3.5 Field of application
3.5.1 Vessel
a) Single-walled (underground/above-ground), cylindrical tanks with
leak protecting lining (LPL) or leak protecting jacket (LPJ) and the
suction line up to the low point
Usage limits:
none in relation to density and diameter
b) Double-walled, horizontal cylindrical tanks (underground/above-
ground) (e.g. DIN 6608-2, 6616 or DIN EN 12 285-1-2)
- as with a), but without suction line to low point
- as with c), but without suction line to low point
- as with d), but without suction line to low point

For
underground
systems at least
density 1
is to be assumed.
In above-ground systems, the leak detector is to be fitted above
the top of the tank.
c) Double-walled (including single-walled with leak protecting lining or
leak protecting jacket) cylindrical standing vessels or tanks with
curved floors (underground/above-ground) with a suction line up to
the low point (DIN 6618-2: 1989)
2
Node point is the junction of the suction and measuring line with a vacuum leak detector for pipes. This can
also be in the assembly kit or a manifold.
