This State Standard has been set by Technical Committee (TK 09) on ecology and has been registered by the Decision No. 006 of the Collegium of the State Committee for Standardisation, Metrology and Patent. This State Standard is authentic translation of ISO 8689-1:2000 Water quality -- Biological classification of rivers -- Part 1: Guidance on the interpretation of biological quality data from surveys of benthic macro-invertebrates. The initial inspection shall be in 2020 to determine the requirements of the standard to comply with the international standards, norms, rules and recommendations. This State Standard gives guidance on the interpretation of biological quality data relating to running waters from surveys of benthic macro-invertebrates. It is recognized that for a complete assessment of ecological status, other elements of biological quality should be assessed. Furthermore, 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 macro-invertebrates already exist.
