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.

Luftprobenahme und Analytik erfolgten für VOC mittels Tenax TA und anschließender Thermodesorption (TDS) in Verbindung mit GC / MS. Ozon wurde kontinuierlich bestimmt. Der Ozonanalysator arbeitete auf der Grundlage der flammenlosen Reaktion von Ozon mit Ethylen nach dem Prinzip der Chemilumineszenz. Die Staubbestimmung erfolgte gravimetrisch mittels Glasfaserfilter und Ultramikrowaage. Zusätzlich wurde die Partikelemission während des Druckbetriebes mit einem Partikelzähler bestimmt. Aufgrund der technischen Rahmenbedingungen standen nur kurze Druckzeiten von maximal 36 Minuten zur Verfügung. Um die Gleichgewichtskonzentration in der Prüfkammer zu erreichen, wurde die Luftaustauschrate in den 1 m³ - Kammern auf n = 4,0 bis 4,7 pro Stunde erhöht. Zusätzlich zur Prüfung in den Emissionsmesskammern sind verschiedene Papiere mittels Direkt - TDS sowie unter- schiedliche Toner mittels Headspaceprobenahme in Kombination mit GC / MS hinsichtlich ihres Emissionsverhaltens untersucht worden. Für die untersuchten Geräte wurden Emissionsraten ermittelt. Sie betrugen für TVOC 0,41 bis 22,4 mg pro Stück und Stunde, für Ozon kleiner 0,02 bis 4,6 mg pro Stück und Stunde sowie für Staub 0,10 bis 7,63 mg pro Stück und Stunde. Verglichen mit Frischfaserpapier wurden bei den Untersuchungen mit Recyclingpapier deutlich höhere SVOC - Konzentrationen nachgewiesen. Im Ergebnis der Untersuchungen wurde ein Prüfverfahren entwickelt, das die Basis für Emissionsmessungen im Rahmen der Umweltzeichen RAL –UZ 62, RAL –UZ 85 sowie des neuen RAL –UZ 114 für Multifunktionsgeräte darstellt. Abstract The emission behaviour with regard to dust, ozone and VOC (TVOC) of nine different hardcopy devices in combination with suitable air sampling and analysis procedures was investigated in different emission test chambers (two different 1 m³ - chambers and one 20 m³ - chamber). Air sampling and analysis for VOC were done by means of Tenax TA and subsequent thermal desorption (TDS) in connection with GC / MS. Ozone was determined continuously. The ozone analyser worked on the basis of the flame rid reaction of ozone with ethylene according to the principle of chemiluminescence. The dust determination was done gravimetrically by means of glass fibre filter and an ultra micro - balance. Additional the particle emission during the printing process was measured with a particle counter. The general technical conditions of the tested hardcopy devices were the reason for short printing times with a maximum of 36 minutes. In order to achieve the equilibrium concentration in the test chambers the air exchange rate in the 1 m³ - test chambers had to be increased to a value of n = 4,0 to 4,7 per hour. Additional to the examination of the hardcopy devices in the emission test chambers different papers were investi- gated by means of direct - TDS and different toners were tested by means of head space sampling in combination with GC / MS. For the examined hardcopy devices emission rates were determined. The emission rates for TVOC ranged from 0,41 to 22,4 mg per piece and hour, for ozone from less than 0,02 to 4,6 mg per piece and hour and for dust from 0,10 to 7,63 mg per piece and hour. The comparison between recycling paper and paper produced from primary fibres showed in general higher SVOC emissions from recycling paper. As the result of the investigations a test method for the determination of emissions from hardcopy devices was developed. This test method is the basis for emission tests in the framework of the German Award of the Environmental Label for office devices RAL -UZ 62, RAL -UZ 85 and the new RAL -UZ 114 for multifunctional devices.

In the requirements limits were set for ozone, dust and styrene emissions. The former test methods did no longer correspond to today’s requirements with regard to emission measurements. In addition, the emission behaviour of hardcopy devices due to the use of different and non-com parable test methods has been recently discussed controversely. For this reason a new test method had to be developed which enables a reliable, reproducible determination of emission rates (ER) for dust, ozone and VOC (volatile organic compounds). The basis for this was the ECMA-Standard 328 compiled by ECMA (European Computer Manufacturer Association) using dynamic chamber measurements. Nine different machines, desktop laser printers as well as office devices like bigger copiers and multifunctional devices were investigated. As a result of the study new criteria for the Blauer Engel for copiers, printers and a new created for multifunctional devices, concerning TVOC, ozone and dust emission were determined. Additionally a model is presented calculating the concentrations in real rooms under usual printing conditions derived from the test chamber results.

