Lindane, pentachlorophenol, dichlofluanid, tolyfluanid, isodrin, p,p-dichlorodiphenyl trichloroethane and permethrin were the biocides and PCB 28 and PCB 153 were the PCBs studied, all of which are semi volatile organic compounds (SVOC). Their occurrences in the museum environment originate from various sources e.g. preventive treatment of organic exhibits or organic building materials. Exhibits are long-term exposed to these pollutants due to storing in showcases or other storage equipment at low air change rates. To achieve air sampling under the aforementioned conditions the influences of temperature, air circulation, air change rate and relative humidity on the emission behavior of the selected biocides and PCBs had to be determined. This was carried out with pre-soaked wood samples in low volume air sampling experiments using 27 L test showcases and 23 L and 24 L emission test chambers and also diffusive sampling with glass as the sampling material.

In the EU-funded research project H-House more than 30 natural materials (earthen dry boards and plasters, bio-based insulation materials made of wood, flax, reed, straw, etc.) used for renovation and refurbishment were tested regarding emissions of VOC, formaldehyde and radon. Different to ordinary emission tests on single materials this study focuses on the emissions from complete wall assemblies. Therefore, specially designed test chambers were used allowing the compounds to release only from the surface of the material facing indoors. The testing parameters were chosen in order to simulate model room conditions. The emission results were finally evaluated using the AgBB evaluation scheme, a procedure currently applied for the approval of flooring materials in Germany.

T1 - Development of a multi-VOC reference material for quality assurance in materials emission testing JF - Analytical and bioanalytical chemistry N2 - Emission test chamber measurement is necessary to proof building materials as sources of volatile organic compounds (VOCs). The results of such measurements are used to evaluate materials and label them according to their potential to emit harmful substances, polluting indoor air. If only labelled materials were installed indoors, this would improve indoor air quality and prevent negative impacts on human health. Because of the complex testing procedure, reference materials for the quality assurance are mandatory. Currently, there is a lack of such materials because most building products show a broad variation of emissions even within one batch. A previous study indicates lacquers, mixed with volatile organic pollutants, as reproducible emission source for a wide range of substances. In the present study, the curing of the lacquer-VOC mixture inside micro-chambers was optimised. Therefore, the humidity and the chamber flow were varied. Typical indoor air pollutants with a wide range of volatilities, for example, styrene, n-hexadecane, dimethyl and dibutyl phthalate were selected. It turned out that, under optimised curing parameters inside the micro-chamber, their emission can be reproduced with variations of less than 10 %. With this, a next important step towards a reference material for emission testing was achieved.

Workshop - Geruch und Emissionen bei Kunststoffen N2 - The DIN ISO 16000-28 and VDI 4302-1 describe a method for the assessment of the perceived intensity of odours. It is based on a trained assessment panel using a referencing scale that provides defined acetone concentrations. Due to the AgBB-scheme including a place holder for odour assessment it is currently checked whether the method is applicable. To check the applicability a pilot phase regarding the „Implementation of Odour Measurements into the Assessment of Building Products“ was started by AgBB1 in 2012. Düring this phase amongst others two interlaboratory tests were conducted. The first one in 2012 served to test the applicability and to identify need and potential for improvement. Based on those findings an additional Standard Operation procedure was developed for the second interlaboratory test in 2014. The second interlaboratory test confirmed the findings of the first one and the need for improvement of the measurement method as well. Nonetheless both tests showed Standard deviations of reproducibility between 20 and 40%. Standard deviations of reproducibility of well-established interlaboratory tests for VOCs show comparable results. T2 - 17.

Ziel dabei war es, noch bestehende Schwierigkeiten im Umgang mit der Prüfmethode zu identifizieren und Empfehlungen für das weitere Vorgehen herauszuarbeiten.

The resulting measurement values for the perceived intensity were evaluated in consideration of various boundary conditions to identify parameters that could possibly influence the measurement procedure significantly. For the comparison of both interlaboratory comparisons qualified data sets were taken as a basis. Potential for improvement identified in 2012 was mainly confirmed by the interlaboratory test 2014 as well. Besides the accurate conduction as essential part of the measurement it became obvious again that the boundary conditions of the DIN ISO 16000-28 are not defined tight enough. Moreover the thesis that measurements based on the utilisation of comparison scales with only one funnel generate results especially imprecise could not be verified. Both interlaboratory comparisons resulted in relative standard deviations of reproducibility that lay between 20 and 40 % and such are quite comparable with those of well-established interlaboratory VOC comparisons.
