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

This second edition cancels and replaces the first edition (ISO 11296-4:2009), which has been
technically revised.
The main changes compared to the previous edition are as follows:
— the service temperature range has been explicitly stated in the scope;
— in Clause 3, new definitions have been added for temporary, permanent and semi-permanent
membranes, with Annex A and the definition of preliner updated accordingly; for nominal wall
thickness specialized for CIPP; and for service temperature and type testing adopted from other
standards;
— type “R” and “E-CR” glass fibres have been added to Table 1;
— the requirements on “M” stage strength characteristics of the neat resin system have been removed
in Table 2, as they have been effectively covered in Table 5 by the “I” stage requirements on
mechanical characteristics of the cured composite;
— new requirements for the nature of the bond of any semi-permanent internal membrane to the
underlying composite, and for declaration of class of composite in accordance with ISO 14125, have
been added in 8.1;
— a new subclause has been added to 8.5 to specify reference temperature for testing, and procedure
for determining temperature re-rating factors where required;
— separate tables for short and long-term mechanical characteristics have been created in 8.5, and
minima for declared values removed except for ring stiffness, strain capacity and creep factor;

ISO 11296-4:2018(E)
— the following have been added to Table 6:
a) option of ring test for wet creep factor;
b) test for long-term flexural strength under dry or wet conditions by the method detailed in the
new Annex D;
— a test for stress corrosion (new Annex D test in acid environment) has been added to Table 7;
— further requirements for documenting specific installation parameters and procedures, and the
related environmental precautions, in the installation manual for each individual CIPP technique,
have been added in 9.4;
— requirements for documentation in the installation manual of technique-specific methods for
sealing liner connections at manholes and laterals have been added in 9.7;
— Annex B has been revised to relax curvature restriction on 3-point bend test samples, and to
include a full new procedure for calculation and reporting of test results without partial reference
to ISO 178;
— the previous Annexes C and D has been merged into a single new Annex C specifying a common
procedure for determination of long-term modulus under either dry or wet conditions.

ISO 11296-4:2018(E)
Introduction
System standards dealing with the following applications are either available or in preparation:
— ISO 11296, Plastics piping systems for renovation of underground non-pressure drainage and sewerage
networks (this document);
— 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;
— 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 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”.
This document (system standard) 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 7: Lining with spirally-wound pipes;
— Part 8: Lining with pipe segments;
— Part 9: Lining with a rigidly anchored plastics inner layer;
— Part 10: Lining with sprayed polymeric materials.
The requirements for any given renovation technique family are given in ISO 11296-1 applied in
conjunction with the other relevant parts. For example, both ISO 11296-1 and this document together
specify the requirements relating to lining with cured-in-place 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 shows the common structure and the relationship between ISO 11296 and the system
standards for other application areas.

5.7 Jointing
The lining tube after impregnation shall be provided in lengths such that no jointing is required
between points of access to the sewer.
5.8 Marking
The marking shall conform to ISO 11296-1:2018, 5.8. It shall be applied to the outside of the lining tube
as delivered to the installation site or in the case of pre-packaged lining tubes, on the outside of the
packaging.
For compliance with ISO 11296-1:2018, 5.8 c), the dimension marked shall be the nominal outside
diameter or, in the case of lining tubes to be installed in non-circular sewers, the diameter of the circle
having the same outside perimeter as the lining tube.
For compliance with ISO 11296-1:2018, 5.8 d), the dimension marked shall be the nominal CIPP wall
thickness.
For compliance with ISO 11296-1:2018, 5.8 f), the manufacturer's information shall enable the
identification of the lining tube structure and (if pre-impregnated) the resin system used.
6 Fittings at the “M” stage
NOTE This clause describes the various materials which a cured-in-place fitting conforming to this
document can comprise, and specifies requirements relating to those materials and intermediate fabrications at
the “M” stage. For “I” stage requirements, see Clause 8.
6.1 Materials
The only cured-in-place fittings covered by this document are lateral connection collars. Such collars
can be an integral part of a complete lining of a lateral pipe. External saddle connections between cured-
in-place main pipes and lateral pipes can also be made with standard thermoplastic or GRP fittings.
Lateral connection collars shall comprise cured-in-place components conforming to 5.1, but may also
include additional thermoplastic components of declared composition.
External saddles shall be of PP, PVC-U or GRP-UP, conforming to ISO 4435, ISO 8773 or EN 14364:2013, 6.5,
as applicable.
6.2 General characteristics
No general requirements apply.
6.3 Material characteristics
The resin system of cured-in-place fittings shall conform to 5.3.
6.4 Geometric characteristics
Cured-in-place lateral connection collars shall be classified, as indicated in Table 3, according to the
minimum distance extended into the lateral pipe.
ISO 11296-4:2018(E)
Table 3 — Classification of cured-in-place lateral connection collars
a
Class Minimum extension into lateral pipe
A 1 000 mm
B 400 mm and at least 150 mm beyond first joint in existing lateral pipe
C 100 mm
a
This classification applies where the diameter of the lateral pipe is less than or equal to DN 200.
In addition, the rim of any cured-in-place lateral connection collar shall overlap the main pipe by not
less than 50 mm (see Figure 3).
