Amendment
to the certificate of approval from 1st February 2006 for the construction method
of a leak
detector as part of a leak detection device
for double-walled pipelines
File no. 0111BM21610
General technical approval no. Z-65.26-349
1. Procedure
In future, the DLR-GS leak detector will be equipped with electronic control
and signal processing. The alarm switching pressure switch can be adjusted
gradually to max. 16 bar via the micro selection switch on the board in the
leak detector. Other special control values are also possible after
consultation with the manufacturer.
2. Testing
Based on the documentation submitted and a design, the function and the
compliance with the Approval Guidelines for leak detectors for pipes (ZG-
LAGR), DIN EN 13160 and of the DIN VDE regulations was tested.
3. Result
From the point of view of the testing centre for leak detectors of TÜV
NORD, there were no concerns regarding the change in construction
method of the leak detector. The electronic components used have already
been tested in the context of the design test on the issue of general
building supervisory approval for the leak detector DLR-G .. The DLR-type
GS .. is merely a sub-variant that works without an integrated vacuum
generator. The pressure in the interstitial space is, as previously,
generated via a mobile printer memory. The switching values are adjusted
via a micro switch inside the device. For the operation and installation of
the leak detector DLRGS, the technical description of SGB
Gerätesicherungsbau GmbH from 25.04.2007 must be observed.
