4、6/EEC) and is intended to lead to CE marking. The date of applicability of EN 12566-3 as a harmonized European Standard, i.e. the date after which this standard may be used for CE marking purposes, is subject to an announcement in the Official Journal of the European Communities. The Commission in c

31、EN/TC 165 “Wastewater 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of an identical text or by endorsement, at the latest by January 2006, and conflicting national standards shall be withdrawn at
32、the latest by July 2008. This European Standard 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 inte
33、gral part of this European Standard. This European Standard provides the general requirements for packaged and/or site assembled treatment plants used for domestic wastewater treatment up to 50 PT (see Clause 1 “Scope“). The standard EN 12566 “Small wastewater treatment systems up to 50 PT“ contains
34、 the following Parts: Part 1: Prefabricated septic tanks; NOTE 1 This part specifies the requirements and test methods for prefabricated septic tank units. Part 2: Soil infiltration systems NOTE 2 This CEN/TS is a Code of Practice for in-situ constructed soil infiltration systems. No treatment requi
35、rements are specified. Part 3: Packaged and/or site assembled domestic wastewater treatment plants; NOTE 3 This part specifies the requirements and test methods used to evaluate packaged wastewater treatment plants which are required to treat sewage to a predetermined standard. The following Parts a

41、dard specifies requirements, test methods, the marking and evaluation of conformity for packaged and/or site assembled domestic wastewater treatment plants (including guest houses and businesses) used for populations up to 50 inhabitants. Small wastewater treatment plants according to this European
42、Standard are used for the treatment of raw domestic wastewater. It covers plants with tanks made of concrete, steel, PVC-U, Polyethylene (PE), Polypropylene (PP) and Glass Reinforced Polyester (GRP-UP). The test methods specified in this European Standard establish the performance of the plant, need
43、ed to verify its suitability for the end use (see 3.1). This European Standard applies for small wastewater treatment plants for use buried in the ground where no vehicle loads are applied to the product. This European Standard applies to plants where all prefabricated components are factory or site
44、-assembled by one manufacturer and which are tested as a whole. NOTE In some countries, domestic wastewater treatment plants are followed by other systems to conform to national regulations. 2 Normative references The following referenced documents are indispensable for the application of this Europ
