by measuring propagation velocity or propagation time of acoustic waves

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 solids > by measuring propagation velocity or propagation time of acoustic waves

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 solids (using acoustic emission techniques G01N29/14) > by measuring propagation velocity or propagation time of acoustic waves

Of 1 combined children, 0 exist in both systems.

1 codes are CPC-only extensions.
