Testing Sewage Lines - Dräger P7-TDX Instruction Manual

Instruction Manual Dräger P7-TDX

12. Testing sewage lines

The tightness test for sewage lines according to DIN EN 1610 applies to new and refur-
bished sewage lines and sewers.
For the test using air (method L), the initial pressure, which exceeds the required test
pressure by approx. 10 %, must be initially maintained for approx. 5 minutes. After that,
the test pressure must be set according to test method LC (100 hPa (mbar)) or
LD (200 hPa (mbar)). In case the drop in pressure measured
after the test time is lower than 15 hPa (mbar) for both these
test methods, the pipeline complies with the requirements.
Select the material of the sewer pipe and the test method.
The following materials and test methods can be selected:
Cement dry LC 100 hPa (mbar) =
Cement dry LD 200 hPa (mbar) =
Cement wet LC 100 hPa (mbar) =
Cement wet LD 200 hPa (mbar) =
Select pipe diameter and start.
The selected material, the test method and the test pressure
resulting from this data, the stabilization period and the test
time are shown.
