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 pipe systems of distinctive
materials are applicable:
ISO/TS 23818-1, 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;
ISO/TS 23818-3 (this document), Assessment of conformity of plastics piping systems for the rehabilitation
of existing pipelines — Part 3: Unplasticized poly (vinyl chloride) (PVC-U) material.
These three documents cover the system standards, as presented in Table 1.

The format of the three Technical Specifications is in line with Technical Specifications for assessment of
conformity to other system standards, apart from presenting the detailed requirements for Inspection
and Testing in two annexes, for non-pressure applications and pressure applications (where applicable)
respectively. For this document, covering only non-pressure applications, the format is schematically
represented in Figure 1.
Figure 1 — Format of the Technical Specifications for conformity assessment
Figures 2 and 3 are intended to provide general information on the concept of testing and organization
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.

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 pipe systems of distinctive
materials are applicable:
ISO/TS 23818-1, 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;
ISO/TS 23818-3 (this document), Assessment of conformity of plastics piping systems for the rehabilitation
of existing pipelines — Part 3: Unplasticized poly (vinyl chloride) (PVC-U) material.
These three documents cover the system standards, as presented in Table 1.

5 General
Materials, products, joints and assemblies shall conform to the requirements given in applicable parts
of ISO 11296.
Where these product standards include clauses entitled ‘Regional requirements’, in countries of the
single European market, conformity shall be assessed against certain different normative references
(EN equivalents of ISO standards where not yet merged as EN/ISO standards), as specified in the
product standards.
Products and assemblies shall be produced by the manufacturer under a quality management system
which includes a quality plan.
It is recommended that the quality management system conforms to ISO 9001 or a similar
management system.
The production of representative “I” stage samples for type testing shall conform to the requirements
given in ISO 11296-1.

6.1 Grouping
6.1.1 General
For the purposes of this document, the groups specified in 6.1.2 and 6.1.3 apply.
6.1.2 Size groups
Five size groups are defined for pipes and fittings, as given in Table 2.
For testing purposes, one individual nominal diameter, d , shall be selected from each group.

6.2 Type testing
Relevant type tests shall be carried out on every new system and whenever there is a change in design,
material, production or installation method, other than routine in-process adjustments, and whenever
there is an extension of the product range.
Type tests to be carried out when there is a change of the production site, depend on the extent of the
change, and should therefore be defined individually by the manufacturer and certification body.
Other change conditions characteristics to be type tested and sampling procedures are specified in:
— A.1, TT for products applied to underground non-pressure drainage and sewerage networks.
The following abbreviated terms are used to identify change conditions requiring new type testing in
the respective tables of Annex A1.
N : new system;
D : change in design;
M : change of material;
E : extension of the product range.
The detailed specifications of these change conditions provided in Annex B shall be observed.
6.3 Batch release tests
Characteristics to be batch release tested and sampling procedures are specified in:
— A.2, BRT for products applied to underground non-pressure drainage and sewerage networks.
6.4 Process verification tests
Process verification tests include tests conducted at the “M” stage (PVT) and, where applicable, tests
carried out at the “I” stage (PVT-I).
If a sample or process parameter does not conform to the requirements of the installation process
given in applicable parts of ISO 11296 or ISO 4435, the relevant retest procedure detailed in the
manufacturer’s quality plan should be performed.
For countries of the single European Market, ISO 4435 is replaced by EN 1401-1.
NOTE Failure to meet the required installation process parameters does not necessarily preclude successful
installation.
Characteristics to be process verification tested and sampling procedures are specified in:
— A.3, PVT and
