Over deze norm
This European Standard is applicable to silver salts for the conservation of water intended for human consumption in intermittent applications in water supply plants, including their pipeline networks, with a maximum annual outflow of 1 000 m³ (small-size plants); water for the preparation of foodstuffs; and other water which is stored in packaged form or kept in enclosed systems (for example, water supply systems in land-, water- and airborne vehicles). Water which is to be conserved with silver shall fulfil the relevant legal requirements before the silver salt is added, in particular microbiological requirements. NOTE The purpose of adding silver salt is to prevent the detrimental proliferation of micro-organisms in water during storage or in enclosed supply systems.. This standard describes the characteristics of silver salts and specifies the requirements for silver salts and gives reference to the analytical methods. It gives information on its use in water treatment. It also determines the rules relating to safe handling and use of silver salts (see annex B) .
