Page 4 of the notification dated 23 June 2008 regarding the amendment to the General Construction Inspection
Approval No. Z-40.11-280 dated 30 January 2001
Section 5.1.4 is replaced by the following section:
5.1.4 Documentation
The container manufacturer must supply the following documents to the operator:
- A copy of this General Construction Inspection Approval or an approved excerpt of it;
- A copy of the General Construction Inspection Approval for the limit value transmitter and overfill guard
suitable for the intended use;
- Installation instructions for installing the individual tank and/or the tank system.
If a leak detector is connected to the monitoring chamber, the operator must also be provided with a copy
of the General Construction Inspection Approval issued by the general building inspectorate for the leak
detector suited for the intended use.
The first bullet point of Section 5.1.5.2 (Filling and Emptying), Paragraph (4), is replaced by:
- Filling system (filling, ventilation, emptying) as per Section 5.1.1(7),
Paragraph (2) of Section 5.3.2 (ongoing tests / commissioning tests) is replaced by the following paragraph:
(2) If a leak detector is connected to the monitoring chamber, the functionality of the leak detector must
be tested in accordance with the specifications of the General Construction Inspection Approval issued
by the building inspectorate.
The appendix 1.17 is supplemented.
Section 1 (Manufacture) of Appendix 4 (Manufacture, Packaging, Shipping and Storage)
is replaced by the following section:
1 Manufacture
The tank consists of an internal and external floor shell, an internal and external shell laminate and a
single-walled cover shell. The internal and external floor shells as well as the cover shell are manufactured
using a pressure-injection process (resin transfer moulding) or a wet press process.
Because both the internal and external walls are translucent, the filling level of the stored medium is
visible from the outside. To facilitate reliable detection of a leak in the internal wall even in tanks without
attached leak indicators, a non-transparent strip of non-woven material is attached to the internal wall
of the tank. If the stored fluid is visible in the area of this non-woven strip, the internal wall is leaking.
This visual leak detection is described for the operator of the tank system on a sticker attached to the
tank wall (see Appendix 1.17).
The processing and finishing guidelines and/or recommendations of the material manufacturer must be
observed.
The description of the manufacturing process is on file at the German Institute of Structural Engineering
(DIBt).
