Materials compatibility is a major concern whenever the fuel composition is changed. The aim of this work is to study the interaction of the elastomers: FKM, EPDM, CR, CSM, NBR, IIR, VMQ and FVMQ and biofuels such as biodiesel (FAME), E85 (fuel with 85% ethanol) and B10 (heating oil with 10% biodiesel). Exposure tests were performed with test specimens at 40°C (104°F) and 70°C (158°F) for 84 days to document the changes in mass, volume and tensile properties according to ISO 1817. The exposure tests in E85 showed that the weight gain caused by swelling was in the range up to 12%. The lowest decrease in the tensile properties was determined for FKM, VMQ and IIR. The weight gain of the elastomers in biodiesel varied between 10% (FKM) and 126% (CSM) and the loss of tensile strength between 16% (FKM) and 100% (CSM) at 70°C (158°F). FKM and FVMQ absorbed much less B10 and swelled less. NBR, EPDM, CR, CSM, IIR and VMQ were not resistant to B10 at all as the decrease in the tensile properties was significantly over 50%. Among all of the elastomers FKM showed high compatibility with these biofuels up to 70°C (158°F).

The lack of clarity leads to uncertainties with existential risks and costs for equipment suppliers and operators of dangerous goods vehicles. In order to promote a revision of the supplementary regulations for EX/III vehicles for the transportation of explosive substances and articles of Class 1 in packages, it is therefore necessary to examine the hazards to which explosive substances and articles are exposed during transportation. To this end, existing design solutions will be examined on the basis of current regulations and their effectiveness against a typical external heat load will be determined. The first step is to characterize the heat input by means of calorimeter tests with typical accident loads. Idealized load scenarios are then to be derived from this, which are to be regarded as a prerequisite for standardization work. In the final step, a draft text for the renewal of the existing ADR regulations is to be drawn up and then coordinated internationally.

To obtain approval, these transport packages must adhere to the specification-based criteria of the international transport regulations SSR-6 of the International Atomic Energy Agency (IAEA). To ensure compliance with these requirements, specific mechanical and thermal tests need to be addressed with respect to the package type. Typically, SSR-6 prescribes a mechanical test followed by a thermal fire test as part of different testing scenarios. To approve the latter test of the sequence, BAM performs calorimeter tests in advance with so-called fire reference packages for characterizing the actual fire and its impact on the package to be tested. Packages are designed with different geometry sizes depending on their purpose. For previous tests, the implemented test setups in the fire test stand were sufficiently dimensioned and could cover all requirements in this respect. However, to cover additional testing needs in the future, BAM is expanding the test setup for the purpose of testing significantly larger packages. In previous test setups one ring burner for propane surrounding the test specimen was sufficient. The limiting size in this configuration was the design height of the transport package to be tested. According to the thermal test of the IAEA-Regulations [1], a 30-minute fully engulfing 800°C pool fire or an equally severe fire, e.g., propane gas fire, must be applied to the transport package. Possible adjustments such as nozzle cross-section and propane mass flow can be adjusted to a certain extent. Further modifications, to cover significantly higher and larger packages all-around with a fully engulfing fire, must be accomplished with an additional, second burner ring. Both burner rings had the same dimensions and were mounted on top of each other at different heights to create a significantly larger volume of fire that completely engulfs the package including its impact limiter. To meet the IAEA regulatory boundary conditions, the enhanced fire test stand with the second burner ring is tested with a large fire reference package and will then be used for real-size transport packages after all parameters are successfully met. This fire reference package represents the external geometry of a generic transport cask for radioactive material and is equipped with numerous temperature sensors to record temperature curves at the interior wall surfaces.

