This European Standard specifies methods for identifying and calculating the relative proportions of diatom taxa on observation slides and for interpreting the results in water quality assessments of rivers and ponds. lakes. It can be used with indices and assessment methods based on the relative abundance of taxa. These identification and enumeration methods can also be applied to the study of benthic diatoms in other habitats provided that methods of interpreting the results are appropriate to the habitats considered.
