Pipe Commissioning (EU regulation)
The pipe commissioning (using air or inert gas such as CO
2
or N
2
) is a tightness
test for pipes, including fittings, but without gas appliances and the relevant
regulating and safety devices. The pipe commissioning is performed after a load
test has been successfully completed on newly laid gas pipes, or after
renovation of existing gas pipes, and is used for the acceptance of these pipes.
It shows up even the smallest leaks in gas pipes.
According to DVGW TRGI 2008 and ÖVGW G10, the stabilization time
and test time depend on the pipe volume.
- Pipe volume < 100 l: Adjustment time 10 min, test time 10 min.
- Pipe volume > 100 l to < 200 l: Adjustment time 30 min, test time
20 min.
- Pipe volume > 200 l: Adjustment time 60 min, test time 30 min.
Connect the connector plug of the hose pressure connection kit (0554
1203) to the pressure test kit (0554 1213). Insert the pressure adapter
into the flue gas socket and lock by slightly turning it clockwise (bayonet
fitting).
Performing the measurement
The pressure socket of the instrument must be free (depressurized, not
closed).
Pressure zeroing has been performed.

Set parameters or enter values.
All values that can be modified have a dotted underlining.
Once the pressure has built up, a stabilization time specified by DVGW-
TRGI 2008 should be observed to ensure that any possible pressure
fluctuations are not recorded in the measurement as well. The relevant
standard provides more detailed information.
Start stabilization time: tap . If applicable, follow instructions.
