T1 - Weiterentwicklung des Geruchsmessverfahrens für Bauprodukte (Teil II): Anwendung eines Adapters und vereinfachtes Bewertungsverfahren T1 - Further Development of the Odour Measurement Method for Building Products (Part II) N2 - Zur Weiterentwicklung der Probenpräsentation wurde ein Adapter entwickelt, der Emissionsprüfkammer und Bewertungstrichter miteinander verbindet und dadurch eine der direkten Messung vergleichbare Geruchsbewertung ermöglicht. Die analytischen Messungen zeigen, dass es kaum Unterschiede in der Zusammensetzung der Probenluft in der Kammer im Vergleich zum Probenbehälter gibt. Bei den olfaktorischen Messungen kam es jedoch bei der Bewertung der Probenluft mit Hilfe des Adapters zu Minderbefunden. Anschließende Untersuchungen zeigten, dass beim Ausschalten des Geräts Umgebungsluft über den Trichter in den Adapter strömt und zu einer Verdünnung der Probenluft führt. Um dies zu vermeiden, werden derzeit weitere Messungen durchgeführt. Eine weitere Versuchsreihe wurde durchgeführt, um den Messaufwand bei der Bewertung der empfundenen Intensität zu reduzieren. Die entwickelte „größer-oder-kleiner/gleich“ Abfrage kann hier hilfreich sein. Die Untersuchungen im Luftqualitätslabor und im Rahmen eines Ringversuches mit verschiedenen Laboren, zeigen, dass die Abfrage in fast allen Fällen zu den gleichen Ergebnissen führt, wie die normgerechte aber aufwendigere Ermittlung der empfundenen Intensität mithilfe des Vergleichsmaßstabes. N2 - For technical improvement of sample presentation an adapter was developed to connect the emission test chamber with the evaluation funnel and thus enabling a more direct measurement. The analytical measurements demonstrate that the air has a very similar composition sampled at the funnel or in the emission test chamber. The results of the olfactory measurements show overall that the intensities determined using the adapter are often reported as lower. Further investigations have shown that air backflow via the funnel into the sample container of the adapter may be the cause. This has to be avoided in future. Another experimental series was carried out to reduce the measurement effort of evaluation of perceived intensity. Here application of the developed ‘greater than, or less than/equal to’ survey could be helpful. The results of the measurements in the air quality lab and in the frame of a round robin test indicate, that the survey leads to the same evaluation as the more complex determination of perceived intensity with standard method.

T1 - Entwicklungen der Bewertungsmethodik von Gerüchen in Innenräumen N2 - Um eine gute Luftqualität in Gebäuden zu erreichen, müssen Reinigungslasten durch Lüften aus Räumen abgeführt bzw. vermieden oder verringert werden. Wird der Luftwechsel verringert, verschlechtert sich die Raumluftqualität, und die Zufriedenheit der Nutzer nimmt ab. An Arbeitsplätzen kann es bei schlechter Luftqualität und der daraus resultierenden Unzufriedenheit zu einer geringeren Produktivität der Beschäftigten kommen. Um die Reinigungslasten und deren Wirkung auf den Raumnutzer überdas Geruchsempfinden zu verringern, ist neben einer messtechnischen Erfassung der Verunreinigungen auch eine sensorische Prüfung in Innenräumen und von Bauprodukten notwendig. In diesem Artikel wird die Entwicklung der Bewertungsmethodik von Gerüchen im Innenraum erläutert und auf Anwendungen eingegangen.

T1 - VOC emissions from building materials accompanying sensory tests for different evaluation schemes N2 - Within a follow up project of a former study (Horn et al. 2005) emissions and odor from different types of construction products were investigated (financed by the German Federal Environmental Agency - FKZ 37 07 62 300). The tested materials were mainly those used for construction of floors indoors. For this type of materials in Germany several labeling procedures exist which are based on Emission chamber testing. Two important labeling procedures in Germany are based on the AgBBevaluation scheme (Däumling et al. 2005). For some applications (flooring material) it is the mandatory Ü-mark of DIBt (German Institute for Construction Technology). Furthermore for carpets, adhesives and many other products, like sealants, mattresses, furniture and so on the voluntary blue angel mark exist. Within this scheme the volatile organic compounds (VOC) compounds are measured with well established procedures and are evaluated with LCI-values which were derived from health information. Beyond that many complaints according to building products are caused by odors. Therefore an evaluation procedure for the odor is very important and should be implemented into all of the mentioned labeling schemes.

