Certificate of conformity
2.4.1
General
(1) The certification that the containers conform to the provisions of this National Technical
Approval must be carried out for each manufacturing site by means of a certificate of
conformity based on internal factory production monitoring, as well as external monitoring on
a regular basis, including an initial inspection of the containers pursuant to the following
provisions.
(2) To obtain the certificate of conformity and the external monitoring, as well as the
associated product inspections, the manufacturer of the containers must make arrangements
with a certification agency recognised for this purpose, as well as a monitoring agency
recognised for this purpose.
(3) The manufacturer must mark the constructed products with the conformity mark,
specifying their use, as a declaration that a certificate of conformity has been issued.
(4) A copy of the certificate of conformity granted by the certification agency must be
submitted by that agency to the Deutsches Institut für Bautechnik. A copy of the initial
inspection report must also be given to the DIBt.
2.4.2
In-house production monitoring
(1) In-house production monitoring must be set up and carried out in each production factory.
In-house factory production monitoring means the continuous monitoring of production by
the manufacturer with the aim of ensuring that the containers produced by the manufacturer
conform to the provisions of this National Technical Approval.
(2) The in-house factory production monitoring must include at least the inspections listed in
Annex 4, Section 1.
(3) The results of in-house factory production monitoring must be recorded and evaluated.
The records must contain at least the following data:
!
Designation of the product and/or the starting material;
!
Type of monitoring or inspection;
!
Date of manufacture and inspection of the product and/or starting material or its
components;
!
Result of monitoring and inspections and comparison with requirements;
!
Signature of the person in charge of in-house factory production monitoring.
(4) The records must be preserved for at least five years and submitted to the external
monitoring agency. They must be submitted to the Deutsches Institut für Bautechnik and to
the most senior competent building monitoring agency if requested.
(5) In the event of unsatisfactory inspection results, the manufacturer must immediately take
the necessary measures to correct the defect. Products that do not meet the requirements
must be handled so that they cannot be confused with compliant products. After the defect
has been corrected, the inspection in question must be immediately repeated, to the extent
technically possible.

No. Z-40.21-432
2.4.3
External monitoring
(1) The in-house production monitoring in each production factory must be verified by an
external body in accordance with Annex 4, Section 2 (2) on a regular basis, however at least
twice annually.
(2) An initial inspection of the containers pursuant to Annex 4, Section 2 (1) must be
performed as part of the external monitoring. Moreover, samples can be taken for random
sample tests. Taking samples and performing inspections are the responsibility of the
recognised monitoring agency. If the usability inspections on which the National Technical
Approval is based are carried out using samples officially taken from ongoing production,
these inspections replace the initial inspection.
(3) The results of the certification and external monitoring must be retained for at least five
years. They must be submitted by the certification agency and/or monitoring agency to the
Deutsches Institut für Bautechnik and to the most senior competent building monitoring
agency, if requested.
3
Provisions for design and measurement
(1) See Section 2.2.4 for behaviour of the containers in a fire.
(2) The conditions for installing the containers are found in the regulations relating to water,
occupational safety and the building code. In this regard, it must be ensured that the
emptying system does not have suction lines that connect with one another. Moreover, the
requirements pursuant to Annex 5 must be observed.
(3) The containers must be protected against impact by vehicles, e.g. by installation in a
protected place, use of collision guards or installation in a suitable area.

tasks within the meaning of § 3 of the Ordinance on Facilities Dealing with Substances
Hazardous to Water of 31 March 2010 (BGBl. I S. 377) unless this type of work has been
excepted from the specialist requirement by state regulations, or the manufacturer of the
containers performs these activities with its own specialist staff.

Provisions for Use, Maintenance, Servicing and Inspection
5.1
Use
5.1.1
Equipping the containers
(1) The conditions for equipping the containers are found in the regulations relating to water,
occupational safety and the building code. If there are no water regulations or building-code
regulations that apply to equipping the containers, Section 9 of TRbF 20
(2) The equipment must be designed to avoid unacceptably high or low pressure and
unacceptable loads on the container wall.
(3) When using the containers as a container system, exclusively a filling system pursuant to
Sections 1 (4) and 4 (3) and/or 4 (4) must be used. In this connection, it must be ensured
that within a container system, only one type of filling system can be used, and that the
diameter of the back pressure nozzle is the same. It is essential that the colours used in the
assembly kit and for the markings are consistent with what is described in the assembly
instructions.
In the event the container system will be expanded at a later time, it must be ensured that
only the same type of filling system, which has been approved for the purpose and has the
same back pressure nozzle diameter, is used. This principle also applies to exchanging parts
of the filling system in an existing system.
(4) In addition to the leakage detector (see Section 2.21.5), each container must be
equipped with a fill-level indicator.
5.1.2
Stored liquids
(1) It is not permitted to store the liquids listed in Section 1(3) when mixed with each other or
with other substances, or if a different liquid has already been stored in the container.
(2) It is not permitted to store contaminated materials if the contaminants would lead to
altered material behaviour.
(3) The substances listed in Section 1 (3) under No. 2 (heating oil EL A grade Bio 5 to Bio 15
pursuant to DIN V 51603-6), No. 3 (diesel fuel pursuant to DIN EN 590) and No. 4 (biodiesel
pursuant to DIN EN 14214) must only be stored in containers equipped with permeation-
resistance. Without the additional documentation pursuant to the foodstuffs regulations
dealing with the material from which the container is made, the plant oils listed in Section 1
(3) under Point 7 must not be used as foodstuffs or to produce foodstuffs.
5.1.3
Usable container volume
The permissible fill proportion of the containers may not exceed 95% if no other fill proportion
has been set out in, or is required by, TRbF 20 No. 9.3.2.2. The limiting value
transmitter/overfill protection system should be set up accordingly [for heating oil EL grade
pursuant to DIN 51603-1 and heating oil EL A grade Bio 15 pursuant to DIN V 51603-6 as
well as diesel fuel pursuant to DIN EN 590 and DIN EN 14214 (biodiesel) see Annex 5,
Section 4 (2)].
