Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Blasting cartridges, i.e. case and explosive > Initiators therefor > Safety initiators resistant to premature firing by static electricity or stray currents

CPC:

Blasting cartridges, i.e. case and explosive (fuse cords, e.g. detonating fuse cords C06C5/00; chemical aspects of detonators, blasting caps or primers C06C7/00) > Initiators therefor (percussion fuzes F42C7/00; percussion caps F42C19/10; electric primers F42C19/12) > Safety initiators resistant to premature firing by static electricity or stray currents

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1990.
