This document specifies the requirements and test methods for plastics piping systems intended to be
used for the renovation of underground water supply networks. It is applicable to pipes and fittings, as
manufactured, as well as to the installed lining system. It is not applicable to the existing pipeline or
any non-structural sprayed coatings or annular filler.

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

on the ISO list of patent declarations received (see www .iso .org/ patents).

constitute an endorsement.

Introduction

This document is a 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:

— 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 by the requirement to verify 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 (this document)

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;
— 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 specified in Part 1, applied in

conjunction with the relevant other part. For example, this document and ISO 11298-3 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 11298, in order to

facilitate direct comparisons across renovation technique families.

Figure 1 shows the common part and clause structure and the relationship between ISO 11298 and the

System Standards for other application areas.
