T1 - Methoden zur Differenzierung von Tierarten in Lebensmitteln – Status quo N2 - Nicht zuletzt bedingt durch den Pferdefleischskandal im Jahr 2013 wurden in Deutschland die Aktivitäten bei der Methodenstandardisierung im Bereich der Tierarten-Differenzierung in den vergangenen Jahren intensiviert. Wenn auch positive Befunde bei dem Nachweis von Bestandteilen aus Pferd in Lebensmitteln wie Lasagne derzeit so gut wie nicht mehr anzutreffen sind, so hat die Tierartendifferenzierung insgesamt beim Nachweis von Verfälschungen in Lebensmitteln einen hohen Stellenwert. Diese Arbeit fasst daher den aktuellen Stand der Analytik in Deutschland mit Schwerpunkt bei der Standardisierung zusammen. Sie wurde erstellt durch die Arbeitsgruppe „Biochemische und molekularbiologische Analytik“ der Lebensmittelchemischen Gesellschaft mit Unterstützung von Experten der Arbeitsgruppe „Molekularbiologische Methoden zur Pflanzen- und Tierartendifferenzierung“ (§ 64 LFGB) sowie der ALTS-Arbeitsgruppe „Immunologie und Molekularbiologie“ (jeweils D).

T1 - Versailles Project on Advanced Materials and Standards interlaboratory study on intensity calibration for x-ray photoelectron spectroscopy instruments using low-density polyethylene N2 - We report the results of a Versailles Project on Advanced Materials and Standards interlaboratory study on the intensity scale calibration of x-ray photoelectron spectrometers using low-density polyethylene (LDPE) as an alternative material to gold, silver, and copper. An improved set of LDPE reference spectra, corrected for different instrument geometries using a quartz-monochromated Al Kα x-ray source, was developed using data provided by participants in this study. Using these new reference spectra, a transmission function was calculated for each dataset that participants provided. When compared to a similar calibration procedure using the NPL reference spectra for gold, the LDPE intensity calibration method achieves an absolute offset of ∼3.0% and a systematic deviation of ±6.5% on average across all participants. For spectra recorded at high pass energies (≥90 eV), values of absolute offset and systematic deviation are ∼5.8% and ±5.7%, respectively, whereas for spectra collected at lower pass energies (<90 eV), values of absolute offset and systematic deviation are ∼4.9% and ±8.8%, respectively; low pass energy spectra perform worse than the global average, in terms of systematic deviations, due to diminished count rates and signal-to-noise ratio. Differences in absolute offset are attributed to the surface roughness of the LDPE induced by sample preparation. We further assess the usability of LDPE as a secondary reference material and comment on its performance in the presence of issues such as variable dark noise, x-ray warm up times, inaccuracy at low count rates, and underlying spectrometer problems. In response to participant feedback and the results of the study, we provide an updated LDPE intensity calibration protocol to address the issues highlighted in the interlaboratory study. We also comment on the lack of implementation of a consistent and traceable intensity calibration method across the community of x-ray photoelectron spectroscopy (XPS) users and, therefore, propose a route to achieving this with the assistance of instrument manufacturers, metrology laboratories, and experts leading to an international standard for XPS intensity scale calibration.

T1 - Building codes and standards in earth building - current situation in Germany N2 - Today, building is a complicated commercial process characterised by legalised agreements between all participants. For commercial building projects, all materials and constructions have to conform to building standards and regulations. Material properties must be reproducible in standardised test procedures. This also applies for the control of the quality of production of earth building materials and constructions. Building conservation is a part of this process. Generally, national building standards have to reflect the current situation of building materials / construction systems of that country for which they have been developed.

T1 - The new German standards for earth blocks and earth masonry mortar N2 - In August 2013, the German National Institute for Standardization DIN published three national standards for industrially-produced earth building materials without the use of chemical stabilizers: DIN 18945 Earth blocks – definitions, building materials, requirements, test procedures DIN 18946 Earth masonry mortars – definitions, building materials, requirements, test procedures DIN 18947 Earth plaster mortars – definitions, building materials, requirements, test procedures The development of these standards was initiated by the Dachverband Lehm e.V. (DVL), the German umbrella organisation for building with earth. These standards are in accordance with the requirements of the EU Regulation No. 305/2011 which came into force in Germany on 1 July 2013. These basic requirements introduce provisions relating not only to the safety of buildings and other construction works but also to health, durability, energy economy, protection of the environment and other important aspects in the public interest. The basic requirements are defined by essential characteristics expressed by levels or classes, or in a description. The relevant essential characteristics define the performance of the construction product. The DIN 18945, 46 and 47 outline unified test procedures describing the relevant essential characteristics of the earth building products as well as systems for assessing and verifying the constancy of their performance. The relevant systems of verification are determined by a national Technical Assessment Body (TAB), which in Germany is the Deutsches Institut für Bautechnik DIBt.
