexts. Adjacent classes address the weapons themselves (F41), while chemical explosives composition falls under C06B.
IPC and CPC are identically structured here. All 3 subcodes exist in both systems.
3 shared codes have differing titles between IPC and CPC.
