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.

T1 - Environmental and Health Provisions for Building Products - Identification and evaluation of VOC emissions and odour exposure (Research Report 202 62 320 / UBA-FB 001002) N2 - In this study 50 construction products were tested in emission test chambers according to the requirements of the AgBB-scheme: 7 acrylic and 6 silicone sealants, 6 paste-like synthetic resin plasters, 13 wood based products, 4 adhesives, 5 lacquers, 6 wall paints and 3 further construction products. VOC and odour emissions were tested on the 1st, 3rd, 10th, and 28th day. In addition to the VOC-measurements, a test procedure was developed to evaluate odour emission of construction products.This test is planned to be implemented into the AgBB-Scheme. A direct evaluation by a sensory panel in the emission test chamber was not possible. So the odour samples were collected in 300- litre tedlar bags which were evaluated later. Odour intensity of the samples was compared with different acetone concentrations. Within this study an interlaboratory comparison was conducted using the newly developed odour test method. Additionally, VVOC emissions, detection of carcinogenic compounds, repeatability of emission test chamber tests, and other issues are presented. This project has shown that construction products can be evaluated in accordance with the AgBB scheme. A sensory evaluation is intended to be introduced in the AgBB scheme. A method for this evaluation is described in this study. The test procedure should be enhanced and validated for practical utilisation.

A1 - Klingel, R. A1 - Schneider, Uwe A1 - Krocker, Christian T1 - Investigations on radon exhalation of different building materials N2 - The inhalation of 222Rn (radon) is one of the most important reasons for lung cancer, after smoking. Usually, the geological subsoil and the building ground are the dominant sources for enhanced indoor radon levels. Additionally, building materials can increase indoor radon concentrations when these materials contain higher contents of 226Ra (radium), especially in combination with low air exchange rates. For a realistic estimation of indoor radon concentrations, it is helpful to carry out measurements of radon exhalation rates from relevant materials using emission test chambers. In Germany, it is aspired to limit the total indoor radon concentration to 100 Bq/m3, whereby building materials should contribute at most 20 Bq/m3. Within a project financed by the German Institute for Construction Technology (DIBt), a practical oriented measurement procedure of the radon exhalation of building materials in accordance to ISO 16000-9 was developed to have a means for the assessment of these materials with respect to their indoor use. Test chambers with different volumes were used. The tested materials were mainly used for wall constructions (e.g., bricks, light-weight concrete) and have known specific radium activities and radon exhalation rates.

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.

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 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.