Packages for the transportation of radioactive material must demonstrate that the package can withstand certain prescribed tests from the IAEA Regulations [1]. In addition to mechanical tests, a thermal test in form of a fire test must be carried out. As packages to be tested at BAM are signifi-cantly larger than previous package designs, BAM has expanded an existing fire test stand. A modular concept is chosen, which means that the arrangement of the burner nozzles can be adapted to the test specimen. The dimensions of the burner rings, the type, the orientation and the number of burner nozzles can be varied depending on the test specimen. In addition, various pumps can be used to set the corresponding mass flow. With the help of a calorimeter test, the fire test stand can be qualified for a specific size of packages regarding the boundary conditions of the IAEA Regulations [1]. Due to the typically wood filled impact limiters in German package designs, a fire test is necessary, as experiments have shown that possible openings that occurred during a mechanical test contributed to the igni-tion of the wood filled impact limiters within the prescribed 30 minutes of the IAEA Regulations [1]. From a series of experiments, two experiments are pre-sented to show the possibilities to obtain different temperatures and temperature rates in the test specimen. In addition to sensor data, the heat flux into the package is calculated to verify that the IAEA boundary conditions are satisfied. In addition to the temperature data, other data such as wind speed and wind direction are also recorded to explain subsequent effects in the measurement data in a comprehen-sible manner.

By replacing steel with GRP in tanks for gases (propane, etc.) a weight reduction of up to 50 % was reached. In this project not only the material should be optimized, but also the design. Previous tanks consist of a double-walled structure with an insulation layer between the two shells (e.g. vacuum). Goal of this project is to realize a single-walled construction of GRP with an insulation layer on the outside. To determine the temperature dependent material values, two different experiments are performed: In the first experiment, temperature dependent material properties of liquid nitrogen found in literature research are validated in a simple setup. The level of liquid nitrogen in a small jar is measured over the experiment time. Numerical simulation shows the change of nitrogen level with sufficient precision. In the second experiment, a liquid nitrogen is applied on one side of a GRP plate. Temperature is measured with thermocouples on top and bottom of the GRP plate, as well as in the middle of the plate. By use of numerical simulation, temperature dependent thermal conductivity is determined. In the third experiment, a test stand is designed to examine different insulation materials. In this test stand, the insulation material can easily be changed. A numerical simulation, in which the determined material data is used, is performed as well for this test stand. The experiments show, that GRP can be used in cryogenic environments. Multiphase simulations are a suitable tool to describe the energy absorption of thermal energy due to thermal phase change. Results on different insulation materials will follow.

Increasing biofuel use would bring some benefits, such as a reduction in oil demands and greenhouse gas emissions, and an improvement in air quality. Materials compatibility is a major concern whenever the fuel composition is changed in a fuel system. The question arises of whether sealing materials are resistant to fuels with bioethanol and biodiesel (rapeseed oil fatty acid methyl ester). The aim of this work is to study the interaction between sealing materials such as FKM (fluorocarbon rubber), EPDM (ethylene-propylene-diene rubber), CR (chloroprene rubber), CSM (chlorosulfonated polyethylene), NBR (acrylonitrile-butadiene rubber), IIR (butyl rubber), VMQ (methyl-vinyl-silicone rubber), FVMQ (methyl-fluoro-silicone rubber) and PA (polyamide) and biofuels such as biodiesel (FAME, non-aged and 2 years aged), E85 (fuel with 85% ethanol) and B10 (heating oil with 10% biodiesel, non-aged and one year aged) compared with premium-grade fuel at 20°C, 40°C and 70°C for 84 days. Exposure experiments were conducted with specimens of these elastomers to document the changes in the mass and tensile properties of these sealing materials. Visual examination of some test specimens clearly showed a great volume increase until breakage or partial dissolution. The sealing materials FVMQ, VMQ and PA were evaluated as resistant in E85 at 20°C and 40°C with a reduction of tensile properties limited to 15%. None of the examined materials was evaluated as resistant at 70°C with even fluorocarbon rubber losing 20% of its tensile strength in E85. When exposed to biodiesel, elastomers were affected in two ways: firstly, by absorption of liquid by the elastomers and, secondly, by dissolution of soluble components from the elastomers into the liquid medium. Swelling was the result of the high absorption by the elastomers CR, CSM, EPDM, IIR and NBR in comparison to their dis-solution in non-aged and two years aged biodiesel. FKM, VMQ and PA were evaluated as resistant sealing materials in non-aged biodiesel at 40°C. FKM was still resistant in aged biodiesel at 40°C but only to a limited degree at 70°C. The sealing materials CR, CSM, EPDM, IIR, NBR and VMQ were damaged to a high extent in non-aged and one year aged B10 as a result of swelling up to 70°C. FVMQ and PA can be evaluated as resistant in non-aged and one year aged B10 at 20°C and 40°C. However, FKM was evaluated as resistant up to 70°C. The exposure tests showed that all the elastomers tested were resistant in the premium-grade fuel Super at 20°C. On increasing the temperature to 40°C, only FKM, VMQ and PA were resistant to Super. At 70°C FKM showed the best resistance.

