Water quality - Guidance standard for the routine sampling and pretreatment of benthic diatoms from rivers
This guidance standard establishes a method for sampling and laboratory preparation of benthic diatoms for water quality assessments and studies of temporal change in running waters. It is suitable for use with indices based on the relative abundance of taxa. With appropriate modifications the method can be applied to the study of benthic diatoms in lakes.

Qualité de l'eau - Guide pour l'échantillonnage en routine et le prétraitement des diatomées benthiques de rivières
La présente Norme européenne est un guide qui établit une méthode pour l'échantillonnage et la préparation en laboratoire de diatomées benthiques en vue d'évaluer la qualité de l'eau. Les données obtenues par cette méthode conviennent pour la production d'indices de la qualité de l'eau basés sur l'abondance relative des taxons. Avec des modifications appropriées, cette méthode peut s'appliquer à l'étude des diatomées benthiques dans les lacs.
