Parallel electrode spark or streamer chambers; Wire spark or streamer chambers

Introduced: January 1980

Full Title

Full titles differ between systems:

IPC:

Tubes for determining the presence, intensity, density or energy of radiation or particles > Parallel electrode spark or streamer chambers; Wire spark or streamer chambers

CPC:

Tubes for determining the presence, intensity, density or energy of radiation or particles ( ; photoelectric discharge tubes not involving the ionisation of a gas H01J40/00 ) > Parallel electrode spark or streamer chambers; Wire spark or streamer chambers

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

IPC defines codes here since 1980.
