G01N 29/028 by measuring mechanical or acoustic impedance
Introduced: January 2006
Full Title
Full titles differ between systems:
IPC:
Investigating or analysing materials by the use of ultrasonic, sonic or infrasonic waves; Visualisation of the interior of objects by transmitting ultrasonic or sonic waves through the object > Analysing fluids > by measuring mechanical or acoustic impedance
CPC:
Investigating or analysing materials by the use of ultrasonic, sonic or infrasonic waves; Visualisation of the interior of objects by transmitting ultrasonic or sonic waves through the object (G01N3/00 - G01N27/00 take precedence) > Analysing fluids (using acoustic emission techniques G01N29/14 ) > by measuring mechanical or acoustic impedance
No child classifications to compare. This is a leaf node in both IPC and CPC.
