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 %.
Das Ziel dieses Kapitels besteht darin, die Rolle von Konformitätsbewertung für die Erhöhung der Cybersicherheit von Produkten, Dienstleistungen und Prozessen zu betrachten. Dazu wird der Begriff Cybersicherheit beleuchtet sowie ausgewählte Cybersicherheitsnormen kurz vorgestellt. Im Folgenden wird der regulative europäische Rahmen für die Konformitätsbewertung aus ordnungspolitischer Sicht sowie der aktuelle Verordnungsentwurf zum Cybersecurity Act dargestellt und kritsch beleuchtet.
This study was designed to examine and compare the operation of accreditation bodies in Europe. A management tool, the Process Maturity Benchmarking Tool (PMBT), was elaborated and validated by applying it to various accreditation bodies. By applying the tool, the values of indicators were determined, thus enabling a comparison of the accreditation bodies despite different operational processes and organizational forms.
The management tool PMBT is based on the analysis of selected processes with high relevance for the operation of accreditation bodies. The processes are derived from a process map designed for accreditation bodies in a universally applicable way. The indicators used to characterize the processes come from two sources: The first source relates to data already available from internal databases, reports, financial audits etc. The second source is derived from a self-evaluation of process maturity performed by the accreditation bodies. The criteria for evaluating process maturity were designed by applying the criteria of the EFQM excellence model 2013 of the European Foundation for Quality Management (EFQM) to the processes identified in the process map.
The project Comparison of the Operation of Accreditation Bodies in Europe comprised three stages. In the first stage, the processes of accreditation bodies were systematically analyzed. A process map was developed and processes of special relevance for the performance of accreditation bodies were identified and underpinned by indicators as described above. In the second stage, the processes of the German accreditation body DAkkS were assigned to the tool. This stage was used to check and modify the indicators when necessary. In the third stage, the transferability of the model was analyzed by extension to seven other accreditation bodies operating in Europe. The third stage of the project ended with a workshop attended by the eight accreditation bodies, which was used to present and discuss the results of the comparison and to identify best practices.
Extraction, chromatographic separation, and quantification of low-concentration organic compounds in complex matrices are core challenges for reference material producers and providers of calibration services. Evidence of successful participation in formal, relevant international comparisons is needed to document measurement capability claims made by national metrology institutes (NMIs) and designated institutes (DIs). To enable NMIs and DIs to update or establish their claims, in 2014 the Organic Analysis Working Group (OAWG) initiated CCQM-K95.1 "Low-Polarity Analytes in a Botanical Matrix: Polycyclic Aromatic Hydrocarbons (PAHs) in Tea". This was a follow-on comparison from CCQM-K95 which was completed in 2014.
The polycyclic aromatic hydrocarbons (PAHs) benz[a]anthracene (BaA) and benzo[a]pyrene (BaP) are considered priority pollutants by U.S. Environmental Protection Agency and are regulated contaminants in food, pose chromatographic separation challenges, and for which exist well-characterized measurement procedures and standard materials. BaA and BaP in a smoked tea were therefore selected as representative target measurands for CCQM-K95.1. Ten NMIs participated in CCQM-K95.1. The consensus summary mass fractions for the two PAHs are in the range of (50 to 70) ng/g with relative standard deviations of (6 to 10) %.
Successful participation in CCQM K95.1 demonstrates the following measurement capabilities in determining mass fraction of organic compounds, with molar mass of 100 g/mol to 500 g/mol and having polarity pKow −2, in a botanical matrix ranging in mass fraction from 10 ng/g to 1000 ng/g: (1) value assignment of primary reference standards (if in-house purity assessment carried out), (2) value assignment of single and/or multi-component organic solutions, (3) extraction of analytes of interest from the matrix, (4) cleanup and separation of analytes of interest from interfering matrix or extract components, and (5) separation and quantification using gas chromatography or liquid chromatography.
Solutions of organic analytes of known mass fraction are typically used to calibrate the measurement processes used to determine these compounds in matrix samples. Appropriate value assignments and uncertainty calculations for calibration solutions are critical for accurate measurements. Evidence of successful participation in formal, relevant international comparisons is needed to document measurement capability claims (CMCs) made by national metrology institutes (NMIs) and designated institutes (DIs). To enable NMIs and DIs to update or establish their claims, in 2015 the Organic Analysis Working Group (OAWG) sponsored CCQM-K131 "Low-Polarity Analytes in a Multicomponent Organic Solution: Polycyclic Aromatic Hydrocarbons (PAHs) in Acetonitrile".
Polycyclic aromatic hydrocarbons (PAHs) result from combustion sources and are ubiquitous in environmental samples. The PAH congeners, benz[a]anthracene (BaA), benzo[a]pyrene (BaP), and naphthalene (Nap) were selected as the target analytes for CCQM-K131. These targets span the volatility range of PAHs found in environmental samples and include potentially problematic chromatographic separations. Nineteen NMIs participated in CCQM-K131. The consensus summary mass fractions for the three PAHs are in the range of (5 to 25) μg/g with relative standard deviations of (2.5 to 3.5) %.
Successful participation in CCQM-K131 demonstrates the following measurement capabilities in determining mass fraction of organic compounds of moderate to insignificant volatility, molar mass of 100 g/mol up to 500 g/mol, and polarity pKow < −2 in a multicomponent organic solution ranging in mass fraction from 100 ng/g to 100 μg/g: (1) value assignment of primary reference standards (if in-house purity assessment carried out), (2) value assignment of single and/or multi-component organic solutions, and (3) separation and quantification using gas chromatography or liquid chromatography.
Elektro"älter"geräte
(2018)
Seit September 2015 gelten für neue Heizgeräte EU-weit einheitliche Mindeststandards: Heizkessel müssen mindestens den Standard der Brennwerttechnik erreichen (ausgenommen sind B1-Gasetagenheizungen für Mehrfachbelegung). Wird ein alter Wärmeerzeuger ausgetauscht, muss daher stets der Schornstein für die Abgasabführung im Überdruck geeignet sein und gegen Kondensat ertüchtigt werden, also feuchtebeständig sein. Handelt es sich um eine mehrfach belegte Abgasanlage der Arten C4, C8 oder B3, sind alle am Schornsteinstrang angeschlossenen Gasgeräte betroffen. In einem Expertengremium des DVGW wurden Handlungsempfehlungen erarbeitet. Einige Lösungsansätze vermeiden einen sofortigen Austausch aller Geräte an einem gemeinsamen Schornsteinstrang.

