22、cretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2017, and conflicting national standards shall be withdrawn at the latest by May 2018. Attention is draw
23、n to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12566-7:2013. This document has been prepared under a mandate given to CEN
24、by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. The differences between this version and EN 12566-7:2013 are mainly
25、 editorial changes according to the Construction Product Regulation (CPR) and declaration of power consumption and desludging during treatment efficiency test. The standard series EN 12566 “Small wastewater treatment systems for up to 50 PT” contains the following parts (see Figure 1): Part 1: Prefa
26、bricated septic tanks; Part 3: Packaged and/or site assembled domestic wastewater treatment plants; Part 4: Septic tanks assembled in situ from prefabricated kits; Part 6: Prefabricated treatment unit used for septic tank effluent; Part 7: Prefabricated tertiary treatment unit (this document). For f
27、iltration systems, CEN/TC 165 decided to publish the following CEN Technical reports, which are considered as Code of practices and do not specify treatment requirements: Part 2: Soil infiltration systems; Part 5: Pre-treated Effluent Filtration systems.

32、 European Standard specifies requirements, test methods, the marking and evaluation of conformity for a packaged and/or site assembled tertiary treatment unit (see Figure 1). It applies for tertiary treatment units that are placed on the market as complete units used for the tertiary treatment of do
33、mestic wastewater by biological, physical, chemical, electrical processes and coming from: a) units in accordance with EN 12566-3 or EN 12566-6; b) installations designed and constructed in accordance with CEN/TR 12566-5. Equivalent secondary treated effluent may come from existing systems. Package
34、and/or site assembled tertiary treatment units according to this standard consist of one or more watertight tanks without any direct infiltration into the ground, made of concrete, corrosion resistant or coated steel, un-plasticised poly-vinyl chloride (PVC-U), polyethylene (PE), glass reinforced th
35、ermosetting plastics (GRP) based on polyester resin (UP) (GRP-UP), polypropylene (PP), polydicyclopentadiene (PDCPD) and flexible sheets (HDPE, PP, PVE and EPDM). This standard applies to tertiary treatment units for use above ground (outside the building) or buried in the ground where no vehicle lo
36、ads are applied to the unit. This standard does not apply to tertiary treatment systems forming part of units covered by EN 12566-3 and EN 12566-6. This standard does not cover the systems for microorganism reduction. 2 Normative references The following documents, in whole or in part, are normative
