Test setup for the leak test of the sample gas path and the flow-type reference gas path (dashed line) of the
ULTRAMAT 6F
Install the test setup as follows:
1. Close the sample gas inlet
2. Install a suitable shutoff valve (e.g. needle valve V1) of sufficient tightness into the sample
gas line downstream of the sample gas outlet
3. Connect a pressure regulator with a measuring range of 50 kPa and a resolution of 0.1 kPa
downstream of shutoff valve V1.
4. Proceed accordingly if the analyzer has a flow-type reference gas connection (
line). Close the reference gas inlet
gas outlet
5.2.3
Carrying out the leak test
Proceed as follows:
1. Carefully open the needle valve. A pressure is then built up in the containment system.
2. Once the test pressure has been reached (see following table), close the needle valve again.
3. Wait approx. 5 minutes. Thermal compensation is carried out in the analyzer during this time.
The temperature of the sample gas path must not change during the test!
4. Now determine the pressure change Δp during an additional 5 minute period.
The gas path is sufficiently leak-tight if the pressure change Δp in 5 minutes is less than the
test value listed in the following table.
