This European Standard specifies methods for determining the TON and TFN of waters. It is essential that the safety remarks in clause 5 are taken into account. Two 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.
