Introduction
This document is a part of a system standard for plastics piping systems of various materials used for
renovation of existing pipelines in a specified application area. System standards for renovation 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;
— 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 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, which for water supply networks include
or potentially include the following:
— Part 2: Lining with continuous pipes;
— Part 3: Lining with close-fit pipes;
— Part 4: Lining with cured-in-place pipes (this document);
— 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 given in Part 1 applied in conjunction
with the other relevant part. For example, both ISO 11298-1 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 11298 and the system
standards for other application areas.

DRAFT INTERNATIONAL STANDARD ISO/DIS 11298-4:2019(E)
Plastics piping systems for renovation of underground
water supply networks —
Part 4:
Lining with cured-in-place pipes
1 Scope
This document, in conjunction with ISO 11298-1, specifies requirements and test methods for cured-
in-place pipes and fittings used for the renovation of water supply networks which transport water
intended for human consumption, including raw water intake pipelines.
It applies to independent (fully structural, class A) and interactive (semi structural, class B) pressure
pipe liners, as defined in ISO 11295, which do not rely on adhesion to the existing pipeline. It applies
to the use of various thermosetting resin systems, in combination with compatible fibrous carrier
materials, reinforcement, and other process-related plastics components (see 5.1).
It does not include requirements or test methods for resistance to cyclic loading or the pressure rating
of CIPP liners where passing through bends, which are outside the scope of this document.
It is applicable to cured-in-place pipe lining systems intended to be used at a service temperature of up
to 25 °C.
NOTE For applications operating at service temperatures greater than 25 °C guidance on re-rating factors
can be supplied by the system supplier.
