A sample represents the quality of the entire volume of the product under consideration

produced by reaction with alkalis

irrespective of their method of manufacture

The training of mechanics as discussed in BS 6574 focuses on such aspects in addition to the actual maintenance

Determination of the threshold odour number (TON) and threshold flavour number (TFN) Ingestion-build-258901 A sample represents the qualityWhat is BS EN 1622 Determination of the threshold odour number (TON) and threshold flavour number (TFN) about? 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: A short method applicable when either a sample has no odour and
