Page 5 of the General Building Inspectorate Approval No. Z-65.23-409 dated 5 April 2005
The records are to be kept for at least five years. They are to be submitted to
the German Institute for Building Technology and the highest building
supervisory authorities on demand.
In the case of unsatisfactory test results, the manufacturer must introduce
immediate measures to eliminate the defects. Leak detectors which fail to
comply with requirements must be handled in such a way so as to rule out any
risk of confusion with conforming approval items. After eliminating the fault, the
corresponding test must be repeated immediately insofar as technically
feasible and required as verification that the fault has been eliminated.
2.3.3 Type testing by acknowledged testing agency
Type testing includes the function tests stated in the "Approval principles for
leak detection systems for tanks". If verification according to the general
building inspectorate approval has been obtained in samples from on-going
production, the corresponding tests replace type testing.
3.
Stipulations for the design
3.1
(1) Care must be taken to ensure that the leak detector is adequately resistant
to the liquid being stored and that the water polluting liquid does not react with
the leak detection medium.
3.2
The limits of operation of the leak detectors to ensure that the alarms are
given are stated in Annex B of the Technical Description with reference to the
maximum effective liquid pressure on the bottom of the tank (static pressure of
the stored liquid plus overlay pressure) depending on the alarm switching
value of the leak detector version.
3.3
The leak detector must only be connected to several interstitial spaces in the
case of underground tanks. The shut-off valves for every connected tank must
be set to "open" when the leak detector is operating.
3.4
Connection of the leak detectors to tanks as per section 1.2 for the storage of
liquids with flash points < 55°C is only permitted if the operating modes stated
in the Technical Description with safeguarded refilling or without safeguarded
refilling with the use of inert gas or dried air as leak detection medium, comply
with the requirements made in Annex B of DIN EN 1310-1
equipment categories as per EN 1127-1
Refilling as per Annex B of DIN EN 13160-1 with air or inert gas as leak
detection medium (monitoring medium) is said to be safeguarded
-
if the leak detector has an integrated pump
-
if the leak detector is connected to a permanently operating
compressed air or gas network suitable for operation of the leak
detector
