30、2050-3:2015EN 12050-3:2015 (E) 5 1 Scope This European Standard applies to lifting plants for limited applications for domestic non-commercial wastewater containing or not containing faecal matter and located below flood level. NOTE Limited application means that the number of users is small and the
31、 plant is located in the same room as the sanitary appliance(s) served by it1)which are installed in accordance with EN 120561 and the layout and calculation are in accordance with EN 120564. This European Standard applies to lifting plants for limited applications designed for wastewater containing
32、 faecal matter, where there is another WC available above flood level, and the plants serve no more than a single WC to which it is directly connected (at a distance of max. 0,5 m) and one hand washbasin, one shower and one bidet provided no other sanitary appliance is directly or indirectly connect
33、ed. This European Standard also applies to lifting plants for limited applications designed for faecal free wastewater, where a maximum of one hand washbasin or kitchen sink plus one further appliance such as a bathtub or a washing machine or a shower or a dish washer or an urinal are connected. No
34、other sanitary appliance shall be directly or indirectly connected. This European Standard contains general requirements, basic construction and testing principles, together with information on materials. Construction and testing requirements for non-return valves used in wastewater lifting plants f
35、or limited applications are given in EN 12050-4. This European Standard does not apply for lifting plants for limited applications for wastewater containing faecal matter where WC flushing is carried out by pressure flush valve. 2 Normative references The following documents, in whole or in part, ar
