TY - GEN A1 - Hahn, Oliver A1 - Wilke, Olaf A1 - Jann, Oliver T1 - Characterization of air quality in museum show cases N2 - The present study comprises the characterisation of museum show cases concerning their hazardous potential for art objects. In order to estimate potential risks of damage the emission of volatile organic compounds coming from several construction materials is monitored and different air exchange rates from exhibit cases are determined. For the determination of the VOCs different methods were applied. The first step is a direct thermal extraction of the materials followed by emission test chamber measurements. The tracer gas method with N2O that is used in this study is a convenient procedure to investigate air exchange rates under working conditions greater than 0.05 d-1. The results of this study confirm the importance of the careful choice concerning building materials for show cases. Furthermore the analyses clarify that certain organic compounds might be a problem for the exhibits in show cases with low air exchange rates.

Against the backdrop of a public debate about possible hazards related to these emissions, ⁠UBA⁠ has commissioned BAM to develop a measurement method for these emissions, to expand the existing awarding criteria for the "Blue Angel" ecolabel by the aspect of particle emissions and to physically and chemically analyse particulate emissions. The resulting awarding criteria will be submitted to RAL later this year. ⁠Emission⁠ characteristics of laser printing devices, conclusions on awarding criteria and interim results of the project were discussed in three sessions of a project-related expert group.

For these VVOC so-called LCI values (lowest concentration of interest) were derived which are used for the calculation of the so-called R-value (risk index, see reference 1 for the calculation). Test chamber measurements of particle boards show that the emissions of VVOC might have significant impact on the R-value and therefore for the health evaluation.

(Salthammer, 2014) In Germany this will change because the latest version of the German AgBB scheme for health evaluation (2015) now include VVOC, e.g. ethyl acetate and ethanol. In this study selected compounds were tested with the procedure described in ISO 16017 and a method for measuring VVOC with thermal desorption was developed. Three different adsorbents Tenax TA, Carbograph 5TD and Carbopack X were tested to analyse VVOC according to ISO 16017. For the tested VVOC, Carbograph 5TD showed the best results under the chosen analytical conditions.

Foam tiles made from melamine resins are often used for acoustic insulation because they show good fire resistance and good thermal insulation properties. But they can emit formaldehyde. In Germany there are cases with a resulting indoor air concentration of higher than 100 µg/m³. In this study samples from two schools and one office were investigated. Additionally, new tiles were purchased and tested to evaluate the general potential as formaldehyde source.

The amounts of volatile organic compounds (VOC) which emit from products in emission test Chambers are used to evaluate these products. Typically labelling procedures for construction products are based on emission test chamber measurements. This performance should be verified. Possibly this can be performed due to testing of one material at different laboratories within a round robin test. Therefore it is necessary that a reference material exists which can be used for such round robin tests or as part of the quality management System to ensure comparable results. The different Statistical evaluation possibilities of a round robin test with a constant reference material for VOCs (volatile organic compounds) in emission test Chambers are the main focus of the presented paper.