Increasing bio-fuel use would bring some benefits, such as a reduction in oil demands and green-house gas emissions, and an improvement in air quality. Materials compatibility is a major concern whenever the fuel composition is changed in a fuel system. The aim of this work is to study the interaction between sealing materials such as FKM (fluorocarbon rubber), EPDM (ethylene-propylene-diene rubber), CR (chloro-prene rubber), CSM (chlorosulfonated polyethylene), NBR (acrylonitrile-butadiene rubber), IIR (butyl rubber), VMQ (methyl-vinyl-silicone rubber) and FVMQ (methyl-fluoro-silicone rubber) and biofuels such as biodiesel, E85 (fuel with 85% ethanol) and B10 (heating oil with 10% biodiesel) at 70°C for 84 days. Experiments were con-ducted with tests specimens of theses elastomers to document the changes in the mass and tensile properties of these sealing materials according to ISO 1817. The exposure tests of the elastomers in E85 at 70°C showed that the weight gain caused by swelling of the test specimens was in the range of 3% to 12%. However, the weight gain of the fluorinated elastomers was at the lower end of this range. Tensile strength and breaking elongation decreased by 22% to 61% or 13% to 77%. The lowest decrease in the tensile properties was determined for FKM, EPDM und IIR. These sealing materials were evaluated as resistant to E85 up to a temperature of 70°C. Biodiesel absorbed water more quickly and aged faster than conventional diesel fuel. The weight loss of the elastomers varied between 9% (FKM) and 126% (CSM) in biodiesel. FKM was evaluated as resistant with a 16% reduction in tensile strength, a 2% reduction in breaking elongation and low weight loss. NBR, EPDM, CSM and VMQ were evaluated as not resistant. CSM even lost 84% of its original tensile strength and 78% of its breaking elongation. The highest weight gain as a result of swelling was measured for CSM with 86%, for EPDM with 84% and for VMQ with 54% in B10, while the fluorine-containing elasto-mers FKM (1%) and FVMQ (3%) absorbed much less B10 and swelled less. FKM lost 23% in tensile strength and 17% in breaking elongation; FMVQ lost 29% in ten-sile strength and 36% in breaking elongation. FMVQ was, therefore, only limited in its resistance to B10. The elastomers NBR, EPDM, CSM and VMQ were not resistant to B10 at all as the decrease in the tensile properties was significantly over 50%. NBR lost about 93% and CSM about 100% of its breaking elongation. The conclusion of the investigations at 70°C is that FKM is the most resistant sealing material in biodiesel, E85 (fuel with 85% ethanol) and B10 (heating oil with 10% biodiesel).

