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).

Introduction
This document is a part of a System Standard for piping systems of various materials used for the
rehabilitation of existing pipelines in a specified application area. System Standards for rehabilitation deal
with the following applications:
— ISO 11300: Piping systems for rehabilitation of underground drains, sewers, and water supply networks;
(this standard)
— ISO 11301: Piping systems for rehabilitation of underground gas supply networks.
The System Standards ISO 11300 and ISO 11301 are subdivided into parts covering a specific material per
pipe system.
ISO 11300 is subdivided in four parts:
— Part 1: Polyethylene (PE) material;
— Part 2: Thermoset composite materials;
— Part 3: PVC-U material (this document);
— Part 4: Thermoplastic composite materials.
These System Standards cover various techniques for renovation and trenchless replacement. Furthermore,
they 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 piping system components “as manufactured”.
A consistent structure of clause headings has been adopted for all parts of ISO 11300 and ISO 11301, in order
to facilitate direct comparisons across renovation technique families.
Figure 1 shows the clause structure and the relationship between ISO 11300 and ISO 11301.

For assessment of conformity to the requirements of this document, see ISO/TS 23818-3 .
System Standard ISO 11300 covers the relevant content of and replaces the following previous System
Standards for the rehabilitation of existing drains and sewers:
— The ISO 11296 series: Plastics piping systems for renovation of underground non-pressure drainage and
sewerage networks;
— The ISO 11297 series: Plastics piping systems for renovation of underground drainage and sewerage
networks under pressure;
— The ISO 11298 series: Plastics piping systems for renovation of underground water supply networks;
— The ISO 21225 series: Plastics piping systems for the trenchless replacement of underground pipeline
networks.

networks using plastics pipes, within the scope of pipeline rehabilitation techniques
3.2.1
lining with close-fit pipes
lining with a continuous pipe, of which the cross-section is reduced to facilitate installation and reverted
after installation to provide a close fit to the existing pipe
Note 1 to entry: For the reduction in cross-section, the following are the two options:
— reduction in the pipe manufacturing plant: the pipe is usually supplied coiled on a reel, from which it is directly
inserted;
— reduction on site: the pipe is usually fed through the reduction equipment and simultaneously inserted in one
continuous string.
3.2.2
close fit
situation of the outside of the installed liner relative to the inside of the existing pipeline, which may either
be an interference fit or include a small annular gap resulting from shrinkage and tolerances only
3.2.3

achieve a close fit (3.2.2) to the existing pipeline
