January 14, 2005
(2) For a certifi cate of conformity to be granted and the external
monitoring including the required product test, the manufacturer
of the containers must use the services of a certifi cation agency
and a monitoring agency recognised for these purposes.
(3) The certifi cation agency must give a copy of the conformity
certifi cate to the DIBt.
A copy of the fi rst test report must also be given to the DIBt.
2.3.2. Manufacturer's in-house production control
(1) The manufacturer must initiate and carry out production
control in every production plant. Manufacturer's in-house
production control means here the required continual monitoring
of production which assures that the containers manufactured
there comply with the conditions of this General Construction
Inspection Approval.
(2) The in-house production control should include at least the
tests listed in Annex 4, Sec.1.
(3) The results of the in-house production control must be
recorded and analysed. The records must contain at least the
following data:
- Designation of the product produced or the starting material
- Type of control or test
- Date of manufacture and of testing of the product or the starting
material, or its constituent components
- Results of the controls and tests and comparison with the
requirements
- Signature of the person in charge of the in-house production
control.
The data logs are to be kept at least fi ve years and must be com-
municated to the external monitoring agent. On request they
are to be shown to the DIBt and the competent highest building
supervisory agency.
For unsatisfactory test results, the manufacturer must immedi-
ately take the necessary steps to remedy the defect. Products
that do not meet specifi cations must be handled so that they
cannot be confused with compliant products. After the defect is
remedied, the failed test must be repeated as soon as technically
possible.
2.3.3 External monitoring
(1) In every manufacturing plant, the in-house production control
is to be externally monitored as in Annex 4, Sec.2 (2) at regular
intervals, at least twice per year.
(2) As part of the external monitoring, a fi rst test of the contai-
ners as in Annex 4, Sec. 2 (1), s to be performed. In addition,
samples for random testing can be taken. The sample taking and
tests are the responsibility of the recognised monitoring agency.
(3) The results of the certifi cation and external monitoring are to
be kept for at least fi ve years. The certifi cation agency and the
monitoring agency must present them on request to the DIBt and
the competent highest building supervisory agency.

Conditions for design and measurement
(1) For behaviour withstanding fl ames, see Sec. 2.1.4.
(2) The conditions for installing the containers are found in the
water, work safety, and construction directives.
In addition the requirements of Annex 5 apply.

(3) The containers must be protected against impact by vehicles,
for example by installing in protected places, use of collision
guards, or installing in a suitable collecting area.
4
Conditions for implementation
(1) Installation of the containers is subject to Annex 5.
(2) Installation and placement of the containers must be carried
out by only those businesses which are specialists for this work
in the meaning of § 19 I Water Resources Act, unless these
tasks are excepted from requiring specialist companies in state
regulations.'
(3) The installing company must certify that installation was
proper, observing the manufacturer's instructions (see Sec.
5.1.4) and those in Annex 5.
(4) Containers damaged in transport or installation may not
be used if the damage compromises the leak tightness or the
mechanical stability of the containers.
(5) Repairs to the internal container are not allowed.
(6) Assessment of damages and steps to remedy damages
should be made in consultation with an expert in water directives
or the certifi cation agency.

Conditions for use, maintenance, servicing, und testing
5.1
Use
5.1.1 Equipping the containers
(1) The conditions for equipping the containers are found in the
water, construction, and work safety directives. If there are no
water or construction directives for equipping containers to store
non-combustible liquids, Sec. 9 of the Technical Regulations for
Combustible Liquids (TRbF) 20
(2) Accessories must be designed to avoid unacceptable high
or negative pressures and unacceptable loads on the container
wall.
(3) The containers will be equipped with a leak detector of type
"LS-3" with the general construction inspection approval no.
Z-65.40-256. The containers may also be equipped with another
leak detector suited for the intended use if it has received a
general construction inspection approval.
5.1.2 Stored liquids
It is not permitted to store the liquids listed in Sec. 1 (3) if they
are mixed with one another or with other substances, or if a
different liquid has already been stored in the container.
It is not permitted to store contaminated liquids if the contami-
nants would lead to altered material behaviour.
5.1.3 Usable container volumes
The allowed container fi lling volume does not exceed 95 %, un-
less a different fi lling volume is proven acceptable or is required,
referring to TRbF 20 Nr. 9.3.2.2. If there is a safety device for
avoiding overfi lling, it must be set to the acceptable value.
5.1.4 Documentation
The container manufacturer must supply the following docu-
ments to the operator:
- A copy of this General Construction Inspection Approval or an
approved excerpt of it;
7
„Technische Regeln für brennbare Flüssigkeiten" („Technical Regula-
tions for Combustible Liquids"), TRbF 20 issued April 2001, „Storage
Areas"
should be followed.