Measurements of the infrared (IR) absorption spectra of microtome slices cut from the walls of jerricans, which were pre-stored with 55% nitric acid for 21 and 42 days at 40°C, showed changes in the structure of the polyethylene. The penetration depths of 55% nitric acid into the polyethylene grades are, in principle, suitable for evaluating the resistance to oxidative degradation of polyethylene grades after pre-storage of the packagings for 21 days. After this period the packaging wall is not fully penetrated. The intensities of the IR bands at 1565 cm-1 (-NO2), 1630 cm-1 (-C=C) and 1654 cm-1 (-O-NO2) increased with the treatment time with 55% nitric acid as a result of oxidative damage by the nitric acid. The high increase in absorbance of the -C=C band in the region 1630 - 1690 cm-1 is attributable to paraffinic chain cracks. The absorbance of the -O-NO2 band, formed as result of the nitration process was still low at a test temperature of 40°C.

Jerricans made of two polyethylene (PE) grades were filled with these fuels and exposed to temperatures of 20°C and 40°C for 1 year. Tensile properties (tensile strength, breaking elongation and elasticity modulus) and melt flow rate (MFR) were determined once a month, and Fourier transform infrared (FTIR) spectroscopy was used to evaluate changes in the chemical structure. Measurements of the MFR and tensile properties of the PE grades after 1 year of exposure to E85 showed only a slightly damaging influence. An increase in the peak of 1585 cm-1 (C=C) stretching vibrations is visible in the FTIR spectra after the immersion tests with E85. Therefore, packagings made of HDPE grades are suitable for the transport of E85. An increase in the MFR with immersion time of the grades in biodiesel was measured, in particular, after 1 year of exposure. The elasticity modulus of the PE grades was reduced with immersion time. The FTIR spectra showed a broadening of the CO peak of 1740 cm-1 and the appearance of the hydroxyl group at 3500 cm-1. Both results are explained by secondary degradation products of the PE decomposition process caused by increasing unsaturated fatty acid content in the biodiesel. In light of the above mentioned, it was concluded that HDPE grades are not suitable as packaging materials for the transport of biodiesel.

These parameters have a relationship with design type tests of packagings for the transport of dangerous goods. This paper presents the results of additional investigations to determine the impact of the pre-storage time of jerricans with 55% nitric acid at 40°C and 23°C on the marginal drop heights in drop tests at –18°C, on the MFR and on the tensile properties. Jerricans made of different polyethylene grades were pre-stored with 55% nitric acid for 21, 42 and 84 days at 40°C and for six months at 23°C. The tests showed that the NIS values at –30°C of polyethylene grades were not comparable with marginal drop heights determined in drop tests at –18°C. Pre-damage with 55% nitric acid for 21 days at 40°C led to an increase in the marginal drop heights of the jerricans. Altering the test regulations by increasing pre-storage time with 55% nitric acid to 42 days would be an alternative. The test results demonstrated clearly that pre-storage of the jerricans for six months at 23°C caused a higher increase in the MFR and lower marginal drop heights for the jerricans when compared with pre-stored jerricans for 21 days at 40°C.

Materials compatibility is a major concern whenever the fuel composition is changed in a fuel System. The aim of this work is to study the interaction between high density polyethylene (HDPE) grades and biofuels such as E85 (fuel with 85 % ethanol) and biodiesel. 10 I jerricans made of two different polyethylene grades were filled with E85 and biodiesel and exposed to temperatures of 20°C and 40°C for one year. Tensile properties (tensile strength, breaking elongation and elasticity modulus) were determined in accordance with EN ISO 527-2 at 23±2 °C once a month, and Fourier Transform Infrared Spectroscopy (FTIR) was used to evaluate possible changes. The tensile properties of HDPE jerrican cuttings decreased, but not significantly, after immersion in E85 and biodiesel. In particular, the elasticity modulus of the polyethylene grades was reduced after exposure to biodiesel. Pin impression tests according to EN ISO 16101 were performed with test specimens of a HDPE grade in White Spirit, E85 and biodiesel. Measurements of the remaining tensile strength showed that biofuels had a stronger effect than White Spirit. The FTIR spectra of HDPE jerrican cuttings showed that immersion tests for one year with E85 at 20°C and 40°C only caused an increase in the peak of 1585 cm'1 (C=C Stretching vibrations) in the Chemical structure of HDPE. The FTIR spectra of HDPE jerrican cuttings showed that immersion tests for one year with biodiesel at 20°C and 40°C led to a broadening of the C=O peak of 1740 cm'1 and the appearance of the hydroxyl group at 3500 cm'1. Both results are explained by secondary degradation products of the polyethylene decomposition process caused by the temperature and unsaturated fatty acid content in the biodiesel since biodiesel decomposes quickly at elevated temperatures. The broadening of the C=O peak to 1740 cm'1 can be attributed to aldehyde carbonyl and ester Carbonyl groups mutually overlapping. Measurements of the melt flow rate (MFR) showed an increase in the MFR with immersion time in biodiesel due to the unsaturated fatty acid formed in the biodiesel. Diffusions of oxygen and rapeseed methyl ester increase the Chemical impact on polyethylene grades.

