14、 potential adverse effects on the quality of water intended for human consumption, caused by the products covered by this European Standard: a) this European Standard provides no information as to whether the products may be used without restriction in any of the Member States of the EU or EFTA; b)
15、it should be noted that, while awaiting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of these products remain in force. NOTE 1 Conformity with this European Standard does not confer or imply acceptance or approval of the pr
16、oducts in any of the member states of the EU or EFTA. The use of the products covered by this European Standard is subject to regulation or control by national authorities. NOTE 2 Water which is to be preserved with silver should fulfil the relevant legal requirements before the silver salt is added
17、, in particular microbiological requirements.

19、ems (for example, water supply systems in land, water and airborne vehicles). The purpose of adding silver salts is to prevent the detrimental proliferation of microorganisms in water during storage or in enclosed supply systems. This European Standard describes the characteristics of silver salts a
20、nd specifies the requirements for silver salts and gives reference to the analytical methods. It gives information on their use in water treatment. It also determines the rules relating to safe handling and use of silver salts (see Annex B). 2 Normative references The following referenced documents
