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

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
