Approval no. Z-40.21-365, January 14, 2005
Manufacture, packaging, transport, and storage
1
Manufacture
1.1
PE inner container
(1) The containers must be manufactured in the same manuf-
acturing facilities where the containers tested for the proof of
suitability were produced.
(2) The container surface may not be chemically treated if
this treatment is not a component of the General Construction
Inspection Approval.
(3) If the blowing facility has changes (such as on the extruder,
blowing head, or blowing mould) the certifi cation agency is to be
informed, who will then make a decision about how to proceed.
(Involving the DIBt, special tests)

Packaging, transport, storage
2.1
Packaging
Packaging the containers for the purpose of transport or (tem-
porary) storage is not necessary if the requirements of Sec. 2.2
are met. The openings of all connection muffs must be closed by
screwing on their caps.
2.2
Transport, storage
2.2.1 General instructions
Transport must be carried out by only those companies with
specialist experience, suitable machinery, equipment, and
means of transport, and suffi ciently trained personnel. To avoid
hazards for employees and third parties, the applicable accident
prevention directives must be observed.
2.2.2 Transport preparation
The containers must be prepared for transport so that no dama-
ge occurs during loading, transport, and unloading.
The loading surface of the transport vehicle must be constructed
so that it is not possible to damage the containers by impact or
pressure against a pointed object.
2.2.3 Loading and unloading
When lifting, moving, and setting down the containers, impact
loads must be avoided.
If a fork lift truck is used, the containers must be secured during
the moving with the fork lift.
Connection pieces and protruding parts of the containers may
not be used as lifting points for the containers. The containers
may not be dragged across a fl oor or the ground.
2.2.4 Carriage
The containers must be secured against unacceptable shifts of
position during carriage. The mode of fastening may not cause
the containers to be damaged.
2.2.5 Storage
When temporarily placed outside, the containers should be pro-
tected against damage and storms. Containers are not permitted
to be exposed to weathering for more than six months.
2.2.6 Damage
When damages occur from transport or storage, the course of
action should be based on the fi ndings of an expert in water
directives or the certifi cation agency.

Approval no. Z-40.21-365, January 14, 2005
Installation conditions
1
General
(1) The container installation must follow Secs. 3 and 4 of the
Particular Regulations of this General Construction Inspection
Approval.
(2) In high water or fl ooding areas, the containers must be
placed so that they cannot be reached by high water.
2
Bearing surface
The containers must be placed completely on a fl at, hard
(unbending) smooth support slab or a carefully compacted and
hardened support surface.
3
Distances
(1) The containers must be at a distance from walls, other
construction, and each other that leakage may at any time be
detected by visual inspection. The containers must be placed so
that risk of explosion is suffi ciently small and means to extingu-
ish fi re are suffi ciently available.
(2) The following clearances are generally required for contai-
ners used to store EL grade heating oil according to DIN 51603
and diesel fuel according to DIN EN 590:
The containers must have an access clearance of at least 40
cm on one side. The spacing from the remaining walls must be
at least 5 cm.
4
Setting up
The containers must be installed level and plumb at their loca-
tion. The installation instructions delivered with the containers
(see Sec. 5.1.4) must be followed.
5
Connecting pipelines
(1) When connecting pipelines to the container connection
muffs, give attention that nothing is forced and that no
additional external loads that are not designed to act on the
containers are generated.
(2) If a permanently laid pipeline is connected to the container,
it must satisfy the requirements of TRbF 50
test pressure of 10 bar.
(3) Pipelines for introducing and releasing air must conform to
TRbF 22011 Nr. 6.1, be of adequate dimensions, and may not
have a cut-off possibility. They and their pipe connections
must be designed so that they remain leak proof at 0.3 bar
overpressure.
Several containers may be connected to the same ventilation
and exhaust pipeline only if the liquids they will store and their
vapours do not combine to make dangerous compounds.
Lines or equipment for fl ushing with air or de-airing must not
discharge into closed rooms. This does not apply to contai-
ners for storing heating oil according to DIN 51603 and diesel
fuel according to DIN EN 590.
The outlet openings must be protected from rainwater.
