T1 - Odour testing of building products: Examinations for an on-going development of the test standard ISO 16000-28 T2 - Proceedings of healthy buildings 2023 Europe N2 - VOC-emissions and their odours from building products and furnishings present indoors should not have an impact on personal well-being or health. Odours can be measured by applying the standard ISO 16000-28. Indoor air determination of odour emissions from building products using test chambers. One of the described procedures is the assessment of perceived intensity using a comparative scale by a group of panellists. In this paper, the perceived intensity sampling procedure and its evaluation method are investigated and shown to need improvement. New technical developments in the methodology used to increase the reproducibility of measurement results are discussed. Since odour tests are used for labelling, they have a major influence on the assessment of construction products, similar to the procedure of the German Committee for Health Evaluation of Building Products (AgBB). In the original ISO standard, the evaluation is typically performed using a sampling container separated from the emission chamber. For a better sample presentation, an adapter was developed to connect the emission test chamber to the evaluation funnel and thus enable an odour assessment which is comparable to a direct measurement. The investigations show that losses of odourous substances can be greatly reduced, which is very desirable when seeking to obtain reliable results in odour measurement. Another experimental series was carried out to reduce the measurement effort in the evaluation of perceived intensity. Application of the developed greater than or less than/equal to. query could be helpful here. The results show that the query mostly leads to the same result as the evaluation of the perceived intensity using the method according to the standard but is much easier to perform. Overall, the results can contribute to improving the acceptance of the evaluation of perceived intensity using ISO 16000-28 and to determining odours from building materials increasingly more precisely.

T1 - Further Development of Odour Testing of Building Products – Sample Presentation and Evaluation of Perceived Intensity T2 - 17th International Conference HEALTHY BUILDINGS EUROPE 2021 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 - Präzisierung der Geruchsprüfung für Bauprodukte nach DIN ISO 16000-28 – Untersuchung von Vergleichsmaßstäben T2 - Umwelt, Gebäude & Gesundheit: "Neu"- und Altlasten, Innenraumhygiene, Gerüche N2 - Bauprodukte, die in Innenräumen verwendet werden, sollten die Gesundheit und das Wohlbefinden der Personen die sich darin aufhalten nicht durch das Ausdünsten von Geruchsstoffen stören. Die DIN ISO 16000-28 „Bestimmung der Geruchsstoffemissionen aus Bauprodukten mit einer Emissionsprüfkammer“ (DIN ISO 16000-28) beschreibt umfassend die Möglichkeiten der Geruchsprüfung. In Verbindung mit der Anwendung der VDI-Richtlinie 4302 Blatt 1 „Geruchsprüfung von Innenraumluft und Emissionen aus Innenraummaterialien“ (VDI 4302 Blatt 1) ist sie zur Bewertung der empfundenen Intensität von Bauprodukten mit Vergleichsmaßstab geeignet (Umweltbundesamt 2015). In einem vom Umweltbundesamt (UBA) geförderten Forschungsprojekt der Hochschule für Technik und Wirtschaft Berlin (HTW Berlin) und der Bundesanstalt für Materialforschung und –prüfung (BAM) wurden erstmals verschiedene Vergleichsmaßstäbe miteinander verglichen. Ziel des derzeitigen Folgeprojektes ist nun, Mindestanforderungen an Vergleichsmaßstäbe zu erarbeiten, welche die Reproduzierbarkeit der Ergebnisse erhöhen und mit denen die Norm konkretisiert werden kann. Dieser Beitrag stellt die Untersuchungen und Ergebnisse des ersten Projektes und die Schlussfolgerungen für die Durchführung des zweiten Projektes dar. T2 - 12.
