22、covered by this Standard: 1) this Standard provides no information as to 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 concernin
23、g the use and/or the characteristics of this product remain in force. NOTE Conformity with the 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 c
24、ontrol by National Authorities. DIN EN 15795:2010-12 EN 15795:2010 (E) 5 1 Scope This European Standard is applicable to natural unexpanded aluminosilicates used for treatment of water intended for human consumption. It describes the characteristics of natural unexpanded aluminosilicates and specifi
25、es the requirements and the corresponding test methods for natural unexpanded aluminosilicates and gives information on their use in water treatment. 2 Normative references The following referenced documents are indispensable for the application of this document.
