It must be ensured that, under repeated filling conditions, the filling level
difference between the containers does not exceed 100 mm.

Connecting pipelines
(1) When connecting pipelines to the container connecting union,
ensure that undue force is not required and that no additional
external stresses result which then act on the container in an
unintended manner.
(2) If a fixed pipeline is connected to the container, it must satisfy
the requirements of TRbF and withstand a test pressure of 10 bar.
(3) Flushing- and ventilation lines must conform to TRbF 20
9.1.2, must have adequate dimensions and must not be able to
be blocked. They and their pipeline connections must be set up so
that they remain leak proof with 0.3 bar overpressure.
Several containers may be -connected to the same flushing and
ventilation pipeline, only if the liquids they will store and their
vapours will not combine to produce dangerous compounds.
Lines- and equipment for flushing and ventilating must not
discharge into closed spaces.
The outlet openings must be protected from rainwater ingress.
