Annotation of standard text ČSN EN 13946 (757707):

This document specifies a method for the sampling and laboratory preparation of benthic diatoms for ecological status and water quality assessments. The sampling and preparation procedures described can be used for later investigations using either light microscopy or molecular methods. Data produced by this method are suitable for production of indices based on the relative abundance of taxa.
Analysis using molecular methods is not within the scope of the document