Die Ressourcen der Erde sind nicht nur endlich, sondern werden zudem ineffizient genutzt. Mit dem im Dezember 2015 verabschiedeten Aktionsplan zur Kreislaufwirtschaft fördert die Europäische Kommission den Übergang zur stärker kreislauforientierten Wirtschaft. So werden Anforderungen an Reparaturfähigkeit, Lebensdauer und Recyclingfähigkeit von Produkten zukünftig in der Ökodesign-Richtlinie gesetzt. Die Ökodesign-Richtlinie regelt momentan die Energieeffizienz von energieverbrauchsrelevanten Produkten. Um Anforderungen an den nachhaltigen Einsatz von Ressourcen zu formulieren, fehlen jedoch Normen und Definitionen. Diese Normen werden Momentan geschaffen - erst danach können gesetzliche Anforderungen folgerichtig umgesetzt werden.
The adsorption of water in one-dimensional channels in porous aluminophosphate material AlPO4-5 has been studied by a combination of gravimetric Analysis techniques, neutron and X-ray diffraction and Neutron spectroscopy. Molecular structure of AlPO4-5 consists of 12-membered rings of alternating, corner-sharing AlO4 and PO4 tetrahedra connected by oxygen bridges into sheets in the (a, b) plane. The sheets are connected by oxygen bridges along the c crystal axis and form onedimensional channels of which the largest, formed by the 12-membered rings, have a van der Waals Diameter of about 8.3 Å. Gradually increasing the amount of adsorbed water we could follow the evolution of the confined water mobility in a systematic way and identify the molecular mechanism of water adsorption. We focused particularly on the range of low and medium relative pressures up to p/p0=0.32, where a Change from a hydrophobic behavior to a steep, capillary condensation like water intake has been observed. At the Initial adsorption stages water occupies positions close to the pore walls causing the contraction of channels in the (a, b) plane and the prolongation of the channels along c axis in AlPO4-5. With the progressing intake water molecules form chains along the main channels. The cooperative interactions between water molecules lead to the onset of phonon-like cooperative modes and, surprisingly, to the increase of diffusive-like motion, which slow down only in the final adsorption stages when AlPO4-5 channels are completely filled.
Standardization research is a fairly new and is a still-evolving field of research, with possibly major practical ramifications. This article presents a summary of the authors’ subjective views of the most pressing research topics in the field. These include, among others, standards (e.g. incorporation of ethical issues), the potential impact of standards, the corporate management of standardization and legal issues like Intellectual Property Rights (IPR). In addition, gaps have been identified with a respect to a basic understanding of standardization, suggesting a need for better education in the field.
Currently BAM is making efforts to recode COMAR, the database for CRMs and reshape its profile as a database intended for qualitatively top-of-the-market CRMs. These efforts are highlighted and placed into the broad perspective of the international RM markets. A link to EPTIS, the database for PT schemes as a blueprint for the recoding is provided.
COMAR, where do you go?

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?
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.

Neues Energielabel
(2018)
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.
