Full Title

Full titles differ between systems:

IPC:

Investigating fluid tightness of structures > by using fluid or vacuum > by measuring rate of loss or gain of fluid, e.g. by pressure-responsive devices, by flow detectors > for containers, e.g. radiators

CPC:

Investigating fluid-tightness of structures > by using fluid or vacuum > by measuring rate of loss or gain of fluid, e.g. by pressure-responsive devices, by flow detectors > for containers, e.g. radiators

CPC subdivides this area 6x more granularly than IPC with 5 additional codes.

5 codes are CPC-only extensions.
