This European Standard shall be given the status of a national standard, eith
17、er 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of an identical text or by endorsement, at the latest by February 2017, and conflicting national standards shall be withdrawn at the latest by May 2018.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 drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or
18、CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12566-4:2007. 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 Di
19、rective(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 12566-4:2007 are mainly editorial changes according to the Construction Product Regulation (CPR). The standard series EN 12566 “Small w
20、astewater 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 (this document); Part 6: Prefabric

BS EN 12566-4:2016EN 12566-4:2016 (E) 6 1 Scope This European Standard specifies the requirements for septic tanks assembled in situ from prefabricated kits and ancillary equipment where applicable, used outside buildings for the partial treatment o
27、f domestic wastewater for a population up to 50 PT. Pipe sizes, loads, watertightness, marking and evaluation of conformity are specified. This European Standard does not apply to septic tanks receiving grey water only. 2 Normative references The following documents, in whole or in part, are normati
28、vely referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 681-1, Elastomeric seals Materials requirements for pipe join

30、s and definitions given in EN 12566-1:2016, EN 16323:2014 and the following apply. 3.1 kit complete set of components provided by a single manufacturer and assembled on its permanent site from a kit in order to form a septic tank 3.2 ancillary equipment pipe connections and internal components that
31、are part of the septic tank kit 3.3 product family group of products in which, for the purpose of evaluation, the selected property(s) is/are similar for all products within the group Note 1 to entry: The definition of family takes into account at least similar shape, equipment, materials and condit
32、ions of end use and ensures the minimum hydraulic efficiency and minimum structural behaviour for all the products in the range. Note 2 to entry: The minimum level of performance (hydraulic efficiency and structural behaviour) are given by the test carried out on one model of the family. BS EN 12566
33、-4:2016EN 12566-4:2016 (E) 7 4 Product characteristics Products according to this standard shall meet the requirements of EN 12566-1:2016, Clause 4. In addition to the specifications of EN 12566-1, elastomeric seals for joints shall conform to EN 681-1, where applicable. Where the product consists o
34、f more than one tank, the evaluation of the structural behaviour of the product family shall be carried out according to EN 12566-1 for each different sized tank. Where the product consists of more than one tank, the hydraulic efficiency test shall be done according to EN 12566-1 after assembling th
35、e tanks. Pipe connections and ancillary equipment shall be in accordance with the relevant standards. Durability is ensured by the product passing the relevant requirements for each essential characteristic, if they represent the state of the art. 5 Testing, assessment and sampling methods Products
36、according to this standard shall be tested according to EN 12566-1:2016, Clause 5 as relevant. 6 Assessment and verification of constancy of performance AVCP 6.1 General The compliance of the septic tank with the requirements of this standard and with the performances declared by the manufacturer in
37、 the DoP shall be demonstrated by: determination of the product type; factory production control by the manufacturer, including product assessment. The manufacturer shall always retain the overall control and shall have the necessary means to take responsibility for the conformity of the product wit
38、h its declared performance(s). 6.2 Type testing 6.2.1 General All performances related to characteristics included in this standard shall be determined when the manufacturer intends to declare the respective performances unless the standard gives provisions for declaring them without performing test
39、s. (e.g. use of previously existing data, CWFT and conventionally accepted performance). Assessment previously performed in accordance with the provisions of this standard, may be taken into account provided that they were made to the same or a more rigorous test method, under the same AVCP system o
40、n the same product or products of similar design, construction and functionality, such that the results are applicable to the product in question. NOTE 1 Same AVCP system means testing by an independent third party, and for reaction to fire under the responsibility of a notified product certificatio
41、n body (only for products covered by system 1+ and 1). For the purposes of assessment, the manufacturers products may be grouped into families, where it is considered that the results for one or more characteristics from any one product within the product family are representative for that same char
42、acteristics for all products within that same family BS EN 12566-4:2016EN 12566-4:2016 (E) 8 NOTE 2 Products may be grouped in different families for different characteristics. Reference to the assessment method standards should be made to allow the selection of a suitable representative sample. In
43、addition, the determination of the product type shall be performed for all characteristics included in the standard for which the manufacturer declares the performance: at the beginning of the production of a new or modified septic tank (unless a member of the same product family); or at the beginni
44、ng of a new or modified method of production (where this may affect the declared properties); or they shall be repeated for the appropriate characteristic(s), whenever a change occurs in the septic tank design, in the raw material or in the supplier of the components, or in the method of production
45、(subject to the definition of a product family), which would affect significantly one or more of the characteristics. Where components are used whose characteristics have already been determined, by the component manufacturer, on the basis of assessment methods of other product standards, these char
46、acteristics need not be re-assessed. The specifications of these components shall be documented. Products bearing regulatory marking in accordance with appropriate harmonized European specifications may be presumed to have the performances declared in the DoP, although this does not replace the resp
47、onsibility on the septic tank manufacturer to ensure that the septic tank as a whole is correctly manufactured and its component products have the declared performance values. 6.2.2 Test samples, testing and compliance criteria The number of samples of septic tank to be tested/assessed shall be in a
