This document, in conjunction with ISO 11296-1, specifies requirements and test methods for pipes which are formed on site by spirally winding and jointing a pre-manufactured profiled plastics strip, or a profiled plastics strip and integral locking joiner strip, and used for the renovation of underground non-pressure drainage and sewerage networks.
It applies to spirally-wound pipes of fixed or variable diameter made of profiled plastics strips, with or without steel stiffening elements, and installed by one of two methods.
The first method employs a dedicated winding machine in front of the open end of an existing pipeline, e.g. in a manhole. The pipes thus formed are simultaneously inserted into the existing pipeline by the winding forces, and by certain techniques can also be expanded in diameter after or during insertion.
The second method employs a dedicated winding machine which forms the pipe as it traverses the existing pipeline from one manhole to the next.
It applies to profiled plastics strips of unplasticized poly(vinyl chloride) (PVC U) with integral locking mechanism, or of high density polyethylene (HDPE) with integrally welded joints.

ISO 11295:2017 defines and describes families of techniques for the renovation 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 network 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.
ISO 11295:2017 provides information on the principles of, but not the detailed methodologies for, the design of 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 trenchless replacement technique selection.
Necessary work on the existing pipeline prior to renovation and/or trenchless replacement is outside the scope of ISO 11295:2017.
ISO 11295:2017 provides information needed to determine viable options and for identification of the optimal technique with regard to 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 needed to secure the desired performance of the rehabilitated pipeline.

ISO 11295:2010 defines and describes families of techniques for the renovation of non‑pressure and pressure pipelines through the use of plastics pipes, fittings and ancillary components. For each technique family, it identifies areas of application from the range covered by existing renovation product standards, which include underground drainage and sewerage, and underground water and gas supply networks.
ISO 11295:2010 provides information on the principles of, but not the detailed methodologies for, the design of plastics piping systems applied as linings to existing pipelines.

This part of EN 13566, read in conjunction with EN 13566-1, specifies requirements and test methods for pipes that are formed on site by spirally winding and jointing a pre-manufactured profiled plastics strip using a winding machine in front of the open end of an existing pipeline (e.g. in a manhole). The pipes thus formed are simultaneously inserted into the existing pipeline by the winding forces.
It covers spirally-wound pipes of a fixed diameter made of profiled plastics strips of unplasticized poly(vinyl chloride) (PVC U) with an integral locking mechanism. These spirally-wound pipes are used for renovating non-pressure drainage and sewerage networks and are fixed in place by grouting the annular space.
NOTE   The grouting procedure is outside the scope of this standard.

This document specifies the requirements and test methods for plastics piping systems used for renovation of underground gas supply networks. It is applicable to pipes and fittings as manufactured as well as to the installed lining system; it does not cover sprayed coatings, the existing pipeline or any annular filler.
Functional recommendations on this subject are covered by EN 12007 parts 1 and 4.
This part of EN 14408 deals with the general requirements common to all relevant renovation techniques as defined in 3.2.

This part 3 of EN 14408, in conjunction with EN 14408-1:2004 specifies requirements and test methods for close-fit lining systems intended to be used for the renovation of gas supply networks.
It covers polyethylene (PE) pipe for both independent and interactive pressure pipe liners and associated fittings and joints for the construction of the lining system. It is applicable to the plastic lining system intended to be used under the following conditions:
a)   a maximum operating pressure, MOP, up to and including 10 bar 1);
b)   an operating temperature of 20 °C as reference temperature.
NOTE   For other operating temperatures, de-rating coefficients may be used, see EN 1555 5.

This Part 3 of prEN (155wi209), read in conjunction with Part 1, specifies requirements and test methods for pipes and fittings which are part of plastics piping systems installed as close-fit pipes in the renovation of non-pressure drainage and sewerage networks. It covers components made of polyethylene (PE) or unplasticized polyvinyl chloride (PVC-U). It is applicable to the plastic lining system only. It does not cover the requirements for the existing pipeline.