As the pipeline network is not developed all around the globe, LNG needs to be transported via ship or truck. Double-walled tanks made of steel with a vacuum insulation are currently used to keep LNG at cryogenic temperatures (-162 °C; 111 K). The double-walled construction makes the tanks heavy and expensive. The vacuum insulation between the two walled structure ensures that the LNG stays liquid over the transportation time (boiling point of LNG: -162 ◦C). This causes a high temperature difference between the transported good and the ambient air. Furthermore, there are some restrictions in carrying out in-service inspection using a double-wall design. Therefore, alternative tank designs, such as single wall glass fiber reinforced plastics (GFRP), are of growing interest. The material properties of GFRP and tank insulation at cryogenic temperatures are investigated. Liquified nitrogen (-196 °C; 77 K) is used for all experiments at cryogenic temperatures for safety reasons. Thermal conductivity of different layers are investigated and compared. Mechanical properties are analyzed by performing 3-point bending tests on cooled specimen. When cooled, the specimens fail at a higher force, but all layers of the laminate fail at once. Further investigations into the characterization of material properties, such as CT scans are currently in preparation. Evaluation is done by FEM and in approximation via analytical solutions.

Goal is to design a transportation tank that does not exceed 4 bars (relative) within 10 h, starting at atmospheric pressure. PUR-foam is a suitable material for the insulation. A 12,5 l small scale tank prototype reached 4 bar (relative) within 87 minutes, which is, regarding the influence of the size, a satisfying result. The mechanical properties change significantly at cryogenic temperatures. The bending modulus is similar at first, but decreases at a certain point by appr. 50 %. However, the maximum stress is much higher and could not be reached within this testing setup.

