DIFF Subgroup
G01N 23/083 the radiation being X-rays
Introduced: January 1990
Full Title
Full titles differ between systems:
IPC:
Investigating or analysing materials by the use of wave or particle radiation, e.g. X-rays or neutrons, not covered by groups , or > by transmitting the radiation through the material > and measuring the absorption > the radiation being X-rays
CPC:
Investigating or analysing materials by the use of wave or particle radiation, e.g. X-rays or neutrons, not covered by groups G01N3/00 – G01N17/00, G01N21/00 or G01N22/00 > by transmitting the radiation through the material > and measuring the absorption > the radiation being X-rays
IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
IPC defines codes here since 1990.
