20、plies 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 of operation
21、 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 particle size limit

The designation shall be clearly identified on the manufacturers rating plate or in the instruction manual. E
32、xamples 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 determined b
33、y 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 single use filt

35、hall 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. The requirem
36、ents , 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 standards or
37、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 product have to g
