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 11298-3 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the
transport of fluids.
ISO 11298 consists of the following parts, under the general title Plastics piping systems for renovation of
underground water supply networks:
⎯ Part 1: General
⎯ Part 3: Lining with close-fit pipes
Lining with continuous pipes is to form the subject of a part 2; lining with cured-in-place pipes is to form the
subject of a part 4; lining with adhesive-backed hoses is to form the subject of a part 6.

ISO 11298-3:2010(E)
Introduction
This part of ISO 11298 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:
⎯ Plastics piping systems for renovation of underground non-pressure drainage and sewerage networks;
⎯ Plastics piping systems for renovation of underground water supply networks;
⎯ Plastics piping systems for renovation of underground gas supply networks;
⎯ Plastics piping systems for renovation of underground drainage and sewerage networks under pressure.
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.
This System Standard 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 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, ISO 11298-1 and this part of ISO 11298 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 part of ISO 11298, 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 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.
