N2 - The question, what is a suitable diluent for the group of desensitized explosives, is adressed in this presentation. After a review of the definions from the corresponding regulations a possible testing scheme is presented and discussed. It should only be possible to test a phlegmatized explosive out of class 1 via a negative result in test series 6. The characteristics of a suitable diluent is discussed in the second part of the presentation.

Im Bereich Biomasse als erneuerbarer Energieträger wird besonders Holz ein großes Wachstum auf dem Energiesektor prognostiziert (NITSCH 2007). Die Speicherung dieser Energie erfolgt meist durch Holzhackschnitzelhalden in der Umwelt. Um ein tieferes Verständnis der in der Halde ablaufenden mikrobiologischen Prozesse erhalten zu können, wurden in einer neu aufgebauten Kiefernholzhackschnitzelhalde mit den Ausmaßen 15 m x 20 m x 6 m folgende Messungen durchgeführt: a.) Messung der Gaskonzentration von Sauerstoff, Kohlendioxid als auch der Temperaturentwicklung innerhalb der Halde; b.) Messung der Veränderung der Holzzusammensetzung innerhalb der Halde über die Zeit; c.) Charakterisierung der Veränderung der Zusammensetzung der bakteriellen als auch der pilzlichen Lebensgemeinschaften über die Zeit; d.) Charakterisierung von dominanten Vertretern der bakteriellen als auch der pilzlichen Lebensgemeinschaften. Die Ergebnisse zeigen, dass sich die Funktion und die Zusammensetzung der Lebensgemeinschaften über die Dauer der Holzhackschnitzellagerung ändern, und dass diese Änderungen nur zum Teil mit den Prozessen bei Kompostierungsanlagen vergleichbar sind.

This model includes the heat production from chemical, physical and microbial exothermal processes. In the manuscript the laboratory experiments needed to develop and validate the model are described. In addition, temperature and gas concentrations were measured in two large-scale wood piles (volumes bigger than 1000 m³), in order to provide the applicability of the model to large-scale scenarios. The predictions of the model and the large-scale experimental data showed good agreement concerning the maximum temperature reached inside an open air wood pile. Special attention has been devoted to the microbial processes, since they proved to be the most important cause of heat production in the early stages of storage. This work is intended to help in predicting and thus avoiding possible self-ignition scenarios for this type of wood storage.
