Article 6
1
For the purposes of implementing Article 5, the designated waters shall be deemed to conform to this Directive if samples of such waters, taken at the minimum frequency specified in Annex I at the same sampling point and over a period of 12 months, show that they conform to both the values set by the Member States in accordance with Article 3 and the comments contained in columns G and I of Annex I, in the case of:
a
95 % of the samples for the parameters: pH, BOD5, nitrites, non-ionised ammonia, total ammonium, total residual chlorine, total zinc and dissolved copper. When the sampling frequency is lower than one sample per month, both the abovementioned values and comments shall be respected for all the samples;
b
the percentages listed in Annex I for the parameters: temperature and dissolved oxygen;
c
the average concentration set for the parameter: suspended solids.

Instances in which the values set by Member States in accordance with Article 3 or the comments contained in columns G and I of Annex I are not respected shall not be taken into consideration in the calculation of the percentages provided for in paragraph 1 when they are the result of floods or other natural disasters.
