Klappentext: Die Anforderungen der DIN 10503 verstehen und umsetzen! Als eine der ältesten Normen aus der DIN 10500 Reihe "Lebensmittelhygiene" diente die DIN 10503 im Ursprung als Sammlung verschiedener hygienerelevanter Begriffe. Der ständige Fortschritt im Bereich der Lebensmittelsicherheit und der weitere Vorstoß von Standards in der Branche erforderte eine grundlegende Überarbeitung der Normenreihe. So ist Anhang A neu aufgestellt als Kapitel zur Lebensmittelsicherheit und beinhaltet die Themen HACCP, DIN 22000 und Bekanntmachung der EU Kommission. Die Begriffsgruppen sind sortiert und geben nun auch Einsteigern ein übersichtliches Werkzeug an die Hand und erleichtern die Normungsarbeit. Die Anhänge B und C liefern Ihnen normative und informative Inhalte zur Gestaltung von Flussdiagrammen. Verwenden Sie diese, um Ihre internen Verfahrensanweisungen anzupassen und auch dort der Norm zu entsprechen. Die Kommentierung der Anforderungen und Aktualisierungen beschreiben die Hintergründe der DIN 10503:2022-03 und helfen, Begrifflichkeiten zu verstehen, Anforderungen richtig zu interpretieren und rechtssicher zu handeln.

International audience ; Increasing fuel prizes, future CO2 emission legislation as well as new powertrain architectures are the main factors for truck manufacturers to invest into fuel saving technologies. Especially for long haul heavy duty transport and high mean engine loads, Rankine cycle waste heat recovery can lead to significant fuel savings. In this study transient road cycle simulations are performed to compare different Rankine architectures, coupled to a mild hybrid driveline, using tailpipe heat as heat source and ethanol as working fluid. The results show better performance for the indirect cooling strategy. Furthermore the multi-model proportional integral controller is considered as the best controller to fulfill the requirements about safety and performance.

Driven by future emissions legislations and increase in fuel prices engine, gas heat recovering has recently attracted a lot of interest. In the past few years, a high number of studies have shown the interest of energy recovery Rankine based systems for heavy duty trucks engine compounding. Recent studies have brought a significant potential for such a system in a Heavy Duty (HD) vehicle, which can lead to a decrease in fuel consumption of about 5% [Wang et al. (2011)] and reduce engine emissions. But many challenges still need to be faced before the vehicle integration. This paper presents a control strategy development for waste heat recovery Rankine based systems in heavy duty trucks. Due to the highly transient operating conditions, improving the control strategy of those systems is an important step to their integration into a vehicle. It is shown here that moving to more advanced control strategies than classical PIDs lead to some gains in terms of performance. Due to the limited availability and high operational cost of test bench, the validation of such a controller is done on a representative and previously validated model. ; Peer reviewed