In this system pure liquid substances are kept separately at a constant temperature, evaporated according to their vapour pressure and removed by a small inert gas flow. A modular set-up allows flexible handling. All vapours generated are finally united in a mixing chamber. Any concentration level of the gas mixture can be produced by a suitable combination of evaporation temperature, carrier and dilution gas flows. Test results from continuous operation over six weeks are presented. The equipment was tested on seven volatile organic compounds (VOC) of different vapour pressure ranges. It was possible to establish stable operation for the equipment during the entire period and reproducible gas concentrations which were traceable to the mass as an SI unit, thus the system is suitable for long-term tests.--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Im Beitrag wird die Entwicklung eines Gasmischsystems (GMS) beschrieben, das die dynamische und rückführbare Generierung von langzeitstabilen VOC-Gasgemischen im ppb-Bereich erlaubt. Dabei werden Reinsubstanzen separat temperiert, ihrem Dampfdruck entsprechend verdampft und durch einen kleinen Inertgasstrom abgeführt. In einer Mischkammer werden sie schließlich zusammengeführt. Durch die Kombination von Verdampfungstemperatur, Träger- und Verdünnungsgasflüssen ist die Einstellung eines beliebigen Konzentrationsniveaus des Gasgemischs möglich. Aus einem Dauerbetrieb von sechs Wochen werden Untersuchungsergebnisse gezeigt. Dabei wurde die Apparatur mit insgesamt sieben flüchtigen organischen Verbindungen (VOC) unterschiedlicher Dampfdruckbereiche betrieben. Die Anlage lief über den gesamten Zeitraum stabil und lieferte reproduzierbare und auf die Masse als SI-Einheit rückführbare Gaskonzentrationen. Somit ist das Verfahren für Langzeitanwendungen geeignet.

Besides scenarios with varying loading factors, air exchange rates and climatic conditions were investigated to evaluate the formaldehyde emission potential of different building products. Under realistic indoor conditions used for the emission chamber tests, exceeding of formaldehyde indoor guide values were obtained. Results showed the need for improvement of wood-based materials with lower formaldehyde emissions and the adaption of testing parameters closer to realistic conditions.

A1 - Wilke, Olaf A1 - Jann, Oliver T1 - Application of a novel reference material in an international round robin test on material emissions testing JF - Indoor Air N2 - Emission testing of products is currently a rapidly increasing field of measurement activity. Labelling procedures for construction products are based on such emission test chamber measurements and hence measurement performance should be verified. A suited procedure for this purpose is the testing of one unique homogenous material in different laboratories within a Round Robin Test (RRT). Therefore, it is useful to have a reference material which can be used within inter-laboratory studies or as part of the quality management system to ensure comparable results. Several approaches on the development of reproducibly emitting materials have been published. These have in common only to emit a single VOC – toluene. Two further research studies carried out by BAM aimed to develop reference material for emissions testing containing one or more VOC in a single material. The first approach was a doped lacquer with Volatile and Semi-Volatile Organic Compounds (VOC/SVOC) and the second was Thermoplastic Polyurethane (TPU) or a Squalane/Paraffin mixture. Results received with the lacquer based material were presented in more detail.

In 2017 EN 16516 (Construction products - Assess-ment of release of dangerous substances - Determination of emissions into indoor air) was published as a new harmonised standard for the emission testing of construction products. Because test chamber conditions are different, both standards give different concentrations for formaldehyde. To determine a conversion factor four test series were set up with different wooden boards. For a loading of 1 m²/m³ the conversion factor is 1.6. This means that the formaldehyde concentration measured under the conditions of EN 16516 is a factor of 1.6 higher compared to EN 717-1.

