EN 13443-1:2002 (E)4IntroductionIn respect of potential adverse effects on the quality of water intended for human consumption, caused by theproduct covered by this standard:1) this standard provides no information as to whether the product may be used without restriction in any ofthe Member States of the EU or EFTA;2) it should be noted that, while awaiting the adoption of verifiable European criteria, existing nationalregulations concerning the use and/or the characteristics of this product remain in force.SIST EN 13443-1:2003



EN 13443-1:2002 (E)51 ScopePart 1 of this European Standard applies to mechanical filters for drinking water installations inside buildings, ofnominal size from DN 15 to DN 100, minimum nominal pressure PN10, particle rating of 80 µm to 150 µm, andminimum design temperature of 30 °C. It specifies requirements relating to the construction and mode of operationof filters and describes relevant methods of testing. It only concerns units which are permanently connected to themains supply at the point of entry into the building.Part 2 of this European Standard (prEN 13443-2) is a separate document and deals with filters with a particle sizelimit less than 80 µm.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision.

Examplesare given in annex A.4.2 Nominal size (DN)The nominal size DN shall correspond to the flow rates in Table 2. The inlet connection of the filter may be DN orone size larger or one size smaller than the nominal size DN. In the case of flange connections the nominal sizeDN is determined by the DN of the inlet connection.4.3 End ConnectionsExamples of end connections are shown in annex A. Combinations of two kinds of connections are possible.4.4 Filter TypeFilters conforming to this standard shall be presented as one of the following types:¾ filters requiring single use filter elements;SIST EN 13443-1:2003

The materials, inparticular copper alloys, shall conform to relevant national standards or recommendations. These references shallbe stated.Copper-zinc alloys containing more than 10 % zinc are subject to dezincification when submitted to water capableof dezincification. In countries where the use of products made of dezincification resistant material is required, theproduct have to guarantee a dezincification depth less than 200 µm in any direction. They have to be tested and marked inaccordance with EN ISO 6509 and have to be marked in compliance with the indications under clause 9 of the presentstandard.6 General design requirements6.1 Backwashable filtersBackwashable filters shall be able to be cleaned without the aid of tools. No substances shall be allowed topenetrate into the drinking water supply as a result of the cleaning operation. After completion of backwashing, theoriginal grade of filtration and pressure drop shall be recovered.Backwashable filters shall be provided with a backwash water outlet, conforming to EN 1717.It shall be possible to clean the filter mounted in any of the positions specified by the manufacturer with nointerruption of filtered water supply during backwashing.6.2 Single-use filtersSingle use filters shall be designed in such a way that the filter elements can be replaced without any risk ofcontamination of the drinking water. It shall be possible to replace the filter mounted in any of the positionsspecified by the manufacturer.Any tools used in this process shall not come into contact with drinking water and shall be provided by themanufacturer. If specific tools are necessary they shall be supplied by the manufacturer.Replacement filter elements shall be single packaged to prevent contamination from outside.6.3 Thermal stabilityFilters shall be designed to withstand room and water temperatures of at least 30°°C.SIST EN 13443-1:2003

Unless otherwisespecified tolerances shall be ± 5%. Unless otherwise stated tests shall be carried out at room temperature withwater between 10 °C and 30 °C. If the designed water temperature is higher than 30 °C, the designed temperatureshall be used for the test.8.2 Mechanical Performance8.2.1 Bending strength of the body8.2.1.1 PrincipleThe mechanical bending strength of the body is tested by a bending moment test, in which a force is applied for apredetermined period.SIST EN
