Die Kreislaufwirtschaftsinitiative der Europäischen Kommission fordert klar grundlegende Aspekte der Kreislaufwirtschaft in bereits bestehende Rechtsrahmen einzubetten. Anforderungen zur gesetzlich vorgeschriebenen Lebensdauer, Reparierbarkeit und Recyclingfähigkeit von Produkten sollen zukünftig auf europäischer Ebene ins Leben gerufen werden. Ein geeignetes Spielfeld ist die Ökodesign-Richtlinie. Momentan regelt sie primär die Energieeffizienz von energieverbrauchsrelevanten Produkten, doch der Fokus wird aktuell um Anforderungen an den nachhaltigen Einsatz von Ressourcen erweitert. Bei den gegenwärtigen Aktivitäten im Ökodesign steht der Normungsauftrag M/543 im Zentrum. Es wurde 2015 von der Europäischen Kommission an CEN/CENELEC vergeben und später stieß auch ETSI dazu. Bislang sind acht generische EN-Normen und zwei Fachberichte (Technical Report (TR)) geplant. Sie sollen grundlegende Aspekte der Nachhaltigkeit von energieverbrauchsrelevanten Produkten, die von der Ökodesign-Richtlinie betroffen sind, abdecken. Trotz der zu erwartenden hohen Reichweite dieses Vorhabens scheinen die Inhalte und der eigentliche Zweck der zu erarbeitenden Normen vielen Marktakteuren noch nicht vollständig bekannt zu sein. Daher hat ein nationaler Zentralverband eingeladen zu berichten. In dem Vortrag werden Antworten auf folgende Fragen gegeben: Warum im Ökodesign? Was ist geplant? Was ist betroffen? Worum geht es in den Normen?

In this study, the test method EN 14825 for testing air conditioners is validated by verifying the sensitivity of the seasonal energy efficiency ratio SEER (declared on the energy efficiency label) in relation to the nominal cooling capacity Pdesign. Therefore, the two major parts of the test method, the measurement part and the calculation part, were investigated. Measurements were conducted on several single-split units. The calculation part was subjected to a sensitivity analysis in order to identify the properties of an air conditioner which have a strong influence on the SEER. The analysis revealed that the measurement procedure delivers reproducible results. However, the energy consumption in special operating states, the duration in active-mode and seasonal performance values in active mode (SEERon) significantly affect the sensitivity of the SEER. Especially assumption of short operating times for a cooling active mode leads to large changes in the SEER with varying Pdesign. In addition, the range of power of Pdesign turned out to have an increasing impact on the SEER with decreasing Pdesign. For Pdesign values ≤10 kW, which is the most popular type of ACs in the EU, the sensitivity of the SEER increases tremendously.
Especially the determination of the SEER for devices with short operating times in cooling active-mode (350 h) and low values for Pdesign (≤10 kW) cannot be reproduced anymore. In consequence, manufacturer could use the sensitivity of the SEER on Pdesign to artificially “increase” the energy efficiency of their air conditioner for the Energy label about 10 %.
Digital transformation and especially the dramatic rise of products and services connected to the Internet of Things raise the questions on how to deal with the increasing risks related to Privacy and Cybersecurity. Presumably, these risks seem to be insufficiently reflected in the European Union’s current regulative system – by being neither part of the traditional definition of a safe product nor part of product-specific vertical or horizontal directives. Certification based on standards as underlying requirements has been identified by policymakers as an instrument to address this issue. The latest European draft regulation aims at increasing security and trust in ICT products and services, and reducing current European market fragmentation with a new Cybersecurity Certification Framework. Based on the results of a qualitative analysis of stakeholder statements on the current proposal on the Cybersecurity Act, this paper discusses elements of the proposed Cybersecurity Certification Framework. As a theoretical background, this paper provides definitions of the terms Safety, IT-security, and Cybersecurity, presents selected Cybersecurity-related standards and provides an outlook on future challenges to Conformity Assessment in the digital transformation.

Standardization for the Industrial Internet of Things: Engagement by China, Germany and the USA
(2018)
Standardization is a major challenge for a successful digital transformation of manufacturing. Industry and governments have put this topic on their agenda and stakeholders worldwide are engaged in various Standard Development Organizations, consortia and fora, seeking to shape the standards for the Industrial Internet of Things (IIoT). This paper for the first time analyzes how well participants from the USA, China and Germany are actually represented and engaged in standards development for the IIoT. Using quantitative metrics, the study specifically investigates standardization activities for Wireless Sensor Networks at the Internet Engineering Taskforce (IETF). The results are divergent: Measuring the authorships of IETF Internet-Drafts, China’s successful catch-up in international standardization is confirmed, having even outperformed the USA. When it comes to the authorship of the actual standards at IETF, China could not assert its top position. Here, US authors are leading, followed by German participants. The paper discusses different engagement patterns in depth and analyzes the national economic, institutional and political backgrounds that influence them.

Several models of range hoods were tested by independent and accredited testing institutes. The results have been compared to the information declared by the manufacturer on the energy efficiency label and the product fiche. The measured electric power input of the lighting System and the measured grease absorption factor often differed significantly from the declared values.
The reasons for these observations and the necessary steps to ensure accurate measurements and a meaningful EU energy efficiency label are elucidated. It is suggested that the ranges of the lighting efficiency classes are readjusted to fit the nowadays prevalent LED technology.
Furthermore the tolerance in the regulation for the nominal electric power input of the lighting could be extended by a minimum absolute tolerance. The grease absorption test method may need a rework to achieve a satisfying accuracy.
The energy label is a tool that informs the consumer about the energy consumption of certain appliances. The tumble dryer is one of these appliances that were considered relevant for receiving an energy label in the European Union. All classes and values on the energy label are stated by the manufacturers. In order to guarantee that the manufacturers do not cheat and appliances are labeled correctly, the stated values are checked by the market surveillance of each country in compliance verification tests. However, in the case of tumble dryers these compliance verification tests are very expensive and can only be realized for a small sample size out of models which are available on the market. The fewer compliance verification tests are carried out, the higher is the chance that there are incorrectly labeled appliances on the market. Therefore, a modification of the test standard for tumble dryers has been analyzed which would reduce the costs of a performance test by at least 11 %.
