Introduced: September 1968

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

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

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.
