T1 - Influence of the length of the internal sleeve valve on the release of powdery substances from the closures of valved bags for dangerous goods N2 - In practice, checks on dangerous goods transports often detect leaks of powdered dangerous goods from valved bags. In this work, the influence factors of a sudden release of powdery substances from the valves of valved bags were investigated. Drop tests were performed on paper bags of UN design type 5M2 with internal sleeve valve using 2 different powdery substances (Esplas H130 and zinc oxide “Rotsiegel”). The internal sleeve valves of all test samples were not sift‐proof with respect to both filling substances. For almost all test samples, the Esplas H130 powder already leaked out of pasted joints during manual filling. This is a contradiction to the requirement in UN 6.1.4.18.1, according to which closures and joints of paper bags 5M2 should be sift‐proof. In the drop tests, longer valve lengths had a greater sealing effect for both filling substances (for filling degrees of at least 95% and for test samples which had already been mechanically loaded). As an extreme example, at the drop height of 1.20 m and a filling degree of 100%, the released amount of zinc oxide powder from a 10‐cm‐long valve was about 16 times higher than from a valve length of 12.5 cm. The valve length is therefore a safety‐relevant parameter and should be specified by the manufacturer. To ensure that only filling goods with similar physical properties in comparison with the test substance are used for valved bags, the user must be informed of the particle size of the test substance.

To prevent subsequent accidents, the European Dangerous Goods Regulations have laid down requirements for testing the chemical compatibility of liquid dangerous goods transported in polyethylene packagings. The test procedures include 6 months in which the chemical is prestored in the packaging. After this time, the respective design-type tests are performed. Alternative methods with so-called standard liquids, simulating the different types of damaging effects, are also possible. If a packaging has successfully passed the design type tests with a standard liquid, other dangerous goods may also be transported in this packaging, as long as it is demonstrated that they have a less damaging effect than the standard liquid. However, in this area there is only little information and research available. A new potentially effective and time-saving method for comparing the stress crack damaging influence of liquids with standard liquids was proposed by a major German chemical company. The validation of this method, which was carried out on two polyethylene materials, showed the general applicability of the method. Two kinds of wetting solutions were applied to simulate cracking under stress. The influence of prestorage, test temperatures, wetting agents and material was examined. FEM calculations were carried out to ascertain the influence of the sample shape.

T1 - Leakproofness of dangerous goods packagings - comparison of worst-case limit leakage rates and sensitivity of the bubble test N2 - This work focuses on the question if the bubble test prescribed in the Dangerous Goods Regulations has sufficient sensitivity to detect leakage rates, which could result in the formation of explosive atmospheres during transport. The sensitivity of the bubble test is not directly comparable with other leak testing methods because of its different flow conditions. Therefore, a normalized minimum detectable leakage rate under Helium test conditions is calculated for the bubble test. This sensitivity of the bubble test under reference conditions is compared with limit leakage rates for a worst‐case transport scenario. The sensitivity of the bubble test is not sufficient to prove the limit leakage rates for 6‐L packagings. The formation of explosive vapour‐air‐mixtures cannot be excluded. Therefore, more sensitive leak testing methods should be considered for smaller packaging design types.

