This part of this European Standard applies to lifting plants for wastewater containing faecal matter for limited applications used for draining a single WC according to EN 33 or EN 37 to which it is directly connected and located below flood level. Plants for limited applications are those where the number of users is small, where there is another WC available above flood level, and the plants serve no more than one wash-hand basin, one shower and one bidet provided they pass the tests described in clause 8 and they are installed in accordance with EN 12056-1 and no other sanitary appliance is directly or indirectly connected. In addition, limited application means that the plant is located in the same room as the WC and any other appliance served by it. *) This part of this standard contains general requirements, basic construction and testing principles, together with information on materials and conformity evaluation. Construction and testing requirements for non-return valves used in faecal lifting plants for limited applications are given in EN 12050-4.
*)The installation of a faecal lifting plant for limited applications above flood level is normally not allowed but limited to exceptional cases described in EN 12056-1; lifting plants above flood level are not subject to this standard.
