This European Standard shall be given the status of a national standard, either by publication of an ide
8、ntical text or by endorsement, at the latest by July 2008, and conflicting national standards shall be withdrawn at the latest by July 2008. This document supersedes EN 1407:1998. Significant technical differences between this edition and EN 1407:1998 are as follows: (a) reduction in the limit value
9、 for acrylamide from 250 mg/kg to 200 mg/kg in 4.4; (b) updating of the reference to the drinking water directive from 80/778/EEC to 98/83/EC; (c) provision of more information on treatment dose in Annex A. According to the CEN/CENELEC Internal Regulations, the national standards organizations of th
10、e 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, Netherlands, Norway, Poland, Portugal, Romania, Slovaki

EN 1407:2008 (E) 5 Introduction In respect of potential adverse effects on the quality of water intended for human consumption, caused by the product covered by this European Standard: 1) this European Standard provides no information as to
12、 whether the product may be used without restriction in any of the Member States of the EU or EFTA; 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. NO
13、TE Conformity with this European Standard does not confer or imply acceptance or approval of the product in any of the Member States of the EU or EFTA. The use of the product covered by this European Standard is subject to regulation or control by national authorities. EN 1407:2008 (E) 6 1 Scope Thi
14、s European Standard is applicable to anionic and non-ionic polyacrylamides used for treatment of water intended for human consumption. It describes the characteristics of anionic and non-ionic polyacrylamides and specifies the requirements and the corresponding test methods for anionic and non-ionic
15、 polyacrylamides. It gives information on their use in water treatment. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced
