BS EN 1622 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:
Both methods described in BS EN 1622 are applicable for quantifying the odour and flavour of drinking water and/or migration waters from materials in contact with waters.
NOTE: The choice of the quantitative or qualitative method is depending on the national regulations, and on the type of water to be assessed (raw water, distribution water, migration water ….)
BS EN 1622 on the determination of the threshold odour number (TON) and threshold flavour number (TFN) is useful for:
Threshold Odor Numbers are whole numbers that indicate how many dilutions it takes to produce odor-free water
BS EN 1622 provides you with apparatus, sampling, transport, storage, and preparation of test pieces, preparation of reagents and apparatus, pre-treatment of test pieces, test procedure, and much more.
BS EN 1622 gives quantitative methods for the determination of the threshold odour number (TON) and the threshold flavour number (TFN).
The test methods and procedures provided by BS EN 1622 assist you in the determination of the threshold odour number and threshold flavour number of water in piping systems and ensure reducing the risk of severe health issues.
With obedience and compliance to BS EN 1622, you can enhance the efficacy of the water and manufacture a standardized product.
