EN 14409-1:2004 (E) 3 Foreword
This document (EN 14409-1:2004) has been prepared by Technical Committee CEN/TC 155 "Plastics piping systems and ducting systems", the secretariat of which is held by NEN. 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of an identical text or by endorsement, at the latest by March 2005, and conflicting national standards shall be withdrawn at the latest by March 2005. This document is a part of a System Standard for plastics piping systems of various materials used for renovation of existing pipelines in a specified application area. System Standards for renovation dealing with the following applications are either available or in preparation: — Plastics piping systems for renovation of underground non-pressure drainage and sewerage networks; — Plastics piping systems for renovation of underground water supply networks (this application); — Plastics piping systems for renovation of underground gas supply networks; — Plastics piping systems for renovation of underground drainage and sewerage networks under pressure; — Plastics piping systems for renovation of industrial pipelines. These System Standards are distinguished from those for conventionally installed plastics piping systems by setting requirements for certain characteristics in the as-installed condition, after site processing.
This is in addition to specifying requirements for system components as manufactured.
Each of the System Standards comprises a: —
Part 1: General
and all applicable renovation technique family related parts from the following list:
—
Part 21): Lining with continuous pipes —
Part 3: Lining with close-fit pipes —
Part 41): Lining with cured-in-place pipes —
Part 61): Lining with inserted hoses A consistent structure of clause headings has been adopted for all parts to facilitate direct comparisons across renovation technique families. Figure 1 shows the common part and clause structure and the relationship between EN 14409 and the System Standards for other application areas. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard : Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

EN 14409-1:2004 (E) 5 Introduction The requirements for any given renovation technique family are covered by Part 1: General, applied in conjunction with the relevant other part.
For example, for the requirements relating to Lining with continuous pipes it is necessary to refer to both parts 1 and 2.
Complementary information is contained in ISO/TR 11295 [5] and a supporting standard, EN 13689 [1], listed in the bibliography. Not all technique families are applicable to every area of application, and this is reflected in the part numbers actually included in each System Standard.
For the present document, the parts 1, 21), 3, 4 1), and 6 1) of EN 14409 apply. Recommended schemes for assessment of conformity of the plastics piping system with all relevant requirements are provided by way of informative annexes to each part. Attention is also drawn to EN 805 which has been taken into account during the preparation of this document.
1) At the date of publication of this standard, the standardization work on prEN 14409-2 and prEN 14409-4 and prEN 14409-6 has not started. SIST EN 14409-1:2005



EN 14409-1:2004 (E) 6 1 Scope This document specifies the requirements and test methods for plastics piping systems used for renovation of underground water supply networks which transport water intended for human consumption, including raw water intake pipelines.
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. This part of EN 14409 deals with the general requirements common to all relevant renovation techniques as defined in 3.2. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Figure 2  Technique families for renovation of underground water supply networks using plastics pipes, within the scope of pipeline rehabilitation techniques The technique families within the scope of this document are defined as follows: 3.2.1 lining with continuous pipes lining with pipe made continuous for the length of the section to be renovated prior to insertion, and which has not been shaped to give it a cross-sectional diameter smaller than its final diameter after installation 3.2.2 lining with close-fit pipes lining with a continuous pipe for which the cross-section is reduced to facilitate installation and reverted after installation to provide a close fit to the existing pipe NOTE
For the reduction in cross-section there are two options as follows: a)
reduction in the pipe manufacturing plant; the pipe is usually supplied coiled on a reel from which it is directly inserted; b)
reduction on site; the pipe is usually fed through the reduction equipment and simultaneously inserted in one continuous string. SIST EN 14409-1:2005