T1 - Results of sensory tests and sensory-limit settings for building materials in Germany N2 - Indoor air pollutants influence the health and comfort of building occupants and consequently the energy consumption of the building. The pollutants are emitted by various sources. Among these sources, building products are of particular importance. To control the emission of pollutants from building materials, a few different voluntary labelling Systems have been introduced in Europe. In Germany also mandatory “Principles for the health assessment of construction products used in interiors” have been applied for the technical approval of floor coverings since 2004. This procedure is based on the assessment scheine of the Committee for Health-related Evaluation of Building Products (AgBBScheme). The sensory-limit settings for building-material label Blue Angel offer consumer to differ not only low-emission but also low-odour Building materials from another building materials.

Intensive und unangenehme Gerüche werden von Bewohnerinnen, Bewohnern und Angestellten nicht akzeptiert und können auf Dauer krank machen. Bislang stand noch kein allgemein anerkanntes Messverfahren zur Verfügung. Dieses wurde nun in Forschungsprojekten entwickelt, wobei auch konkrete Bewertungsvorschläge zur Zumutbarkeit von Gerüchen gemacht wurden. Das Verfahren ist an die Messung der Emissionen flüchtiger organischer Verbindungen aus Bauprodukten gekoppelt und nutzt Probanden, um die Geruchsstärke (Intensität) und den Geruchseindruck (Hedonik) zu ermitteln. In der Praxis wird das Verfahren nun an verschiedenen Stellen erprobt. Die Bewertung der Geruchsemissionen gibt der Industrie die Möglichkeit, geruchsarme Produkte zu gestalten. Die Kennzeichnung geruchsarmer Bauprodukte mit dem Umweltzeichen Blauer Engel erleichtert Verbraucherinnen und Verbrauchern die Orientierung beim Einkauf. N2 - Measuring and evaluating odour emissions from building products used in indoor spaces are becoming increasingly important for the construction of energy-efficient buildings. Intensive and unpleasant smells are not accepted by inhabitants and employees and may lead to negative health effects. Up to now a consistent measuring method for odour emissions has not been available. A measuring method and also concrete standards for the assessment of odours by using reasonableness of smells have now been developed in succeeding research projects. The procedure uses a panel of test persons to determine the strength (intensity) and impression (hedonic appraisal) of odour and is linked to the already well established measurement of the emission of volatile organic compounds from building products. At the Moment the new procedure is tested in practice at different laboratories. Evaluating odour emissions helps manufacturers to develop products with low or very low odour emissions. The labeling of low-odour Building products with the environmental label Blue Angel gives consumers an orientation for purchase.

T1 - Further Development of Odour Testing of Building Products – Sample Presentation and Evaluation of Perceived Intensity N2 - Indoor air quality is affected by the emission of volatile organic compounds (VOC) or the odour from building products. Odours can be measured by applying the standard ISO 16000-28:2020. In the study presented here proposals for further technical development of the ISO method are presented. The sampling procedure and evaluation method of the perceived intensity are investigated in particular because they have a major influence on reproducibility of measurement results.

T1 - New developments in odour testing: Adapter connects emission test chamber and funnel N2 - Healthy and energy efficient buildings must be free from disturbing odours. Odour emissions from building materials can be measured with the well-known and accepted standard ISO 16000-28 “Indoor air – Part 28: Determination of odour emissions from building products using test chambers”. For commonly used emission test chambers the sample air is collected in containers (bags) and presented to a group of panel members for the purpose of evaluating the odour. A standard sets requirements for the on-demand presentation in detail. These include the validation procedure for container materials, pre-treatment of bags, details on storage of filled bags and how to carry out the measurements. However, although these measures are proven in practice, incorrect measurements are still possible. Also errors can occur due to a very complex measurement procedure. So, there is a great need for research into how the odour samples are presented. The proposal planned to be presented will introduce a new development in sample provision by using an adapter which enables collection and provision of sample air without storage or transport of bags. The adapter is a sample container which is permanently positioned on the emission test chamber´s outlet and continuously filled with sample air flowing through it. The flow is briefly interrupted at the time when a sample is taken by a panel member for the test. The size of the container is sufficient to provide enough sample air for evaluation by at least one panel member via a funnel. Since sampling and presentation are technically connected, it means you can almost do away with storage or transportation and thus it can be presented almost unchanged to the panelmembers. The aim is to reduce measurement errors in the odour samples provision process and the improvement of measurement reproducibility. The paper presents the construction of the adapter as well as the results of emission and odour tests carried out so far.
