1.
Approval item and scope of application
1.1
The subject of this general building inspectorate approval is an overpressure
leak detector type designations DL.. (with integrated pump) and DLG.. (with
integrated compressed gas supply) with the design variants for alarm pressure
switching values of > 50 mbar, > 100 mbar, > 290 mbar, > 330 mbar, > 400
mbar, > 450 mbar, > 590 mbar, > 750 mbar, > 1000 mbar, > 1100 mbar, >
1500 mbar, > 2000 mbar, > 2300 mbar, > 2500 mbar and > 3000 mbar
overpressure.
1.2
The leak detectors may be connected to suitable interstitial spaces of double
walled tanks, tanks with leak detection lining or leak detection jacketing,
sumps and containments for plant for the storage, filling and transhipment of
water polluting liquids (structure of the leak detection system see Annex 1).
1.3
Suitable interstitial space refers to interstitial space with a volume of up to 8 m³
rated with an interstitial space test pressure corresponding to the specific
design variant of the particular leak detector.
1.4
The general building inspectorate approval is issued notwithstanding test or
permit reservations in other legal areas (e.g. 1
st
Ordinance on the Machine
Safety Law – Low Voltage Ordinance – Law on Electromagnetic Compatibility
of Machines – EMC - , 11
th
Ordinance on the Machine Safety Law – Explosion
Protection Ordinance).
1.5
With this general building inspectorate approval, the approval item is not
required to undergo specific water suitability testing and type approval as per §
Law 19 h of the Water Resources Act (WHG)

Stipulations for the product
2.1
Properties and composition
2.1.1 A leak in the walls of the interstitial space is indicated visually and audible
when pressure falls to the alarm switching value.
2.1.2 The leak detector consists of the display and control elements, the
overpressure pump with upstream dry filter or a permanently connected
pressure cylinder or operational pressure network with inert gas or dried air,
the pressure and measuring lines with shut-off and safety valves, the pressure
sensor and electrical control components. The parts and components are
stated in the Technical Description
. To protect the interstitial space from
intolerable overpressures, the overpressure valves are adjusted to the opening
pressures stated in Annex B to the Technical Description.
