Manufacturing requirements
1.1
PE interior containers
(1) The containers must be manufactured in the same manufacturing facilities where the
containers tested for the proof of suitability were produced.
(2) The surface of the container may be treated subsequently for permeation-resistance.
(3) If the blowing facility undergoes changes (e.g. on the extruder, blowing head or blowing
mould) or if the chemical treatment applied subsequently changes, the certification agency
must be informed, which then makes a decision about how to proceed (involvement of the
DIBt, special inspections).
1.2
Steel sheet collector container (galvanised)
(1) Production must be according to the manufacturer description.
(2) Any change in manufacturing technology, the material or the sealant requires approval of
the DIBt and amendment of this national technical approval.

Packaging, transport, storage
2.1
Packaging
It is not necessary to package the containers for the purpose of transport or (temporary)
storage if the requirements of Section 2.2 are met. All nozzle openings must be closed by
screwing on the caps.
2.2
Transport, storage
2.2.1
General
Transport must be carried out only by those companies with specialist experience, suitable
machinery, equipment and means of transport and properly trained staff. To avoid hazards
for employees and third parties, the relevant accident protection regulations must be
observed.
2.2.2
Preparation for transport
The containers must be prepared for transport so that no damage occurs during loading,
transport and unloading. The loading surface of the transport vehicle must be such 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
forklift is used, the containers must be secured while on the forklift. Connection pieces and
protruding parts of the containers may not be used for lashing or lifting. The containers must
not be dragged over the ground or floor.
2.2.4
Carriage
The containers must be secured against moving around during carriage. The containers
must not be damaged by the mode of fastening used.
2.2.5
Storage
When temporarily stored outside, the containers should be protected from damage and
storms. Containers may not be exposed to the elements for more than 6 months. It must be
absolutely ensured that no rain water or similar substance gets between the interior
container and the collector device.

2.2.6
Damage
For damage caused during transport or interim storage, a competent expert in synthetic
materials should determine the course of action.

General
(1) The containers must be installed under observance of Sections 3 and 4 of the "Special
Provisions" of this National Technical Approval.
(2) In high water or flood areas, the containers must be placed so that they cannot be
reached by the flood.
2
Storage surface
The bottoms of the containers must stand completely on a flat, unbending and smooth slab
or a carefully sealed and secured flat storage surface.
3
Distances
(1) The containers must be placed at such a distance from walls, other components and
each other that at all times the fill level, leaks and status can be visually ascertained. The
marking sign (engraved sign) and the limiting value transmitter (GWG) with connection valve
must be located on a side of the container system that can be accessed. The fill-level
indicator must be easily readable. Moreover, the containers must be placed so that there is a
low risk of explosion and means to extinguish the fire are sufficiently available.
(2) For containers storing heating oil EL grade pursuant to DIN 51603-1 and heating oil EL A
grade Bio 5 to Bio 15 pursuant to DIN V 51603-6, as well as diesel fuel pursuant to DIN EN
590 and DIN EN 14214, the following distances are generally required – when the containers
are filled:
The containers and each container in a container system must have at least 40 cm distance
to the wall on at least one side of the container; the distance to the other walls and to the
other container walls must be at least 5 cm.
4
Setting up
(1) The containers must be installed level at their location. The installation instructions
delivered with the containers (see Section 5.1.4 of the Special Provisions) must be observed.
(2) When setting up container systems, the following requirements must be complied with:
1) The container system must be equipped with a filling system (filling; ventilation and
exhaust; emptying) as described in Sections 1 (4) and 4 (3) and/or 4 (4) of the Special
Provisions.
2) The containers must be set up in a row (a row must not consist of more than 5
containers, the containers must be the same size) or as 2 containers connected on the
front side.
3) The containers must be secured in place with respect to one another by distance
regulators (distance pipes/brackets).
4) The container system must be equipped with a limiting value transmitter that has been
approved for these containers. When installing the limiting value transmitter and non-
connecting emptying system into the filling system specified in Point 1, the reference
values for installation depth specified in the following tables must be complied with.
5) The limiting value transmitter must be installed in the first container (based on the flow
direction when filling) of each container system in compliance with the installation
depth specified for the approved limiting value transmitter.
6) In general, the line used for oil emptying must be a single-line system (without
backflow).

7) The emptying rate must not exceed 17 kg/h (20 litres/h) when using the emptying
system "080/325" produced by the company GOK.

It must be ensured before repeated filling that the fill-level differential among the containers
is not more than 100 mm.
5
Connecting pipelines
When connecting the pipelines to the filling system and/or container nozzles (for single
containers), it must be ensured that nothing is forced and no additional unforeseen external
loads affect the containers. Lines for ventilation and exhaust air must conform to TRbF 20
No. 9.1.2, must be of sufficient dimensions and it must not be possible to block them. They
and their pipe connections must be designed so that they remain sealed at 0.3 bar
overpressure. Several containers may be connected to the same ventilation and exhaust
pipeline only if the liquids they store and their vapours do not combine to produce dangerous
compounds. Ventilation and exhaust lines or systems may not terminate in closed spaces.
Openings must be protected against infiltration by rain water.
