6.2.17.1. Tightness test 1
Leak test on gas pipes acc. to DVGW-TRGI 2008
worksheet G600
The leak test (using air or inert gas, e.g. CO2 or N2) is used
for acceptance testing of newly routed or remedied pipes.
The test is performed at the pipe, including the fittings,
without gas installations and corresponding control and
safety equipment. For this test the line must be pressurised
with 150 mbar, whereby this pressure must remain constant
for 10 minutes.
This applies to lines < 100 l. For larger line volumes, the
stability time and measurement period should be adjusted
in accordance with DVGW-TRGI 2008 worksheet G600.
