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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to the

This document was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for
the transport of fluids, SC 8, Rehabilitation of pipeline systems.
This second edition cancels and replaces the first edition (ISO 11298-3:2010), which has been
technically revised.
The main changes compared to the previous edition are as follows:
— Figure 1 and Clauses 1, 3.4, 3.6, 5.8, 8.4, 8.5 and 9.3 to 9.8 have been technically revised.
— New sub-clauses 5.9, 6.3 and 8.9 specifying regional requirements for pipes, fittings and the installed
lining system respectively, have also been added in accordance with the Vienna Agreement, to allow
reference to European standards in countries where these are mandated by law in place of ISO
standards of identical scope.

Introduction
This document is a part of a System Standard for plastics piping systems of various materials used for
the renovation of existing pipelines in a specified application area. System Standards for renovation
deal with the following applications:
— ISO 11296, Plastics piping systems for renovation of underground non-pressure drainage and sewerage
networks;
— ISO 11297, Plastics piping systems for renovation of underground drainage and sewerage networks
under pressure;
— ISO 11298, Plastics piping systems for renovation of underground water supply networks (this
document);
— ISO 11299, 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 systems components “as
manufactured”.
Each of the System Standards comprises a:
— Part 1: General
and all applicable renovation technique family-related parts, which for water supply networks include
or potentially include the following:
— Part 2: Lining with continuous pipes
— Part 3: Lining with close-fit pipes (this document)
— Part 4: Lining with cured-in-place pipes
— Part 5: Lining with discrete pipes
— Part 6: Lining with adhesive-backed hoses
— Part 10: Lining with sprayed polymeric materials
— Part 11: Lining with inserted hoses
The requirements for any given renovation technique family are specified in Part 1, applied in
conjunction with the relevant other part. For example, ISO 11298-1 and this document 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 11298, in order to
facilitate direct comparisons across renovation technique families.
Figure 1 shows the common part and clause structure and the relationship between ISO 11298 and the
System Standards for other application areas.

Plastics piping systems for renovation of underground
water supply networks —
Part 3:
Lining with close-fit pipes
1 Scope
This document, in conjunction with ISO 11298-1, specifies requirements and test methods for close-fit
lining systems intended to be used for the renovation of water supply networks, which transport water
intended for human consumption, including raw water intake pipelines.
It applies to pipes and fittings, as manufactured, as well as to the installed lining system. It is applicable
to polyethylene (PE) pipes of either solid wall single layer or co-extruded layer construction, which is
reduced in the factory or on site to provide a close-fitting independent or interactive pressure pipe liner,
as well as associated fittings and joints for the construction of the lining system. It is not applicable to
PE coated pipes having a peelable, contiguous, thermoplastic additional layer on the outside of the pipe.
It is applicable to PE pipes, fittings and assemblies intended to be used at an operating temperature of
20 °C as the reference temperature.
NOTE For applications operating at constant temperatures greater than 20 °C and up to 40 °C, see
ISO 4427-1:2007, Annex A.