Dieses Schema bewertet die mit Hilfe einer Prüfkammermessung bestimmten Emissionen von flüchtigen und schwer flüchtigen organischen Verbindungen (VOC und SVOC). Die Prüfkammer dient dabei der Einhaltung standardisierter Klimabedingungen (Temperatur 23°C, relative Luftfeuchtigkeit 50 %) sowie der Einstellung bestimmter Prüfparameter wie Luftwechselrate und Beladungsfaktor. Die Anforderungen an eine Prüfkammer sind in DIN EN ISO 16000-9 beschrieben. Die Analytik und Quantifizierung der VOC geschieht mittels Tenax-Thermodesorption und nachfolgender Gaschromatographie gekoppelt mit Massenspektrometrie und ist in DIN ISO 16000-6 beschrieben. Probenahmen werden am 3. und 28. Tag der Prüfkammermessung durchgeführt. Am dritten Tag erfolgt eine Bewertung der Emissionen aus dem Bauprodukt anhand des TVOC-Wertes und der Summe der detektierten cancerogenen Stoffe (nach 67/548/EWG, Einstufung als cancerogen der Kategorie 1 und 2). Ein Produkt erfüllt die Kriterien, wenn der TVOC-Wert nach 3 Tagen nicht größer als 10 mg/m³ ist und die Summe der Cancerogene 10 μg/m³ nicht übersteigt. Am 28. Tag wird zusätzlich zum TVOC-Wert und den Cancerogenen die Emission von SVOCs berücksichtigt und eine Einzelstoffbewertung anhand von NIK-Werten vorgenommen. Der TVOC-Wert nach 28 Tagen darf nicht größer als 1 mg/m³ sein, die Summe der Cancerogenen nicht größer als 1 μg/m³. Die Summe an SVOCs darf eine Konzentration von 0,1 mg/m³ nicht überschreiten. Der sogenannte R-Wert, die Summe aller Quotienten aus Einzelstoffkonzentration und dem NIK-Wert des Einzelstoffes, darf einen Wert von 1 nicht übersteigen. Außerdem darf die Summe von Substanzen, die keinen NIK-Wert besitzen, nicht größer als 0,1 mg/m³ sein. Der Ringversuch, der im Rahmen der Untersuchungen zur Verbesserung der Prüfkammermessungen durchgeführt wurde, hatte vor allem den Zweck, den Einfluss unterschiedlicher Methodenparameter bei der Prüfkammermessung in unterschiedlichen Prüflaboratorien zu erfassen. Anhand der Ergebnisse sollte eine Ursachenforschung für die großen Abweichungen der bisher durchgeführten Ringversuche erfolgen. Durch die drei aufeinander aufbauenden Schritte sollte der Einfluss der Analytik, der Probenahme und der Prüfkammer geklärt werden. Der Ringversuch diente nicht der Anerkennung der teilnehmenden Prüflaboratorien im Bereich der Bauproduktenprüfung für eine DIBt-Zulassung. Ausgehend von den Prüflaboratorien, die in der Projektgruppe „Prüf- und Messverfahren zur gesundheitlichen Bewertung von Bauprodukten“ des DIBt mitarbeiteten, wurde der Kreis auf europäische Prüflaboratorien erweitert, die sich ebenfalls mit Prüfkammermessungen an Bauprodukten beschäftigen. Dazu erging ein Einladungsschreiben an alle von vorangegangenen Ringversuchen bekannten Teilnehmer. Insgesamt ergab sich ein Teilnehmerkreis von 29 Instituten, davon 16 aus Deutschland, jeweils zwei aus Österreich, Belgien, Schweden, Dänemark und jeweils eins aus Finnland, Großbritannien, Frankreich, Italien und Portugal. Vor Beginn des Ringversuches waren davon 11 im Zulassungsbereich tätig. Zur wissenschaftlichen Begleitung wurde durch das DIBt ein Betreuergremium einberufen. In zwei Sitzungen (April und November 2007) wurden die aktuellen Ergebnisse vorgestellt und diskutiert sowie die weitere Vorgehensweise besprochen. Eine Abschlussveranstaltung nach der Auswertung des dritten Schrittes des Ringversuches fand im April 2008 im DIBt statt. Dazu waren alle Teilnehmer eingeladen. Für die Emissionsmessung von flüchtigen organischen Verbindungen (VOC) aus Materialien mit Hilfe von Emissionsprüfkammern sind bisher nur wenige Ringversuche durchgeführt worden (De Bortoli et al. 1999; Jann et al. 2000; Hansen et al. 2000; Oppl and Winkels 2002; Windhövel and Oppl 2005; Kirchner 2007; Oppl 2008). Dabei zeigten sich meist große Streuungen der Ergebnisse. Ein großes Problem für die Durchführung solcher Ringversuche ist das Fehlen von Referenzmaterialien mit bekannter Emissionsrate von Zielsubstanzen. Deshalb orientiert man sich für die Auswertung solcher Ringversuche am Mittelwert aller Ergebnisse. Dafür ist die Homogenität des Testmaterials von größter Bedeutung. Diese wurde in früheren Ringversuchen nicht wirklich sichergestellt. Im hier beschriebenen Forschungsprojekt wurde auf die Homogenität des Probenmaterials besonderen Wert gelegt. Der gesamte Ringversuch wurde in drei Schritte unterteilt. Die einzelnen Schritte wurden dabei von Schritt zu Schritt immer komplexer. Im ersten Schritt erfolgte die Analyse von flüssigen Lösungen, im zweiten die Bestimmung von VOCs in Prüfkammerluft und im dritten Schritt erfolgte eine komplette Emissionsprüfkammermessung bei den Teilnehmern. N2 - In the German Institute for Construction Technology’s (DIBt) principles for the health assessment for construction products used in interiors, the Evaluation procedure of the Committee for Health-related Evaluation of Building Products (AgBB Scheme) is contained as a substantial base. This scheme evaluates the emissions of volatile and semivolatile organic compounds (VOC and SVOC), determined by test chamber measurements. Within the interlaboratory comparison, which was divided into three steps, the emission test method from building products was checked against the principles of health-related evaluation of construction products in indoor spaces (based on DIN EN ISO 16000-9 together with DIN ISO 16000-6) with the co-operation of 29 European test institutes. The objective was to assess the comparability of the test method carried out in different test Chambers and using different thermodesorption devices. In the first step the analysis of liquid solutions took place to observe the influence of the analysis itself. In the second step VOCs were sampled in the air of a BAM test chamber onto tubes from the participants for the Analysis by them. In the third step a complete Emission test chamber measurement was carried out by the participants. A major problem for the execution of such interlaboratory comparisons is the lack of reference materials. Therefore the homogeneity of the test material was of great importance. As a result of the first step (analysis of 4 liquid solutions) a standard deviation of less than 20 % for 8 out of 11 substances tested was obtained. The Standard deviations for dichloropropanol, caprolactam and Butyl diglycol ranged up to 36 %. The second step, which included air sampling at a BAM test chamber, resulted in only one standard deviation value less than 20 % (11 % for styrene). The standard deviations for the other six substances were between 20 % and 36 %. For step 3 a sealant was chosen instead of the flooring material for homogeneity reasons. In step 3 the standard deviations for 4 of the 7 measured VOC concentrations from two chamber tests were between 17 % and 19 % and thus within the same range as in Step 1 and even better than for most substances in Step 2. A Standard deviation of 60 % was found for the key component ethanediol, but this can be explained with the difficult analysis method for this substance. A second objective of the project was to formulate criteria against which the specialist competence of the test institutes for emission tests can be checked and based on the principles for the health assessment for construction products used in interior. For this purpose a catalogue of criteria has been developed, which is divided into three parts. In the first part, basic requirements are formulated such as impartiality, accreditation for test chamber measurements, verification of experience by participation in earlier interlaboratory comparisons and the laboratory equipment. The second part requires the test-specific proof in the form of successful participation in interlaboratory comparisons organised by BAM biannually. The third part instructs the laboratories that they must ensure they are always upto-date both in terms of their knowledge and the available equipment. The quality assurance for the knowledge is ensured by regular participation in the exchanging of experience between the test laboratories. In terms of technical requirements the test institutes must be willing to successfully participate in at least one interlaboratory comparison per year. The present interlaboratory comparison was not designed to recognise the participating test laboratories in the field of the construction product testing for a DIBt approval.

