19、existing national regulations concerning the use and/or the characteristics of these products remain in force. NOTE Conformity with the document does not confer or imply acceptance or approval of the products in any of the Member States of the EU or EFTA. The use of these products covered by this do
20、cument is subject to regulation or control by National Authorities. DIN EN 15797:2010-04 EN 15797:2010 (E) 5 1 Scope This European Standard is applicable to iron based coagulants (iron (III) chloride, iron (III) chloride sulfate and iron (III) sulfate liquid) used directly or for the production of f
21、ormulations for treatment of water for swimming pools. It describes the characteristics of iron based coagulants and specifies the requirements and the corresponding test methods for iron based coagulants. It gives information on their use in swimming pool water treatment. General information on iro
22、n based coagulants is given in Annex A. It also determines the rules relating to safe handling and use (see Annex B). 2 Normative references The following referenced documents are indispensable for the application of this document.
