Investigating concentration of particle suspensions (by weighing G01N5/00; investigating sedimentation of particle suspensions G01N15/04; investigating individual particles G01N15/10)

Introduced: September 1968

Title

Titles differ between systems:

IPC: Investigating concentration of particle suspensions

CPC: Investigating concentration of particle suspensions (by weighing G01N5/00; investigating sedimentation of particle suspensions G01N15/04; investigating individual particles G01N15/10)

Full Title

Full titles differ between systems:

IPC:

Investigating characteristics of particles; Investigating permeability, pore-volume or surface-area of porous materials > Investigating concentration of particle suspensions

CPC:

Investigating characteristics of particles; Investigating permeability, pore-volume or surface-area of porous materials > Investigating concentration of particle suspensions (by weighing G01N5/00; investigating sedimentation of particle suspensions G01N15/04; investigating individual particles G01N15/10)

CPC subdivides this area 9x more granularly than IPC with 8 additional codes.

8 codes are CPC-only extensions.

Note: 5 CPC extensions are marked as secondary classification only.

IPC defines codes here since 2024.
