Adsorptive wall materials of four different compositions were exposed to this gas mixture, consisting of 1-pentanol, hexanal, butyl acetate and n-decane. Aim of this study was to scrutinize the ability of these samples to reduce the concentration of the supplied gas. This capacity is expressed in the sorption flux F or area specific adsorption rate respectively. The test was performed referring to a draft of ISO 16000-24.

Dabei stand die Bewertung der Prüfkammermessungen mit Hilfe des AgBB-Schemas im Vordergrund. Dafür wurden die Prüfkammerbedingungen angepasst. Mit Hilfe einer Emissionsdatenbasis wurden Anforderungen an die Emissionen der Umweltzeichenprodukte abgeleitet. Die Datenbasis bildeten vorhandene Emissionsdaten der Umweltzeichenprodukte und Messungen aktueller Produkte. Dazu wurden 10 Prüfkammermessungen an unterschiedlichen Möbelplatten durchgeführt. In Zusammenarbeit mit den Lizenznehmern, dem RAL und dem Umweltbundesamt wurde ein neues Verfahren für die Auswahl der Prüfmuster für die Emissionsmessung erarbeitet. Dieses vereinigt eine repräsentative Auswahl mit einer regelmäßigen Nachprüfung einzelner Möbel und/oder Bauteile. Zudem wurden Kriterien für die Überprüfung der Anforderungen an die Herkunft des Holzes aufgestellt. Für Bodenbeläge, Paneele und Türen aus Holz und Holzwerkstoffen für Innenräume wurde eine neue Vergabegrundlage erschaffen (RAL-UZ 176).

T1 - Reproducibly emitting reference material on thermoplastic polyurethane basis for quality assurance/quality control of emission test chamber measurements N2 - Volatile Organic Compounds (VOC) are ubiquitous in the indoor air since they are emitted from materials used indoors. Investigations of these materials are mostly carried out in emission test chambers under controlled climatic conditions. Reference materials are an important tool for quality assurance/Quality control of emission test chamber measurements but so far they are not commercially available. In this study, a new approach was tested to develop an appropriate reference material with homogenous and reproducible emission of the VOC with well measurable air concentrations in emission test Chambers larger than 20 L at air change rates of 0.5 - 1 /h. Thermoplastic Polyurethane (TPU) was selected as Matrix material which was impregnated with 2,2,4- trimethyl-1,3-pentanediol monoisobutyrate (texanol) as test VOC using compressed carbon dioxide. An optimization of the impregnation parameters such as temperature, pressure, time, VOC injection volume and TPU sample size was performed until the targeted area specific Emission rate (SERa) value was reached. Further aspects like process control, storage effects and correlation of the sample size to the emission rate were investigated. It was found that the SERa immediately after sample preparation were not reproducible between the batches but became unified 10 days after loading into the test chamber indicating the necessity of aging before use. SERa between 13,000 and 18,000 mg m-2 h-1 were obtained, and the impregnated materials could be well stored in aluminum-coated polyethylene foil for at least seven weeks without significant losses. Furthermore, the impregnation of styrene and the SVOC 2,6-diisopropylnaphthalene was tested.

T1 - Reproducibly emitting reference material for quality assurance/quality control of emission test chamber measurements N2 - Volatile Organic Compounds (VOC) are ubiquitous in the indoor air, since they emit from materials used indoors. Investigations of these materials are mostly carried out in test chambers under controlled climatic conditions. Quality control of these test chamber measurements is important but there is a lack of commercially available homogenous reference materials as required for round robin tests or quality assurance of laboratories. The approach of the present study is the impregnation of a supporting material with VOC, which are reproducibly released in measurable chamber air concentrations under standardised test conditions. A polymer made of Thermoplastic Polyurethane (TPU) was chosen as carrier material. It was impregnated with the VOC trimethyl pentanediol isobutyrat (texanol).

A1 - Horn, Wolfgang A1 - Brödner, Doris A1 - Richter, Matthias T1 - Reproducibly emitting reference materials for volatile and semi-volatile organic compounds—using finite element modeling for emission predictions N2 - Recent research into emissions of (semi-)volatile organic compounds [(S)VOC] from solid materials has focused on the development of suitable reference materials for quality assurance/quality control of emission test chamber measurements, which fulfill requirements such as homogenous and reproducible (S)VOC release. The approach of this study was to find a method for preparation of a material with predictable (S)VOC emission rates. AVOC (styrene) and an SVOC (2,6-diisopropylnaphthalene, DIPN), loaded into either vacuum grease or a 1:1 mixture of paraffin/squalane, have been tested. For the prediction of the emission rates, a model using the finite element method (FEM) was created to simulate the (S)VOC emission profiles. Theoretical and experimental results obtained in a Micro-Chamber/Thermal Extractor (μ-CTE™) and in 24 L emission test chamber measurements were in good agreement. Further properties were investigated concerning the material applicability, such as shelf life and inter-laboratory comparability. The maximum relative standard deviation in the inter-laboratory study was found to be 20%.
