Introduced: September 1968

Title

Titles differ between systems:

IPC: Analysing solids

CPC: Analysing solids (using acoustic emission techniques G01N29/14)

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

CPC:

Of 9 combined children, 5 exist in both systems.

4 codes are CPC-only extensions.

IPC defines codes here since 1985.
