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.

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.

ISO 11296-3:2009(E) iv © ISO 2009 – All rights reserved 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. kSIST FprEN ISO 11296-3:2010
ISO 11296-3:2009(E) © ISO 2009 – All rights reserved v 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. kSIST FprEN ISO 11296-3:2010
