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 11297-3 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the
transport of fluids.
ISO 11297 consists of the following parts, under the general title Plastics piping systems for renovation of
underground drainage and sewerage networks under pressure:
— Part 1: General
— Part 3: Lining with close-fit pipes
Lining with continuous pipes is to form the subject of a future part 2; lining with cured-in-place pipes is
to form the subject of a future part 4; lining with discrete pipes is to form the subject of a future part 5;
and lining with adhesive-backed hoses is to form the subject of a future part 6.
This corrected version of ISO 11297-3:2013 incorporates the following corrections:
— Clause 2: correction of the title of EN 12201-4.
— Table 2: addition of an explanation for table footnote “a”.

Introduction
System standards 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 drainage and sewerage networks under
pressure (this application);
— 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 by the requirement to verify certain characteristics in the as-installed condition, after site
processing. This is in addition to specifying requirements for plastics piping system components as
manufactured.
This System Standard ISO 11297 comprises a:
— Part 1: General
and the following technique family-related parts:
— 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 6: Lining with adhesive-backed hoses
The requirements for any given renovation technique family are given in part 1 applied in conjunction
with the relevant other part. For example, both ISO 11297-1 and this part of ISO 11297 together specify
the requirements relating to lining with close-fit pipes. For complementary information, see ISO 11295.
Not all technique families are pertinent 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 of ISO 11297, in order to facilitate
direct comparisons across renovation technique families.
Figure 1 shows the common part and clause structure and the relationship between ISO 11297 and the
system standards for other application areas.

Part 3:
Lining with close-fit pipes
1 Scope
This part of ISO 11297, in conjunction with ISO 11297-1, specifies requirements and test methods for
close-fit lining systems intended to be used for the renovation of underground drainage and sewerage
networks under pressure. It is applicable to pipes and fittings, as manufactured, as well as to the installed
lining system. It is applicable to polyethylene (PE) pipe for both independent and interactive pressure
pipe liners as well as associated fittings and joints for the construction of the lining system.

joint made by assembling a PE pipe to another PE pipe or any other element of the piping system, using
a fitting that generally includes a compression part to provide for pressure integrity and leaktightness
and a gripping part to provide resistance to end loads
Note 1 to entry: A support sleeve inserted into the pipe bore can be used to provide a permanent support for the
PE pipe to prevent creep in the pipe wall under radial compressive forces.
3.7.4
fusion compatibility
