Soil improvers and growing media - Sample preparation - Part 2: Sample preparation for microbiological examination
This document specifies the general requirements for the preparation of samples and initial suspensions prior to microbiological examinations of soil improvers and growing media. This method is intended especially for sample preparation prior to microbiological examinations of e.g. E. coli, Salmonella spp. and Enterococcaceae.
Because of the large variety of soil improvers and growing media, this method might not be appropriate in every detail for certain materials. This method might not be appropriate in every detail for certain products. In this case, different methods which are specific to these products can be used if necessary, for justified technical reasons.
Bodenverbesserungsmittel und Kultursubstrate - Probenvorbereitung - Teil 2: Probenvorbereitung für mikrobiologische Untersuchungen
Dieses Dokument legt die allgemeinen Anforderungen an die Vorbereitung von Proben und die Herstellung von Erstverdünnungen vor mikrobiologischen Untersuchungen von Bodenverbesserungsmitteln und Kultursubstraten fest. Dieses Verfahren ist insbesondere für die Probenvorbereitung vor mikrobiologischen Untersuchungen von z. B. E. coli, Salmonella spp. und Enterococcaceae bestimmt.
Aufgrund der großen Vielfalt an Bodenverbesserungsmitteln und Kultursubstraten eignet sich dieses Verfahren möglicherweise nicht in allen Einzelheiten für bestimmte Materialien. Dieses Verfahren ist für bestimmte Produkte nicht unbedingt bis ins Detail geeignet. In diesem Fall können andere Verfahren, die speziell auf diese Produkte zutreffen, angewendet werden, wenn dies aus gerechtfertigten technischen Gründen notwendig ist.
Amendements du sol et supports de culture - Préparation des échantillons - Partie 2 : Préparation des échantillons pour l’examen microbiologique
Le présent document spécifie les exigences générales pour la préparation des échantillons et des suspensions mères avant les examens microbiologiques des amendements du sol et supports de culture. Cette méthode est en particulier destinée à la préparation des échantillons avant les examens microbiologiques, par exemple, d’E. coli, de Salmonella spp. et d’Enterococcaceae.
En raison de la grande diversité des amendements du sol et supports de culture, cette méthode pourrait ne pas être appropriée dans le détail pour certains matériaux. Cette méthode pourrait ne pas être appropriée dans le détail pour certains produits. Dans ce cas, des méthodes différentes, spécifiques à ces produits, peuvent être utilisées si cela s’avère nécessaire pour des raisons techniques justifiées.
