9.5.11 CO ambient

• Cigarette smoke influences the measurement by more than 50 ppm.
The breath of a smoker influences the measurement by about 5
ppm.
When using an ambient CO probe, note that:
•
The direction of flow of the gas has an effect on the accuracy of
measurement. Frontal flow onto the sensor leads to higher
readings. The best measurement results are achieved when the
probe is moved gently backwards and forwards.
When using the ambient CO probe and the flue gas probe, note
•
that:
The probe must be in the fresh air (CO-free) during the zeroing
phase.
For this type of measurement, the
also available. See Mean value calculation section.
An ambient CO probe (0632 1272) must be connected.

9.5.12 Pipe Commissioning (EU Regulation)

The pipe commissioning (using air or inert gas such as CO2 or N2) 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 2018 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.
