This European Standard specifies quantitative methods for determining the TON and TFN of waters and also a qualitative method for determining any abnormal odour and/or flavour. It is essential that the safety remarks in Clause 5 are taken into account. Two quantitative methods are described: - a short method applicable when either a sample has no odour and flavour or when the odour and flavour are to be compared with a specified threshold number; - a full method applicable when the threshold number for the sample is to be determined. For both quantitative methods, two different methodologies are described: - unforced choice in the standard, - forced choice in Annex B. Both methods are applicable for quantifying the odour and flavour of drinking water and/or migration waters from materials in contact with waters.
