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
System standards dealing with the following applications are either available or in preparation for
pipeline rehabilitation:
— 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;
— ISO 11299, Plastics piping systems for renovation of underground gas supply networks;
— ISO 21225, Plastics piping systems for the trenchless replacement of underground pipeline 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.
For the assessment of conformity, three Technical Specifications for pipes of distinct materials are
applicable:
— ISO/TS 23818-1 (this document), Assessment of conformity of plastics piping systems for the
rehabilitation of existing pipelines — Part 1: Polyethylene (PE) material;
1)
— ISO/TS 23818-2 , Assessment of conformity of plastics piping systems for the rehabilitation of existing
pipelines — Part 2: Resin-fibre composite (RFC) material;
2)
— ISO/TS 23818-3 , Assessment of conformity of plastics piping systems for the rehabilitation of existing
pipelines — Part 3: Unplasticized poly(vinyl chloride) (PVC-U) material.
These three Technical Specifications cover the system standards, as presented in Table 1.

Figures 2 and 3 are intended to provide general information on the concept of testing and organisation
of those tests used for the purpose of the assessment of conformity. For each type of test, i.e. type testing

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.

Introduction
System standards dealing with the following applications are either available or in preparation for
pipeline rehabilitation:
— 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;
— ISO 11299, Plastics piping systems for renovation of underground gas supply networks;
— ISO 21225, Plastics piping systems for the trenchless replacement of underground pipeline 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.
For the assessment of conformity, three Technical Specifications for pipes of distinct materials are
applicable:
— ISO/TS 23818-1 (this document), Assessment of conformity of plastics piping systems for the
rehabilitation of existing pipelines — Part 1: Polyethylene (PE) material;
1)
— ISO/TS 23818-2 , Assessment of conformity of plastics piping systems for the rehabilitation of existing
pipelines — Part 2: Resin-fibre composite (RFC) material;
2)
— ISO/TS 23818-3 , Assessment of conformity of plastics piping systems for the rehabilitation of existing
pipelines — Part 3: Unplasticized poly(vinyl chloride) (PVC-U) material.
These three Technical Specifications cover the system standards, as presented in Table 1.
1) Under preparation. Stage at the time of publication: ISO/WD TS 23818-2:2020.

respectively.
The format is schematically represented in Figure 1.

Figures 2 and 3 are intended to provide general information on the concept of testing and organisation
of those tests used for the purpose of the assessment of conformity. For each type of test, i.e. type testing
(TT), batch release test (BRT), process verification test (PVT), and audit test (AT), this document details
the applicable characteristics to be assessed as well as the frequency and sampling of testing.
