Foreword
This document (EN 13566-2:2005) 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text or by endorsement, at the latest by May 2006, and conflicting national standards shall be withdrawn at the
latest by November 2007.
This standard 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
(this application);
Plastics piping systems for renovation of underground water supply networks;
Plastics piping systems for renovation of underground gas supply networks;
Plastics piping systems for renovation of underground pressure drainage and sewerage networks;
Plastics piping systems for renovation of industrial pipe systems.
These system standards are distinguished from system standards for conventionally installed plastics piping
systems by the requirement to verify certain characteristics in the “as installed” condition, after site processing.
This is in addition to verification of characteristics of plastics piping systems “as manufactured”.
System standard EN 13566 comprises six parts, as follows:
Part 1: General
Part 2: Lining with continuous pipes (this standard)
Part 3: Lining with close-fit pipes
Part 4: Lining with cured-in-place pipes
Part 5: Lining with discrete pipes
Part 7: Lining with spirally wound pipes
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 13566 and system
standards for other applications.
Annex A of this document is informative. Annexes B, C and D are normative.
This document includes a bibliography.
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.

same as at the “M” stage.
NOTE 2 Out-of-roundness of the lining system after installation (including grouting of the annular space where
applicable) should not exceed any maximum value specified by design or otherwise agreed between the customer and
installer.

8 Installation practice
8.1 Preparatory work
The preparatory work shall conform to EN 13566-1:2002.
NOTE Depending on the condition of the existing pipeline, it is possible that cleaning is necessary. Cleaning prior to
insertion is important if the annular space is to be grouted.
8.2 Storage, handling and transport
Precautions shall be taken to ensure that no damage is caused to the lining pipe during unloading, site
handling and storage. In this context, damage shall mean any scratch which is more than 10 % of the wall
thickness in depth, or the imposition of any severe bending operation which results in a permanent kink,
crease or fold.
NOTE The lining pipe should be stored on reasonably level ground, free of large sharp stones, debris or litter, to
avoid potentially damaging point-loading.
