6.2.5.2. Main test
Immediately prior to commissioning and following the pressure test,
all pipelines, going as far as the closed instrument connectors of
the gas appliances, must be tested for tightness using air at an
overpressure of 150 mbar (TRF 2012). The pipelines are deemed
leak-proof if, following temperature equalisation, the test pressure
does not drop throughout the subsequent 10 minute duration of the
test.
Calling up the function:
> [] → Measurements → [OK] → Liquid gas (TRF) → Main
test → [OK].
