This document shall be given the status of a national standard, either by publication of an identical text or by e
16、ndorsement, at the latest by May 2008 and conflicting national standards shall be withdrawn at the latest by May 2008. This document includes Amendment 1, approved by CEN on 2007-10-21. This document supersedes EN 15219:2006. The start and finish of text introduced or altered by amendment is indicat

With respect of potential adverse effects on the quality of water intended for human consumption caused by the product covered by this European Standard, the following is pointed out to the user: 1) this European Standard provides no information as to whether the product
18、may be used without restriction in any of the Member States; 2) it should be noted that, while awaiting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of this product remain in force. According to the CEN/CENELEC Internal Reg
19、ulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Net

DIN EN 15219:2008-02 EN 15219:2006+A1:2007 (E) 4 1 Scope This European Standard specifies requirements relating to the construction and mode of operation and relevant methods for testing a
21、utomatic, salt-regenerated, anion exchange nitrate removal devices for drinking water installations inside buildings, which are permanently connected to the mains supply. NOTE Products intended for use in water supply systems are to comply, when existing, with national regulations and testing arrang
22、ements that ensure fitness for contact with drinking water. The Member States relevant regulators and the EC Commission agreed on the principle for a future unique European Acceptance Scheme (EAS) which would provide a common testing and approval arrangement at European level. If and when the EAS is
23、 adopted, European Standards on products will be amended by the addition of an Annex Z/EAS under Mandate M/136, which will contain formal references to the testing, certification and product marking requirements of the EAS. Until the EAS comes into force, the current national regulations remain appl
24、icable. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
