23、-6:2016) has been prepared by Technical Committee CEN/TC 165 “Waste water engineering”, the secretariat 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
24、conflicting national standards shall be withdrawn at the latest by May 2018. Attention is drawn 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 docu
25、ment supersedes EN 12566-6:2013. This document has been prepared under a mandate given to CEN 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 integ
26、ral part of this document. The differences between this version and EN 12566-6:2013 are mainly 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
27、 treatment systems for up to 50 PT” contains the following parts (see Figure 1): Part 1: Prefabricated 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 units for
28、septic tank effluent (this document); Part 7: Prefabricated tertiary treatment unit. For filtration 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

31、he products described in the standard series EN 12566. Figure 1 Scheme related to the arrangement of the parts of EN 12566 or CEN/TR 12566 According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard:
32、 Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
33、Sweden, Switzerland, Turkey and the United Kingdom. BS EN 12566-6:2016EN 12566-6:2016 (E) 7 1 Scope This European Standard specifies requirements, test methods, evaluation of conformity and marking for prefabricated secondary treatment units used for the treatment of effluent from septic tanks accor
34、ding to EN 12566-1 or EN 12566-4 in small wastewater treatment systems for up to 50 PT. NOTE Equivalent septic effluent may come from existing septic tanks. It applies to the prefabricated secondary treatment unit, where all its components are packaged or site-assembled and placed on the market as a
35、 kit by one manufacturer. The prefabricated secondary treatment unit consists of one or more tanks made of concrete, steel, unplasticised polyvinylchloride (PVC-U), polyethylene (PE), glass reinforced polyester (GRP-UP), polypropylene (PP), polydicyclopentadiene (PDCPD) or container made of flexible
36、 sheets (HDPE, PP, PVC, EPDM). Other components specified by the manufacturer, such as pipes, pumps and filter material will be considered as part of the unit. This European Standard establishes the performance of the prefabricated secondary treatment units needed to verify their suitability for the
37、 end use conditions for which the test methods are specified. This European Standard applies for the packaged and/or site assembled secondary treatment units for use on the top of the ground (outside the building) or buried in the ground where no vehicle loads are applied to the unit. This European
38、Standard does not cover: non watertight secondary treatment units with direct infiltration into the ground; retrofit kits (see definition in 3.1.7). 2 Normative references The following referenced documents, in whole or in part, are normatively referenced in this document and are indispensable for i