To ensure the comparability of results from different testing laboratories, their measurement performance must be verified. For this purpose, Bundesanstalt für Materialforschung und -prüfung (BAM) organizes an international proficiency test (round robin test, RRT) every two years using well-characterized test materials (one sealant, one furniture board, and four times a lacquer) with defined VOC emissions. The materials fulfilled the requirements of homogeneity, reproducibility, and stability. Altogether, 36 VOCs were included of which 33 gave test chamber air concentrations between 13 and 83 µg/m3. This is the typical concentration range to be expected and to be quantified when performing chamber tests. Three compounds had higher concentrations between 326 and 1105 µg/m3. In this paper, the relative standard deviations (RSD) of BAM round robin tests since 2008 are compared and the improvement of the comparability of the emission chamber testing is shown by the decrease of the mean RSD down to 28 % in 2018. In contrast, the first large European interlaboratory comparison in 1999 showed a mean RSD of 51 %.

The aim of this study is to develop a method for the measurement of these organic compounds, which generally have low or moderate vapor pressures. The biocides considered in this study are permethrin, dichlofluanid, tolylfluanid, iodpropinylbutylcarbamat, octylisothiazolinone, tebuconazole and propiconazole. The emission from two commercial products (plastic foil, wool carpet) containing biocides and of seven types of biocidal formulations applied to wood or clay tiles were investigated in 20-l glass emission test chambers. Each chamber test was performed over a period of 100–200 days, and one investigation was conducted over several years. Compared to volatile organic compounds, low-volatility compounds show totally different emission curves in chamber tests; maximal emission values may be reached in days or weeks. A period of 3 months is sometimes necessary for the determination of area-specific emission rates (SERa's). The SERa's (?g m-2 h-1) from biocide-containing products were determined for permethrin (0.006), propiconazole (0.3), dichlofluanid (2.0), tolylfluanid (1.0), octylisothiazolinone (2.5) and iodpropinylbutylcarbamat (2). In most cases, the SERa stayed at its maximum value or declined slowly over the test period. Additionally, a chamber test begun in 1994 with a piece of wood treated with a typical mixture of biocides dissolved in a technical solvent was continued. SERa's (?g m-2 h-1) for dichlofluanid (0.20), tebuconazole (0.49) and permethrin (0.08) remained detectable after the period of nearly 9 years during which the sample remained continuously in the chamber. This test proved the very slow decrease of emission of low-volatility compounds like permethrin and tebuconazole.

T1 - Biocide emissions from materials into indoor air T2 - Indoor air 2002 N2 - The European biocides directive (98/8/EG) demand the control of emissions into the envi-ronment like soil, water and air. In this study a method for measuring the input of biocides into the indoor air from materials should be developed. The emission of two products containing biocides (plastic foil, wool carpet) and six different types of biocide containing formulations applied on wood or ceramic tiles were investigated in 20 or 23 l glass emission chambers. Each chamber test was performed over a period of 100 up to 200 days. SVOC show totally different emission curves in chamber tests compared to volatile organic com-pounds (VOC). They reach their maximum value after some days or weeks. Thus a period of 3 months is sometimes necessary for exact measurements. Area specific emission rates (SERa in µg/m²h) for permethrin (0.006), propiconazole (0.2), dichlofluanid (1.5), tolylfluanid (1.2), octylisothiazolinone (2.5) and for iodpropinylbutyl-carbamat (1.7) were determined.

Single components were tested in comparison to three complete structures (same concrete, primer, screed, adhesive) with different types of floor covering (PVC, carpet, linoleum). Sorption into concrete/screed and different sealing by the flooring materials affected the emissions from the complete structures. The complete structures with linoleum and PVC showed the same emissions and emission rates as the flooring materials alone. Emissions from the carpet-covered structure resulted mainly from the lower layers. For two adhesives the formation of secondary emissions (aldehydes and organic acids) was observed starting after the standard testing time of 28 days.

Based on an inter-laboratory study with many German, European and US-American laboratories an extemal quality assurance System for the analysis of VOC emitting from products or the measurement in indoor air should be implemented (financed by the German Federal Environmental Agency). A focus was set on the emission test chamber experiments and the connected analytical procedure. VOC have a dominating influence when applying the German AgBB scheme for health evaluation of building products. Therefore it is necessary to ensure that the results between the testing laboratories are comparable. The successful participation to such round robin tests is offen essential for the acceptance of results given by an analytical laboratory.
