Introduced: July 1974
Title
Titles differ between systems:
IPC: outside of nuclear reactors or particle accelerators
CPC: outside nuclear reactors or particle accelerators
Full Title
Full titles differ between systems:
Arrangements for converting chemical elements by electromagnetic radiation, corpuscular radiation, or particle bombardment, e.g. producing radioactive isotopes > outside of nuclear reactors or particle accelerators
Arrangements for converting chemical elements by electromagnetic radiation, corpuscular radiation or particle bombardment, e.g. producing radioactive isotopes (separation of different isotopes of the same element B01D59/00) > outside nuclear reactors or particle accelerators
IPC and CPC are identically structured here. All 3 subcodes exist in both systems.
2 shared codes have differing titles between IPC and CPC.
IPC defines codes here since 1974.
