Plastics piping systems for pressure and non-pressure drainage and sewerage -- Glass-reinforced thermosetting plastics (GRP) systems based on unsaturated polyester (UP) resin

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 filament winding, tape winding, contact moulding, and 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.

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).

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