T1 - Sensory-based evaluation of building product emissions - Integration into the Blue Angel award criteria and assessment scheme of the Committee for Health Evaluation of Building Products (UBA-FB 001500 / Förder-Kennz. 370762300) N2 - Emissions from building products can considerably impair the quality of indoor air. The AgBB scheme is employed to evaluate the emissions of volatile organic compounds (VOC) from building products. The hygienic evaluation according to the AgBB scheme requires product-specific measuring procedures. These are available for a range of products. They have been validated in co-operation with several research and testing institutes and have been included in the criteria for awarding the Blue Angel ecolabel. The evaluation is, however, stricter and generally has lower limits. VOC emissions and odours can cause health problems so testing using sensors is an important element in the evaluation of building products and has – for reasons of precaution – been set down in the AgBB scheme. The main goal of the project was to derive a method of evaluation using sensors and limits for awarding the Blue Angel and for the AgBB scheme. Based on the research conducted (see Chapter 5 Results and Discussion), perceived intensity and hedonics were suggested as a suitable Evaluation method. The derivation of limits for the evaluation using sensors on the 28th day was effected in the present study through the additional questioning of the test subjects on the reasonability of a sample. For the Blue Angel, there could be different limits of perceived intensity and hedonics for each group of products. A preliminary suggestion for possible limits – for all product groups – is a perceived intensity of 7 pi (5 pi + 2 pi as confidence coefficient, Chapter 5.1.5) and -1 (0+/-0.8, rounded to -1) for the hedonic value.

Hinzu kamen Messungen an 17 im Technikum hergestellten OSB, an denen der Einfluss von Herstellungsparametern auf VOCEmission untersucht wurde. Grundsätzliches Ziel war es, durch die Untersuchungen Lösungsansätze für die Emissionsminderung von VOC aus Holzwerkstoffen zu finden. Dazu wurde auch der Einsatz von Antioxidantien bei der OSB-Herstellung getestet. Die Emissionen des Rohstoffes Kiefernholz wurden an 6 Proben aus Splint- oder Kernholz aus unterschiedlichen Stammabschnitten einer frisch gefällten Kiefer untersucht. Insgesamt konnte mit dem Projekt gezeigt werden, dass einige der im Handel erhältlichen OSB und auch Leimhölzer eine Bewertung nach dem AgBB-Schema aufgrund von zu hohen Aldehyd- und Terpenemissionen nicht bestehen. Für die Aldehydemissionen (insbesondere Hexanal und ungesättigte höhere Aldehyde) konnte durch den Einsatz von Antioxidantien bei der OSB-Herstellung eine Verminderung auf ein Drittel erreicht werden, allerdings stiegen dadurch die Terpenemissionen an. In this project, eight Oriented Strand Boards (OSB) and seven plywood boards from DIY stores were tested in emission test chambers according to the AgBB scheme’s specifications. In addition, 17 OSBs manufactured in a pilot plant were tested to investigate the effect of production parameters on VOC emission. The use of antioxidants in OSB production was also tested. The main objective of the investigation was to find potential solutions for reducing VOC emissions from timber materials. The emissions from pine wood were investigated on six sapwood or heartwood samples from different trunk sections of freshly felled pine. The project’s results show that, due to their high aldehyde and terpene emissions, some types of commercially available OSB and plywood did not meet the AgBB scheme’s requirements. By using antioxidants in OSB production it was possible to reduce aldehyde emissions (especially hexanal and unsaturated higher aldehydes) to one third. However, this caused an increase in terpene emissions.
