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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see the following
URL: www .iso .org/iso/foreword .html.
This document was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for
the transport of fluids, Subcommittee SC 6, Reinforced plastics pipes and fittings for all applications.
This second edition cancels and replaces the first edition (ISO 10467:2004), which has been technically
revised. It also incorporates the Amendment ISO 10467:2004/Amd. 1:2012.
The main changes compared to the previous edition are as follows:
— inclusion of a guidance for the harmonization of design practices which are based on a partial safety
factor concept and risk management engineering, as well as inclusion of the probability of failure
and possible consequences of failures;
— addition of references to the general principle for the reliability of structures detailed in ISO 2394
and EN 1990;
— addition of a new safety factor concept for the hydrostatic pressure design;
— addition of a clear reference for assessment of conformity;
— changes in Clause 6, including pressure tests requirements for fittings;
— changes in Clause 7;
— changes in Annex A for the establishment of the design requirements.

INTERNATIONAL STANDARD ISO 10467:2018(E)
Plastics piping systems for pressure and non-pressure
drainage and sewerage — Glass-reinforced thermosetting
plastics (GRP) systems based on unsaturated polyester
(UP) resin
1 Scope
This document specifies the properties of piping system components made from glass-reinforced
thermosetting plastics (GRP) based on unsaturated polyester resin (UP). It is suited for all types of
drainage and sewerage with or without pressure. This document is applicable to GRP UP piping systems,
with flexible or rigid joints with or without end thrust load-bearing capability, primarily intended for
use in direct buried installations.
NOTE 1 For the purpose of this document, the term polyester resin (UP) also includes vinyl-ester resins (VE).
NOTE 2 Piping systems conforming to this document can also be used for non-buried applications, provided
the influence of the environment and the supports are considered in the design of the pipes, fittings and joints.
NOTE 3 This document can also apply for other installations, such as slip-lining rehabilitation of existing pipes.
NOTE 4 This document is also referenced in ISO 25780, which specifies requirements for GRP-pipes used for
jacking installation.
The requirements for the hydrostatic pressure design of pipes referring to this document meet the
requirements of ISO/TS 20656-1 and the general principle for the reliability of structures detailed in
ISO 2394 and in EN 1990. These International Standards provide procedures for the harmonization of
design practices and address the probability of failure, as well as possible consequences of failures. The
design practices are based on a partial safety factor concept, as well as on risk management engineering.
This document is applicable to pipes, fittings and their joints of nominal sizes from DN 50 to DN 4000
which are intended to be used for the conveyance of water at temperatures up to 50 °C, with or without
pressure. In a pipework system, pipes and fittings of different nominal pressure and stiffness ratings
may be used together. Clause 4 specifies the general aspects of GRP UP piping systems intended to be
used in the field of drainage or sewerage with or without pressure.
Clause 5 specifies the characteristics of pipes made from GRP UP with or without aggregates and/or
fillers. The pipes may have a thermoplastics or thermosetting resin liner. Clause 5 also specifies the test
parameters for the test methods referred to in this document.
Clause 6 specifies the characteristics of fittings made from GRP UP, with or without a thermoplastics or
thermosetting resin liner, intended to be used in the field of drainage and sewerage. Clause 6 specifies
the dimensional and performance requirements for bends, branches, reducers, saddles and flanged
adaptors. Clause 6 covers requirements to prove the structural design of fittings. It is applicable to
fittings made using any of the following techniques:
— fabrication from straight pipes;
— moulding by
1) filament winding,
2) tape winding,
3) contact moulding, and
4) hot or cold compression moulding.

Clause 7 is applicable to the joints to be used in GRP UP piping systems to be used for the conveyance of
surface water and sewerage, both buried and non-buried. It covers requirements to prove the design of
the joint. Clause 7 specifies type test performance requirements for the following joints as a function of
the declared nominal pressure rating of the pipeline or system:
a) socket-and-spigot (including double-socket) joints or mechanical joints;
b) locked socket-and-spigot joints;
c) cemented or wrapped joints;
d) bolted flange joints.
