17、s on the quality of water intended for human consumption caused by the product covered by this standard:a)this standard provides no information as to whether the product may be used without restriction in any of theMember States of the EU or EFTA;b)it should be noted that, while awaiting the adoptio
18、n of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of this product remain in force.NOTEConformity with this 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 th
19、e product covered by this European Standard is subject to regulation or control by National Authorities.1ScopeThis European Standard is applicable to granular activated alumina used for treatment of water intended for human consumption. It describes the characteristics of granular activated alumina
20、and specifies the requirements and the corresponding test methods for granular activated alumina. It gives information on its use in water treatment.2Normative referencesThe following referenced documents are indispensable for the application of this document.