T1 - Staubdichtheit von Säcken und FIBC für feste Gefahrgüter - Eine kritische Betrachtung der derzeitigen Regelsetzung und Transportpraxis N2 - In den internationalen Gefahrgutvorschriften ist vorgeschrieben, dass Säcke und flexible Großpackmittel (Flexible Intermediate Bulk Container – FIBC) staubdicht sein müssen. Eine quantitative Definition des Terminus Staubdichtheit, wie in anderen Technikgebieten üblich, ist jedoch nicht gegeben. Auch geeignete Prüfverfahren zum Nachweis der Staubdichtheit sind in den Vorschriften nicht genannt. In der Praxis der stichpunkartigen Kontrollen von Gefahrguttransporten durch die Schwerlastgruppe der Autobahnpolizei Münster werden immer wieder Austritte von pulverförmigen oder körnigen Gefahrgütern aus eigentlich intakten Säcken und FIBC detektiert. Es wird ein Überblick über die im Jahr 2018 festgestellten Gefahrgutaustritte aus diesen Gefahrgutverpackungen sowie eine systematische Einordnung hinsichtlich betroffener Bauarten und möglicher Ursachen gegeben. Bei der Stofffreisetzung aus intakten Gefahrgutverpackungen liegt ein mechanischer Transport von Partikeln durch Leckkanäle, z. B. im Verschluss-, Naht- oder Wandungsbereich, vor. Generell kommen zwei Freisetzungswege in Frage: Einerseits eine Langzeit-Freisetzung während des Transports, hervorgerufen durch eine kombinierte Wirkung von Stapellast des Füllguts und Transportvibrationen; andererseits eine stoßartige Freisetzung. Auf Grundlage von durchgeführten Untersuchungen hinsichtlich der stoßartigen Freisetzung pulverförmiger Stoffe aus Gefahrgutsäcken werden erste Lösungsansätze hin zu einer Verbesserung der Staubdichtheit von Gefahrgutsäcken und -FIBC vorgestellt. Es wird ein Ausblick auf nachfolgende Arbeiten gegeben. T2 - 48.

T1 - Helium leak testing of dangerous goods packagings N2 - The International Dangerous Goods Regulations prescribe the immersion under water method (“bubble test”) as standard method for the leakproofness test of dangerous goods packagings. But this test procedure acts as a test method for leak localisation, not for quantitative leakage rates measurement. Additionally, the sensitivity in detecting leaks of small diameters is restricted, depending on the test liquid and the test pressure. The bubble test is not suitable for a comparison with quantitative limit leakage rates based on realistic transport conditions. This is especially important when estimating the risk of the formation of an explosive atmosphere during the intercontinental carriage of dangerous goods packagings in freight containers. To compare measured leakage rates with limit leakage rates, a quantitative leak testing procedure is required. Therefore a new approach for dangerous goods packagings is implemented: The pressure technique by accumulation using Helium as a tracer gas. This work presents the test equipment necessary for the quantitative measurement of Helium leakage rates through closures of different kinds of dangerous goods packagings. The essential steps to achieve good repeatable results are: A controlled Helium filling process to reach a defined test pressure in the test sample, a sufficient homogenisation of the Helium-air-mixture inside the test sample and the ensuring of a constant pressure level of the test sample during the test. The Helium loss rate of the accumulation chamber has to be measured separately to receive a correction factor for the measured leakage rates. Different constructional measures are introduced to prevent a disturbing influence of the Helium leakage rate of the filling valves on the measurement results. Methods to estimate the disturbing effect of Helium permeation through permeable parts of the test sample are also presented. As a supporting method for the experimental investigations the Helium sniffer test can be applied. This practical application-oriented advice can enable other users to establish a pressure technique by accumulation for their own technical field.

T1 - Überdruck in Gefahrgutverpackungen unter normalen Beförderungsbedingungen N2 - Für die Durchführung einer Dichtheitsprüfung und für die Bewertung des Ergebnisses ist es wichtig, den sich unter Betriebsbedingungen im Prüfobjekt einstellenden Überdruck zu kennen. Entspricht der Prüfüberdruck nicht dem Betriebsüberdruck, so ist es oft erforderlich, die unter Prüfbedingungen gemessenen Leckageraten auf den realen Betriebsüberdruck umzurechnen. Im Bereich der Gefahrgutverpackungen ist jedoch der spätere maximale Betriebsüberdruck nicht genau bekannt. Er hängt für jede einzelne Verpackungsbauart von dem eingefüllten Füllmedium mit seinen spezifischen Stoffeigenschaften, dem Füllgrad sowie den Beförderungsbedingungen, insbesondere der mittleren Transporttemperatur, ab. Es werden Berechnungsansätze vorgestellt, mit denen sich der Überdruck in Gefahrgutverpackungen unter Beförderungsbedingungen rechnerisch ermitteln lässt. Die theoretisch berechneten Überdrücke werden mit Überdruck-Messwerten verglichen, die mit verschiedenen Füllmedien in unterschiedlichen Verpackungsbauarten ermittelt wurden.
