EXPLOSIVE CHARGES, e.g. FOR BLASTING, FIREWORKS, AMMUNITION (explosive compositions C06B; fuzes F42C; blasting F42D)

Description

F42B covers explosive charges and their applications across multiple domains: industrial blasting operations, fireworks and pyrotechnic devices, and ammunition for weapons systems. This subclass includes the design, composition, and construction of explosive devices, detonation mechanisms, and related safety features. The classification encompasses both conventional explosives and specialized charges for specific industrial or military purposes, excluding the weapons platforms themselves and general ammunition propellants covered in adjacent classes.
