Popis
BS EN ISO 8689-1:2000
This standard BS EN ISO 8689-1:2000 Water quality. Biological classification of rivers is classified in these ICS categories:
- 13.060.10 Water of natural resources
- 13.060.70 Examination of biological properties of water
This part of ISO 8689 gives guidance on the interpretation of biological quality data relating to running waters from surveys of benthic macroinvertebrates. It is recognized that for a complete assessment of ecological status, other elements of biological quality should be assessed.
NOTE Annex A gives guidance on how the comparison of the various classification systems can be made where classifications of the biological quality of running waters using benthic macroinvertebrates already exist.
