Introduced: September 1968
Full Title
Full titles differ between systems:
IPC:
Investigating flow properties of materials, e.g. viscosity or plasticity; Analysing materials by determining flow properties > by moving a body within the material
CPC:
Investigating flow properties of materials, e.g. viscosity, plasticity; Analysing materials by determining flow properties > by moving a body within the material
Of 4 combined children, 3 exist in both systems.
1 codes are CPC-only extensions.
2 shared codes have differing titles between IPC and CPC.
