EN 15885:2010 – Classification and characteristics of techniques for renovation and repair of drains and sewers
1 Scope
This European Standard specifies a system for 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 Standard 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 renovation 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 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.

lining pipe and all relevant fittings inserted into an existing pipeline for the purposes of renovation
[EN ISO 11295:2010, 3.3]
3.9
lining with continuous pipes
lining with pipe made continuous prior to insertion, and which has not been shaped to give it a cross-sectional diameter smaller than its final diameter after installation
[ISO 11296-1:2009, 3.2.1]
3.10
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

3.12
lining with discrete pipes
lining with short lengths of pipe which are jointed to form a continuous pipe one by one during insertion
3.13
lining with spirally-wound pipes
lining with a profiled strip, spirally wound to form a continuous pipe after installation
[ISO 11296-1:2009, 3.2.5]
