BS EN 12050-2:2015EN 12050-2:2015 (E) 5 1 Scope This European Standard applies to liftin
29、g plants for faecal-free wastewater for drainage of locations below flood level in buildings and sites to prevent any backflow of wastewater into the building. These lifting plants may be prefabricated or delivered as prefabricated kits and assembled on site. This standard specifies general requirem
30、ents, basic construction and testing principles, together with information on materials and assessment and verification of constancy of performance. Construction and testing requirements for non-return valves used in wastewater lifting plants are given in EN 12050-4. This European Standard does not
31、apply for pumping installations for drain and sewer systems outside buildings for pumping of municipal wastewater according to EN 752:2008, Annex F. This European Standard applies also to lifting plants for faecal-free wastewater which are not prefabricated but composed of individual components purc
32、hased from different suppliers and put together on site. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
