27、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) it should be noted that, while awa

28、iting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of these products remain in force. NOTE Conformity with this European Standard does not confer or imply acceptance or approval of the products in any of the Member States o

29、f the EU or EFTA. The use of the products covered by this European Standard is subject to regulation or control by National Authorities. DIN EN 15039:2014-07 EN 15039:2014 (E) 5 1 Scope This European Standard is applicable to polycarboxylic acids and salts used as antiscalants for membranes for the

30、treatment of water intended for human consumption. It describes the characteristics and specifies the requirements and the corresponding analytical methods for polycarboxylic acids and salts. It gives information on their use as antiscalants for membranes in water treatment. 2 Normative references T
