22、 the Member States of the EU or EFTA; b) it should be noted that, while awaiting 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
23、 imply acceptance or approval of the products in any of the Member States of 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 15031:2013-08 EN 15031:2013 (E) 5 1 Scope This European Standard is applicable to

25、duction of formulations for treatment of water for swimming pools. It describes the characteristics of aluminium based coagulants and specifies the requirements and the corresponding test methods for aluminium based coagulants. It gives information on their use in swimming pool water treatment. It a
26、lso determines the rules relating to safe handling and use (see Annex B). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
