Measuring magnetic properties of articles or specimens of solids or fluids (involving magnetic resonance G01R33/20)

Introduced: September 1968

Title

Titles differ between systems:

IPC: Measuring magnetic properties of articles or specimens of solids or fluids

CPC: Measuring magnetic properties of articles or specimens of solids or fluids (involving magnetic resonance G01R33/20)

Full Title

Full titles differ between systems:

IPC:

Arrangements or instruments for measuring magnetic variables > Measuring magnetic properties of articles or specimens of solids or fluids

CPC:

Arrangements or instruments for measuring magnetic variables > Measuring magnetic properties of articles or specimens of solids or fluids (involving magnetic resonance G01R33/20)

CPC subdivides this area 5x more granularly than IPC with 11 additional codes.

11 codes are CPC-only extensions.
