G01N 27/14

of an electrically-heated body in dependence upon change of temperature

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Investigating or analysing materials by the use of electric, electrochemical, or magnetic means > by investigating impedance > by investigating resistance > of an electrically-heated body in dependence upon change of temperature

CPC:

Investigating or analysing materials by the use of electric, electrochemical, or magnetic means (G01N3/00 – G01N25/00 take precedence; measurement or testing of electric or magnetic variables or of electric or magnetic properties of materials G01R) > by investigating impedance > by investigating resistance > of an electrically-heated body in dependence upon change of temperature

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

1 shared codes have differing titles between IPC and CPC.
