Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through 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 collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 11295 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the
transport of fluids.
This first edition of ISO 11295 cancels and replaces ISO/TR 11295:1992.

ISO 11295:2010(E)
Introduction
This International Standard classifies the techniques used for the renovation of existing pipelines and gives
information on the design of plastics piping systems used for such renovation.
Over the past 25 years, the rehabilitation of pipeline systems has become increasingly important.
Pipeline systems are continuously required to satisfy physical, chemical, biochemical and biological demands.
These demands depend on planning, material, 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 need for restoration or upgrading of the pipeline system in terms of its performance. Rehabilitation can
consist of repair, renovation or replacement.
To coincide with the publication of ISO product standards for various families of renovation techniques in three
different application areas, the need to upgrade ISO/TR 11295 to a full International Standard was recognized,
and, at the same time, focus on renovation.

INTERNATIONAL STANDARD ISO 11295:2010(E)

Classification and information on design of plastics piping
systems used for renovation
1 Scope
This International Standard 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.
This International Standard provides information on the principles of, but not the detailed methodologies for,
the design of plastics piping systems applied as linings to existing pipelines, covering:
⎯ existing pipeline and site conditions;
⎯ lining system functions;
⎯ structural performance;
⎯ hydraulic performance;
⎯ other factors affecting lining system selection.
It does not cover the calculation methods used to determine, for each viable technique, the required amount of
lining material needed to secure the desired performance of the renovated pipeline.
