19、espect to potential adverse effects on the quality of water intended for human consumption caused by the product covered by this standard, the following is pointed out to the user: 1) This standard provides no information as to whether the product may be used without restriction in any of the Member

20、 States. 2) It should be noted that, while awaiting the adoption of verifiable European criteria, existing national regulation concerning the use and/or the characteristics of this product remain in force. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the

21、 following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia

22、, Spain, Sweden, Switzerland and United Kingdom. EN 14898:2006 (E) 5 1 Scope This European Standard specifies requirements relating to the construction, performance and methods of testing for active media filters for drinking water installations inside buildings, with a maximum working pressure of a

23、t least 1 000 kPa and a maximum working temperature of less than 30 C. It only concerns units, which are permanently connected to the mains supply at the point of entry or point of use. This standard applies only to filter systems comprising a housing and filter media tested together. It includes ca

24、psule type units where both the element and its outer housing are disposable. NOTE Products intended for use in water supply systems are to comply, when existing, with national regulations and testing arrangements that ensure fitness for contact with drinking water. The Member States relevant regula

25、tors and the EC Commission agreed on the principle of 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 adopted, European Standards on products will be amended by the addition of an Annex Z/EAS und

26、er 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 applicable. 2 Normative references The following referenced documents are indispensable for the app
