EN 12050-2:2015 (E) 5 1 Scope This European Standard applies to lifting 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 requirements, 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 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 purchased 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.

EN 12050-2:2015 (E) 11 4.7.3 Plants classified according to test results 4.7.3.1 Principle For the purpose of the reaction to fire performance of the plant each of its constituent materials, including those in surface coating of the plant, if any, shall be classified according to EN 13501-1 and only the lowest class of such materials shall be declared. The class of an individual constituent material shall be obtained as the result of the test method(s), relevant to this class, and as specified in the standards referred to in EN 13501-1. NOTE A constituent material of the plant is considered as one which may have a significant effect on the reaction to fire performance of such a plant. According to the definitions given in EN 13501–1, this may be in the case of: — a homogeneous plant, its material, or — a non-homogeneous plant, its substantial component (i.e. a material that constitutes a significant part of such plant). A layer with a mass per unit area ≥ 1,0 kg/m2 or a thickness ≥ 1,0 mm is considered to be a substantial component. Test specimens used for the test methods applicable for this classification shall be prepared according to EN 13501-1 and to the relevant standards referred therein. In addition, with regard to the SBI test according to EN 13823, when applied, the test specimen shall be prepared and mounted as specified in 4.7.3.2. 4.7.3.2 Sizes and mounting of the test specimen The test specimen of each constituent material shall be in accordance with EN 13823 in a flat-sheet form of the following sizes: — short wing: (495 ± 5) mm × (1 500 ± 5) mm; — long wing: (1 000 ± 5) mm × (1 500 ± 5) mm. 4.8 Noise level The manufacturer shall declare the A-weighted emission sound pressure level (to be measured at 1 m distance from the plant). Measurements shall be performed according to EN ISO 20361. The pump shall operate in best efficiency point during this measurement. If an A-weighted emission sound pressure level is above 80 dB, the sound power level shall be determined according to EN ISO 20361 and shall be declared. Where the manufacturer declares that the A-weighted emission sound pressure level is equal to 70 dB, although it might be smaller, the manufacturer may state “70 dB(A)”. If the manufacturer declares a lower value of the sound pressure level than 70 dB(A) the plant shall be measured according to EN ISO 20361 and the corresponding test result shall be declared. 4.9 Durability 4.9.1 General Lifting plants for faecal-free wastewater are products of known and stable performance for defined end use applications with respect to their established durability for which experience has been accumulated over a long period of time. Durability is ensured by meeting the requirements of this standard, which represent the state of the art. SIST EN 12050-2:2015



EN 12050-2:2015 (E) 12 For new materials the manufacturer has to take appropriate measures to verify that the lifting plant made of the new material is in accordance with the performance characteristics required by this standard. 4.9.2
