Full titles differ between systems:

IPC:

Details of transit-time tubes of the types covered by group > Coupling devices having distributed capacitance and inductance, structurally associated with the tube, for introducing or removing wave energy > to or from the interaction circuit > for linking interaction circuit with coaxial lines; Devices of the coupled helices type

CPC:

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1985.