Die Formulierung im entsprechenden Abschnitt des ADR (9.3.4.2) ist nicht eindeutig und verweist auf eine Norm, welche als kritisch angesehen wird. Diese Unklarheiten führen bei den Ausrüstern und Betreibern der Gefahrgutfahrzeuge zu Unsicherheiten mit existenziellen Risiken und Kosten. Es ist hier sowohl aus wirtschaftlicher als auch aus sicherheitstechnischer Sicht vordringlicher Klärungsbedarf erkennbar. Eine Klärung ist zudem dringlich, weil sich auch international bei den beteiligten Akteuren der ADR-Vertragsparteien Fragen zur Klärung der Technologieentwicklung und dem Stand der Technik ergeben haben. Um eine Überarbeitung der ergänzenden Vorschriften für EX/III-Fahrzeuge zur Beförderung von explosiven Stoffen und Gegenständen der Klasse 1 in Versandstücken voranzutreiben, ist deshalb eine Untersuchung der Gefahren erforderlich, denen explosive Stoffe und Gegenstände während der Beförderung ausgesetzt sind. Die beschriebenen Unschärfen der heutigen Vorschriften sollten im Rahmen eines Forschungsvorhabens des Bundesministeriums für Digitales und Verkehr (BMDV) durch eine neuerliche Untersuchung beseitigt werden. Hierzu wurden auf Grundlage der heutigen Vorschriften bestehende konstruktive Lösungen untersucht und deren Wirksamkeit gegenüber einer typischen Wärmebelastung von außen festgestellt. Erforderlich dafür war zunächst die Charakterisierung der Wärmeeinträge durch Versuche mit typischen Unfallbelastungen. Daraus abzuleiten waren dann idealisierte Belastungsszenarien, welche als Voraussetzung für eine Normungsarbeit angesehen werden sollen. Im letzten Schritt soll ein Textentwurf für die Erneuerung der bestehenden Vorschriften des ADR verfasst und im Anschluss international abgestimmt werden. Es soll ein völlig neuer Ansatz zur Auslegung und Bewertung von Bauteilen von EX/III-Fahrzeugen für den Einsatz als Schutzschild gegenüber externer Wärmebelastung gefunden werden. Dieser begründet sich auf neuen technischen Erkenntnissen, welche eine Feuerbelastung heute nicht mehr allein durch eine Einheits-Temperaturkurve (ETK), sondern differenziert nach konvektiven und strahlenden Anteilen betrachtet. Mit ähnlicher technischer Zielrichtung wurde international der neue Standard „Bestimmung der Beständigkeit von Brandschutzmaterialien und -systemen für Druckbehälter gegenüber Kohlenwasserstoffpoolbränden“ als ISO 21843 in Jahr 2018 verabschiedet. Die jeweilige Wärmeleistung bzw. Wärmestromdichte soll mittels Kalorimeterversuchen bestimmt werden. Es gilt den Wärmeeintrag ins Innere der Ladeabteile zu begrenzen. Hierbei stellt sich nicht nur die Frage nach Isolationswirkung sowie Wärmeübergängen und ob dies nur durch Wandung sowie Boden sicherzustellen ist, sondern ob weitere Maßnahmen, wie Reifenschutz, automatische Feuerlöscheinrichtungen, etc. benötigt werden. Letztlich soll durch die Präzisierung der Gefahrgutvorschriften Transparenz bei Anwendern, Zulassungs- und Kontrollbehörden geschaffen werden.

Key achievements include standardised data formats and metadata, a federated repository environment, and improved data visibility and accessibility. Training programs and outreach have significantly increased awareness and adoption of best RDM practices. In the second funding period, the consortium aims to advance these achievements by consolidating this infrastructure, developing a model for its sustainable maintenance and operation, and fostering cultural change for its widespread adoption. Goals include ensuring seamless data workflows from laboratories to open repositories, enhancing interoperability, and supporting innovative research through AI-ready data. The work plan is organised into six task areas (TAs). TA1 (Management) provides leadership and supports all other TAs in achieving their objectives. TA2 (Smart Lab) aims to develop a fully digital research environment, including an ELN as a modular platform. This environment will support data collection, management, storage, analysis, and sharing. Integrating devices and external resources will enable seamless data transfer to repositories. TA3 (Repositories) will consolidate the repository ecosystem. The goal is to integrate repositories into a federated system for better accessibility and interoperability, ensuring long-term data availability and sustainability. TA4 (Metadata, Data Standards, and Publication Standards) focuses on developing and promoting new data and metadata standards in an international community process. This includes applying ontologies to create a semantic foundation for linking research data, making it machine-readable and enabling knowledge graphs. TA5 (Community and Training) is dedicated to fostering a cultural shift towards digital chemistry through continuous engagement, collecting requirements, and providing extensive training and support through workshops and open education resources. It will promote FAIR-compliant machine learning applications, embedding RDM into academic curricula to ensure future scientists are well-versed in these practices. TA6 (Synergies and Cross-Cutting Topics) aims to enhance collaboration across NFDI consortia and beyond. This includes developing ontologies, terminology services, the search service, and other cross-cutting solutions, integrating these developments into existing infrastructure, enabling interdisciplinary data harmonisation and fostering machine learning applications.
