Sensory analysis - Methodology - Guidelines for the measurement of the performance of a quantitative descriptive sensory panel (ISO 11132:2021)

This document gives guidelines for assessing the overall performance of a quantitative descriptive panel and the performance of each panel member.
This document is applicable to the validation of the training of individual assessors or panels, as well as to the performance monitoring of established panels.
This document does not apply to the panel performance for descriptive methods where the individual scores of each assessor are not recorded, where there is no single list of attributes that is common to all the assessors, or where dominance rather than intensity is measured. Consequently, the performance of descriptive panels using methods such as consensus profile, free-choice profile, flash profile and temporal dominance of sensations (TDS) are out of scope.
The methods specified in this document are for monitoring and assessing the ability of a panel and its assessors to discriminate between products, the agreement between assessors of the same panel and the repeatability of these assessors in their intensity scoring.
Reproducibility, including both the comparison between panels and the comparison within the same panel of several evaluations conducted under different conditions (i.e. separated in time), is out of scope of this document.
The methods specified in this document can be used, in full or a selection only, by the panel leader to appraise continuously the performance of panels or individual assessors. The methods listed are not exhaustive and other appropriate methods can also be used.

Sensorische Analyse - Methodologie - Leitlinien zur Überprüfung der Leistungsfähigkeit eines quantitativ beschreibenden sensorischen Panels (ISO 11132:2021)

Dieses Dokument enthält Leitlinien zur Bewertung der allgemeinen Leistungsfähigkeit eines quantitativ beschreibenden Panels und der Leistungsfähigkeit jedes Panelmitglieds.
Dieses Dokument ist anwendbar auf die Validierung der Schulung einzelner Prüfpersonen oder Panels sowie auf die Überprüfung der Leistungsfähigkeit bestehender Panels.
Dieses Dokument gilt nicht für die Leistungsfähigkeit eines Panels für beschreibende Verfahren, bei denen die einzelnen Punktzahlen jeder Prüfperson nicht aufgezeichnet werden, oder für Fälle, bei denen es keine einzelne Liste mit Merkmalen gibt, die allen Prüfpersonen gemein ist, oder für den Fall, dass eher die Dominanz als die Intensität gemessen wird. Folglich ist die Leistungsfähigkeit von beschreibenden Panels, die Verfahren wie Konsensprofil, freies Auswahlprofil, Flash Profil und zeitliche Dominanz von Empfindungen (TDS, en: temporal dominance of sensations) anwenden,  nicht im Anwendungsbereich erfasst.
Die in diesem Dokument festgelegten Verfahren dienen der Überprüfung und Bewertung der Fähigkeit eines Panels und dessen Prüfpersonen, zwischen Produkten zu unterscheiden, der Übereinstimmung zwischen den Prüfpersonen desselben Panels und der Wiederholbarkeit dieser Prüfpersonen in ihren Intensitätspunktzahlen.
Die Vergleichbarkeit, einschließlich des Vergleiches zwischen Panels und des Vergleiches innerhalb desselben Panels bei verschiedenen Bewertungen, die unter verschiedenen Bedingungen durchgeführt werden (d. h. zeitlich gesondert), liegt nicht im Anwendungsbereich dieses Dokumentes.
Die in diesem Dokument festgelegten Verfahren können im Ganzen oder nur in einer Auswahl durch den Leiter des Panels angewendet werden, um die Leistungsfähigkeit des Panels oder einzelner Prüfpersonen fortlaufend einzuschätzen. Bei den aufgeführten Verfahren handelt es sich nicht um eine vollständige Aufführung und andere geeignete Verfahren können ebenfalls angewendet werden.

Analyse sensorielle - Méthodologie - Lignes directrices pour le mesurage de la performance d'un jury descriptif quantitatif (ISO 11132:2021)

Le présent document donne des lignes directrices pour évaluer la performance globale d’un jury descriptif quantitatif et la performance de chaque membre du jury.
Le présent document est applicable à la validation de l’entraînement des sujets ou des jurys, ainsi qu’au contrôle de la performance des jurys établis.
Le présent document ne s’applique pas à la performance du jury pour les méthodes descriptives dans lesquelles les notes individuelles de chaque sujet ne sont pas enregistrées, dans lesquelles il n’existe pas une liste unique d’attributs communs à tous les sujets, ou dans lesquelles la dominance plutôt que l’intensité est mesurée. Par conséquent, la performance des jurys descriptifs utilisant des méthodes telles que le profil par consensus, le profil libre choix, le profil flash et la dominance temporelle des sensations (DTS) ne fait pas partie du domaine d’application.
Les méthodes spécifiées dans le présent document servent à contrôler et évaluer la capacité d’un jury et de ses sujets à discriminer les produits, l’accord entre les sujets d’un même jury et la répétabilité de ces sujets lorsqu’ils attribuent des notes d’intensité.
La reproductibilité, y compris la comparaison entre jurys et la comparaison au sein d’un même jury, de plusieurs évaluations effectuées sous différentes conditions (c’est-à-dire, séparées dans le temps), ne fait pas partie du domaine d’application du présent document.
Les méthodes spécifiées dans le présent document peuvent être utilisées, en totalité ou en partie, par le responsable du jury pour évaluer de façon continue la performance du jury ou de chaque sujet. Les méthodes énumérées ne sont pas exhaustives et d’autres méthodes appropriées peuvent également être utilisées.
