EN 16070:2014 (E) 5 1 Scope This European Standard is applicable to natural zeolites used for treatment of water intended for human consumption. It describes the characteristics of natural zeolites and specifies the requirements and the corresponding test methods for natural zeolites. It gives information on their use in water treatment. The natural zeolites included in this standard are clinoptilolite, chabasite and phillipsite/analcime. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

However, not all natural zeolites can be used in the treatment of water intended for human consumption. Given the particular characteristics needed for this type of application, only three species are identified: clinoptilolite, chabazite and phillipsite/analcime. These zeolites are available in large quantities in Europe, with no trace of hazardous or toxic elements. 5 Physical properties 5.1 Appearance The product consists of dry, free flowing granules. The product has a granular shape and a rough texture. The product shall be generally homogeneous and shall be visibly free of extraneous matter. 5.2 Particle size distribution The particle size distribution shall be determined on samples taken at the point of manufacture using the method of test given in EN 12902. NOTE 1 The particle size can decrease during transportation and handling. The particle size distribution shall be described by either: a) effective size: (d10) with a maximum deviation of ± 5 %; median size: (d50) with a maximum deviation of ± 5 %;

1) Chemical Abstracts Service Registry Number. 2) European Inventory of Existing Commercial Chemical Substances. SIST EN 16070:2014

EN 16070:2014 (E) 7 uniformity coefficient: (U) shall be less than 1,5; minimum size: (d1) with a maximum deviation of ± 5 %; or b) by particle size range and by mass fraction of oversize and undersize particles (see A.2.2.1). The maximum permitted mass fractions of oversize and undersize are 5 %. NOTE 2 Other values might be necessary for certain applications. 5.3 Density (bulk density loose) The bulk density loose shall be in the range of: — 800 kg/m3 to 1 100 kg/m3 for a clinoptilolite type zeolite; — 700 kg/m3 to 850 kg/m3 for a chabazite type zeolite; — 1 000 kg/m3 to 1 100 kg/m3 for a phillipsite/analcime type zeolite. 6 Chemical and mineralogical properties 6.1 General This European Standard specifies the minimum purity requirements for natural zeolite used for the treatment of water intended for human consumption. Limits are given for impurities commonly present in the product. Depending on the raw material and the manufacturing process, other impurities may be present and, if so, this shall be notified to the user and when necessary to relevant authorities. Users of this product should check the national regulations in order to clarify whether it is of appropriate purity for treatment of water intended for human consumption, taking into account raw water quality, contents of other impurities and additives used in the product not stated in this product standard. Limits have been given for impurities and chemical parameters where these are likely to be present in significant quantities from the current production process and raw materials. If the production process or raw materials lead to significant quantities of impurities, by-products or additives being present, this shall be notified to the user. The composition of the commercial product shall conform to Table 1. Table 1 — Composition of commercial product Parameters Limit in mass fraction % Mass loss at 150 °C max.

7 Ignition loss at 650 °C max.

14 After filling, washing and commissioning of a filter system producing drinking water, natural zeolite should not increase the concentrations of chemical parameters (see[1]). NOTE Water extractable substances, determined in accordance with the method for granular materials given in EN 12902, can be used to estimate the leaching of the chemicals s
