20、y 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 concerning the use and/or the characteristics of this product remain in force. EN 13443-1:2002+A1:2007 (E) 5 1 Scope Part 1 of this Europea
21、n Standard applies to mechanical filters for drinking water installations inside buildings, of nominal size from DN 15 to DN 100, minimum nominal pressure PN10, particle rating of 80 m to 150 m, and !maximum“ design temperature of 30 C. It specifies requirements relating to the construction and mode
22、 of operation of filters and describes relevant methods of testing. It only concerns units which are permanently connected to the mains supply at the point of entry into the building. Part 2 of this European Standard (!EN 13443-2:2005+A1“) is a separate document and deals with filters with a particl

32、es not exceed the maximum specified value, whichever is lower 4 Classification 4.1 Principle Mechanical filters shall be designated by: nominal size DN; end connections; filter type; nominal pressure PN. The designation shall be clearly identified on the manufacturers rating plate or in the instruct
33、ion manual. Examples are 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 or one size larger or one size smaller than the nominal size DN. In the case of flange connections the nominal size DN is
34、 determined by the DN of the inlet connection. 4.3 !End connections“ Examples of end connections are shown in !Annex A“. Combinations of two kinds of connections are possible. 4.4 !Filter type“ Filters conforming to this standard shall be presented as one of the following types: filters requiring si
35、ngle use filter elements; EN 13443-1:2002+A1:2007 (E) 7 backwashing filters filter elements cleaned by backwashing ( without any dismantling). 4.5 !Nominal pressure (PN)“ The nominal pressure PN shall correspond to EN 1333. 5 !Materials (chemical and hygienic behaviour of materials)“ The selection o
36、f materials shall be the responsibility of the manufacturer, provided that the complete filter satisfies the requirements of EN 1567. NOTE The materials and coatings used should not contaminate or change the drinking water, when in normal or accidental contact up to the maximum designed temperature.
37、 The requirements , with regard to the effects of materials on drinking water quality, are specified in national regulations. The manufacturer shall state in his technical literature what materials and coatings are used. The materials, in particular copper alloys, shall conform to relevant national
38、standards or recommendations. These references shall be stated. Copper-zinc alloys containing more than 10 % zinc are subject to dezincification when submitted to water capable of dezincification. In countries where the use of products made of dezincification resistant material is required, the prod
39、uct have to guarantee a dezincification depth less than 200 m in any direction.
