List of parameters

pH, conductivity, turbidity, REDOX potential, true colour by comparison with hexachloroplatinate

True colour analysed by spectrophotometry according to method C of the EN ISO 7887 standard. The determination of the true colour according to the method D of the EN ISO 7887 standard can be carried out; a statistical treatment of data obtained with this method may be considered if the number of results returned by the participants is sufficient
