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 11299-3 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the
transport of fluids.
ISO 11299 consists of the following parts, under the general title Plastics piping systems for renovation of
underground gas supply networks:

—  Part 3: Lining with close-fit pipes

Introduction
This part of ISO 11299 is 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 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 (this application).
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 verification of characteristics of plastics piping systems as manufactured.
This system standard comprises a Part 1: General and all applicable parts relating to the renovation technique
family, from 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 6: Lining with adhesive-backed hoses
The requirements for any given renovation technique family are specified in this part of ISO 11299 and are
applied in conjunction with the relevant other part. For example, both ISO 11299-1 and this part of ISO 11299
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 11299, in order to facilitate
direct comparisons across renovation technique families.
Figure 1 illustrates the common part and clause structure and the relationship between ISO 11299 and the
system standards for other application areas.

Part 3:
Lining with close-fit pipes
1 Scope
This part of ISO 11299, in conjunction with ISO 11299-1, specifies requirements and test methods for close-fit
lining systems intended to be used for the renovation of gas supply networks.
It is applicable to polyethylene (PE) pipes for both independent and interactive pressure pipe liners as well as
associated fittings and joints for the construction of the lining system.

3.7 Joints
3.7.1
electrofusion joint
joint between a PE socket or saddle electrofusion fitting and a pipe or fitting with spigotted ends, made by
heating the electrofusion fittings by the Joule effect of the heating element incorporated at their jointing
surfaces, causing the material adjacent to them to melt and pipe and fitting surfaces to fuse
3.7.2
butt fusion joint
joint made by heating the planed ends of matching surfaces by holding them against a flat heating plate until
the PE material reaches fusion temperature, quickly removing the heating plate and pushing the two softened
ends against one another
3.7.3
mechanical joint
joint made by assembling a PE pipe to another PE pipe, or any other element of the piping system that generally
includes a compression part, to provide for pressure integrity, leaktightness and resistance to end loads
NOTE  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.
