15、 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 June 2011, and conflicting
16、national standards shall be withdrawn at the latest by June 2011. 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. It provides an overv
17、iew of systems used for renovation and repair of drains and sewers, regardless of the material used. In respect of sewer renovation techniques using plastics materials only, it reproduces definitions and other information (but no requirements) contained in EN ISO 11295. Due to their continuous devel
18、opment the most up-to-date information on these particular techniques may be contained in either this document or EN ISO 11295, whichever is the latest dated edition. Regarding general requirements for drain and sewer systems and existing standards and draft standards on the subject of rehabilitatio
19、n of drain and sewer systems, information in summary form is available in CEN/TR 15128. For management and control of rehabilitation activities in drains and sewers a European Standard is in preparation in CEN/TC 165/WG 22. This document refers to existing EN product standards to the extent availabl
20、e for the techniques and materials covered. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France
21、, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. BS EN 15885:2010EN 15885:2010 (E) 4 1 Scope This European Standard specifies a system for
22、the classification of techniques for renovation and repair of drains and sewers outside buildings, operated under gravity or pressure, including pipes, connections and manholes. It defines and describes families of techniques and their different generic methods and materials used. This European Stan
23、dard does not describe specific products. For each technique family it lists relevant existing standards, materials and applications and outlines characteristics including installation aspects, structural and hydraulic capabilities and site impact. Necessary work on the existing pipe prior to renova
24、tion and repair is outside the scope of this European Standard. This European Standard provides information needed to determine viable options for identification of the optimal technique with regard to a given set of renovation and repair objectives. NOTE It is the responsibility of the designer to
25、choose and design the renovation and repair systems. It does not specify the calculation methods to determine, for each viable technique, the required amount of lining material needed to secure the desired performance of the renovated pipeline. 2 Normative references The following referenced documen

45、 5.1 General Renovation technique families within the scope of this European Standard are shown in Figure 1. This clause establishes a classification of renovation techniques into families, where renovation is applied to continuous lengths of drain or sewer usually between two or more access points.
46、 Individual techniques shall be classified into families according to 5.2 to 5.9 where the different renovation technique families are defined and their respective features, including materials, applications, as well as geometric, performance and installation characteristics, are described. aOutside
47、 the scope of this European Standard. bOther renovation techniques, which do not fit into the above families, are outside the scope of this European Standard which covers only technique families commonly available at the time of drafting.
