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 11296-3 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the
transport of fluids.
ISO 11296 consists of the following parts, under the general title Plastics piping systems for renovation of
underground non-pressure drainage and sewerage networks:
⎯ Part 1: General
⎯ Part 3: Lining with close-fit pipes
⎯ Part 4: Lining with cured-in-place pipes
Lining with continuous pipes is to form the subject of a part 2, lining with discrete pipes is to form the subject
of a part 5 and lining with spirally-wound pipes is to form the subject of a part 7.

ISO 11296-3:2009(E)
Introduction
The System Standard, of which this is part 3, specifies the requirements for plastics piping systems of various
materials used for the renovation of existing pipelines in a specified application area. System Standards for
renovation specify procedures for the following applications:
⎯ plastics piping systems for renovation of underground non-pressure drainage and sewerage networks
(this application);
⎯ plastics piping systems for renovation of underground drainage and sewerage networks under pressure;
⎯ plastics piping systems for renovation of underground water supply networks;
⎯ plastics piping systems for renovation of underground gas supply networks.
These System Standards are distinguished from those for conventionally installed plastics piping systems
because they set requirements for certain characteristics in the as-installed condition, after site processing.
This is in addition to specifying requirements for plastics piping 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:
⎯ part 2: lining with continuous pipes;
⎯ 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.
The requirements for any given renovation technique family are given in part 1, applied in conjunction with the
other relevant part. For example, parts 1 and 2 specify the requirements relating to lining with continuous
pipes. For complementary information, see ISO 11295. Not all technique families are applicable to every area
of application and this is reflected in the part numbers included in each System Standard.
A consistent structure of clause headings has been adopted for all parts to facilitate direct comparisons across
renovation technique families.
Figure 1 gives the common structure and the relationship between ISO 11296 and the System Standards for
other application areas.

INTERNATIONAL STANDARD ISO 11296-3:2009(E)

Plastics piping systems for renovation of underground
non-pressure drainage and sewerage networks —
Part 3:
Lining with close-fit pipes
1 Scope
This part of ISO 11296, in conjunction with ISO 11296-1, specifies requirements and test methods for close-fit
lining systems intended to be used for the renovation of non-pressure drainage and sewerage networks.
It applies to pipes and fittings made of polyethylene (PE) or unplasticized poly(vinyl chloride) (PVC-U). It is
applicable to the plastic lining system only. It is not applicable to the requirements for the existing pipeline.

For the purposes of this document, the terms and definitions given in ISO 11296-1 and the following apply.
3.1

location of the outside of the installed liner relative to the inside of the existing pipeline, which may either be
an interference fit or include a small annular gap resulting from shrinkage and tolerances only
3.2

continuous lining pipe of thermoplastic material reshaped or otherwise expanded after insertion to achieve a
close fit to the existing pipeline

5.1.2 Distinction between PVC-U types
PVC-U materials used for liner pipes may have PVC content less than the minimum of 80 %, and/or Vicat
softening temperature less than the 79 °C specified by ISO 4435. For the purposes of this part of ISO 11296,
distinction shall be made between PVC-U conforming to ISO 4435 (designated standard PVC-U) and PVC-U
modified for lining applications.
NOTE This distinction is reflected in the requirements given in Table 4 and Table 11.
5.1.3 Virgin material
Virgin material, as defined in ISO 11296-1, may be used without limitations. Fusion compatibility of PE pipes
shall conform to ISO 8772:2006, 4.6.
5.1.4 Reprocessable material and recyclable material
5.1.4.1 Reprocessable material
Own reprocessable material may be used, provided that it is derived from the same compound used for the
relevant production. External reprocessable material shall not be used.
5.1.4.2 Recyclable material
Recyclable material shall not be used.
5.2 General characteristics
When viewed without magnification the internal and external surfaces of the pipe shall be smooth, clean and
free from scoring, cavities and other defects, which would prevent conformity to this part of ISO 11296.
5.3 Material characteristics
When tested in accordance with the methods given in Table 1 or Table 2, as applicable, the material from
which the pipes are made shall conform to the requirements given in the relevant table.
