The work of preparing International Standards is normally carried out through

31、 ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborate

32、s closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval cri

33、teria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject o

39、tems used for such rehabilitation.In recent years, the rehabilitation of pipeline systems has become increasingly important and will continue to be so.Pipeline systems are continuously required to satisfy physical, chemical, biochemical and biological demands. These demands depend on planning, mater

40、ial, construction, type and period of use.When pipeline systems become operational, proper system management has to be put in place. In addition to inspection and cleaning, rehabilitation of the pipeline can be required. Rehabilitation is carried out when there is a need to restore or upgrade the pe

41、rformance of a pipeline system. Rehabilitation can consist of repair, renovation or replacement.To coincide with the publication of ISO rehabilitation product standards for various application areas using methods other than renovation, the need to extend the scope of this document to include familie

42、s of trenchless replacement techniques was recognized.vi ISO 2017 All rights reservedBS EN ISO 11295:2017Classification and information on design and applications of plastics piping systems used for renovation and replacement1 ScopeThis document defines and describes families of techniques for the r

43、enovation and trenchless replacement (on or off the line of an existing pipeline) of non-pressure and pressure pipelines through the use of plastics pipes, including plastics composites formed in situ into pipes, fittings and ancillary components. It does not include new construction provided as net

44、work extension. For each technique family, it identifies areas of application including, but not limited to, underground drainage and sewerage, and underground water and gas supply networks.This document provides information on the principles of, but not the detailed methodologies for, the design of

45、 plastics piping systems used for renovation or trenchless replacement of existing pipelines, covering: existing pipeline and site conditions; functions of the new pipeline; structural performance; hydraulic performance; installation aspects and site impact; other factors affecting renovation or tre

46、nchless replacement technique selection.Necessary work on the existing pipeline prior to renovation and/or trenchless replacement is outside the scope of this document.This document provides information needed to determine viable options and for identification of the optimal technique with regard to

47、 a given set of rehabilitation objectives.NOTE It is the responsibility of the designer to choose and design the renovation or trenchless replacement system.It does not specify the calculation methods to determine, for each viable technique, the required amount of lining or replacement pipe material

48、 needed to secure the desired performance of the rehabilitated pipeline.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
