Air quality - Determination of odour concentration by dynamic olfactometry
This European Standard (EN) defines a method for the objective determination of the odour concentration of a gaseous sample using dynamic olfactometry with human assessors and the emission rate of odours emanating from point sources, area sources with outward flow and area sources without outward flow. The primary application is to provide a common basis for evaluation of odorant emissions in the member states of the European Union.
Luftbeschaffenheit - Bestimmung der Geruchsstoffkonzentration mit dynamischer Olfaktometrie
Diese Europäische Norm legt ein Verfahren fest zur objektiven Bestimmung der Geruchsstoffkonzentration einer gasförmigen Probe durch Anwendung der dynamischen Olfaktometrie mit Personen als Prüfern und zur Bestimmung der Emissionsströme von Geruchsstoffen aus Punktquellen, Flächenquellen mit definiertem Volumenstrom und Flächenquellen ohne definierten Volumenstrom. Das Hauptziel ist die Schaffung einer gemeinsamen Grundlage zur Bewertung von Geruchsstoffemissionen in den Mitgliedstaaten der Europäischen Union.
Der Geltungsbereich dieser Norm bezieht sich auf die Messung von Geruchsstoffkonzentrationen reiner Substanzen, definierter Gemische und nicht definierter Gemische gasförmiger Geruchsstoffe in Luft oder Stickstoff mit dynamischer Olfaktometrie, wobei ein Panel mit Personen als Prüfern die Funktion von Sensoren übernimmt. Die Messeinheit ist die Europäische Geruchseinheit pro Kubikmeter [GEE/m³]. Die Geruchsstoffkonzentration wird durch Bestimmung des Verdünnungsfaktors gemessen, der zum Erreichen der Wahrnehmungsschwelle erforderlich ist. Die Geruchsstoffkonzentration an der Wahrnehmungsschwelle beträgt per Definition 1 GEE/m³. Die Geruchsstoffkonzentration wird dann als Vielfaches der Wahrnehmungsschwelle ausgedrückt. Der Messbereich liegt üblicherweise zwischen 101 und 107 GEE/m³ (einschließlich Vorverdünnung).
Diese Europäische Norm gilt für:
- Messen der Massenkonzentration reiner Geruchsstoffe an der Wahrnehmungsschwelle in g/m³;
- Messen der Geruchsstoffkonzentration von Geruchsstoffgemischen in GEE/m³;
- Messen der Emissionsrate von Geruchsstoffemissionen aus Punktquellen und Flächenquellen (mit und ohne definierten Volumenstrom), einschließlich Vorverdünnung während der Probenahme;
- Probenahme von Geruchsstoffen aus Emissionen mit hoher Feuchte und Temperatur (bis 200 °C);
- Feststellen der Wirksamkeit von Abgasreinigungseinrichtungen, die zur Reduzierung der Geruchsstoffemissionen verwendet werden.

Qualité de l'air - Détermination de la concentration d'une odeur par olfactométrie dynamique
La présente Norme européenne définit une méthode pour déterminer de façon objective la concentration d'odeur d'un échantillon gazeux par olfactométrie dynamique avec des sujets humains ainsi que le taux d'émission d'odeurs émanant de sources ponctuelles, de sources superficielles avec écoulement vers l'extérieur et de sources superficielles sans écoulement vers l'extérieur. La première application est de fournir une base commune pour l'évaluation des émissions odorantes dans les États membres de l'Union Européenne.
Le domaine d'application de la présente Norme européenne est la mesure de la concentration d'odeur de substances pures, de mélanges définis et de mélanges non définis d'odorants gazeux dans l'air ou l'azote, en utilisant l'olfactométrie dynamique avec un jury de sujets humains comme détecteurs. L'unité de mesure est l'unité d'odeur européenne par mètre cube ouE/m3. La concentration d'odeur se mesure en déterminant le facteur de dilution requis pour atteindre le seuil de détection. La concentration d'odeur au seuil de détection est par définition de 1 ouE/m3. La concentration d'odeur s'exprime ensuite en termes de multiples du seuil de détection. L'étendue de mesure va en général de 101 ouE/m3 à 107 ouE/m3 (y compris la prédilution).
Le domaine d'application de la présente Norme européenne comprend :
¾ la mesure de la concentration massique au seuil de détection des substances odorantes pures, en grammes par mètre cube ;
¾ la mesure de la concentration de l'odeur des mélanges de substances odorantes, en ouE/m3 ;
¾ la mesure du taux d'émission des émissions odorantes depuis des sources ponctuelles et des sources superficielles (avec ou sans écoulement extérieur), y compris la prédilution pendant le prélèvement ;
¾ le prélèvement de substances odorantes à partir d'émissions avec une humidité et une température élevées (jusqu'à 200 °C) ;
¾ la détermination de l'efficacité des dispositifs de rejet utilisés pour réduire les émissions d'odeurs.

Steven’s Law describes the a-linearrelation between odour stimulus and its perceived intensity. When using odour concentrations in dispersion modelling, the issueis complicated by the effects of the averaging time of the dispersion model, further complicating the use of the odourconcentration as a direct measure for dose. To define a ‘no nuisance level’, the entire method of dosage evaluation, includingthe dispersion model, will yield a ‘dose’. The relation between this ‘dose’ and its effect (odour annoyance) should be validated inpractical situations to be a useful predictive tool for occurrence of odour nuisance.3.1.47odour detectionto become aware of the sensation resulting from adequate stimulation of the olfactory system3.1.48odour panelsee panelSIST EN 13725:2003
