This standard specifies a test method for determining the odour and flavour of test waters after their contact with the organic materials used in piping systems, where the term products comprises pipes, fittings and ancillaries including their coatings and joints. The test method described in this standard is applicable to products to be used under various conditions for the transport of water intended for human consumption and raw water used for the manufacture of water intended for human consumption. Coatings or protective layers on products which are not intended to be in contact with these types of water are not covered by this method. This standard specifies the test method comprising a set of procedures with and without a disinfection pretreatment and possible temperatures for the test waters. The use of the disinfection pretreatment and the choice of the test temperature are dependent on the relevant national regulations and/or the system or product standards.
