Milk - Quantitative determination of microbiological quality - Guidance for establishing and verifying a conversion relationship between results of an alternative method and anchor method results (ISO 21187:2021)

This document gives guidelines for the establishment of a conversion relationship between the results of an alternative method and an anchor method, and its verification for the quantitative determination of the microbiological quality of milk.
NOTE     The conversion relationship can be used a) to convert results from an alternative method to the anchor basis or b) to convert results/limits, expressed on an anchor basis, to results in units of an alternative method.

Milch - Quantitative Bestimmung der mikrobiologischen Qualität - Leitfaden für die Erarbeitung und Verifizierung einer Übertragungsbeziehung zwischen den Ergebnissen von einem alternativen und einem Bezugsverfahren (ISO 21187:2021)

Dieses Dokument gibt Anweisungen für die Erarbeitung einer Übertragungsbeziehung zwischen den Ergebnissen eines alternativen und eines Bezugsverfahrens sowie für deren Verifizierung für die quantitative Bestimmung der mikrobiologischen Qualität von Milch.
ANMERKUNG   Die Übertragungsbeziehung kann a) zur Übertragung von Ergebnissen von einem alternativen Verfahren auf die Bezugsbasis oder b) zur Übertragung von Ergebnissen/Grenzwerten, ausgedrückt auf einer Bezugsbasis, in Ergebnisse in Einheiten eines alternativen Verfahrens verwendet werden.

Lait - Mesure quantitative de la qualité microbiologique - Lignes directrices pour établir et vérifier une relation de conversion entre les résultats de la méthode alternatif et les résultats de la méthode d’ancrage (ISO 21187:2021)

Le présent document donne des lignes directrices pour l'établissement d'une relation de conversion entre les résultats d'une méthode alternative et les résultats d'une méthode d'ancrage, et sa vérification en vue de la détermination quantitative de la qualité microbiologique du lait.
NOTE       La relation de conversion peut être utilisée a) pour convertir les résultats d'une méthode alternative sur la base de la méthode d'ancrage ou b) pour convertir les résultats/limites exprimés sur la base de la méthode d'ancrage, en résultats exprimés dans les unités d'une méthode alternative.
