d) irrigation under pressure.
This document is applicable to piping systems intended for the supply of water with a maximum allowable operating pressure (PFA) up to and including 25 bar ). The piping system according to this document is intended for the conveyance of cold water up to and including 45 °C and especially in those applications where special performance requirements are needed, such as impact loads and pressure fluctuations. For temperatures between 25 °C and 45 °C, EN 17176-2:2019, Figure C.1 applies.
This document specifies a range of fittings sizes and pressure classes and gives a requirement and recommendations concerning colours.
NOTE 3 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes.

Introduction
The System Standard, of which this is Part 3, specifies the requirements for a piping system made from
oriented unplasticized poly(vinyl chloride) (PVC-O) pipes and its components. The piping system is
intended to be used for water supply, pressurized drainage, sewerage, treated waste water and
irrigation systems to be used underground or above ground where protected from direct sunlight.
In respect of potential adverse effects on the quality of water intended for human consumption, caused
by the products covered by this document, the following is relevant:
a) This document provides no information as to whether or not the products can be used without
restriction.
b) Existing national regulations concerning the use and/or the characteristics of these products
remain in force.
Requirements and test methods for PVC-O material and components, other than fittings, are specified in
EN 17176-1 and EN 17176-2. For other components (not manufactured from PVC-O) reference is made
to the following standards: EN ISO 1452-3 (PVC-U) and EN 12842 (cast iron). Characteristics for fitness
for purpose (mainly for joints) are specified in EN 17176-5.
This document specifies the characteristics of PVC-O fittings.

Introduction
The System Standard, of which this is Part 3, specifies the requirements for a piping system made from
oriented unplasticized poly(vinyl chloride) (PVC-O) pipes and its components. The piping system is
intended to be used for water supply, pressurized drainage, sewerage, treated waste water and
irrigation systems to be used underground or above ground where protected from direct sunlight.
In respect of potential adverse effects on the quality of water intended for human consumption, caused
by the products covered by this document, the following is relevant:
a) This document provides no information as to whether or not the products can be used without
restriction.
b) Existing national regulations concerning the use and/or the characteristics of these products
remain in force.
Requirements and test methods for PVC-O material and components, other than fittings, are specified in
EN 17176-1 and EN 17176-2. For other components (not manufactured from PVC-O) reference is made
to the following standards: EN ISO 1452-3 (PVC-U) and EN 12842 (cast iron). Characteristics for fitness
for purpose (mainly for joints) are specified in EN 17176-5.
This document specifies the characteristics of PVC-O fittings.

1 Scope
This document specifies the characteristics of solid-wall oriented unplasticized poly(vinyl chloride)
(PVC-O) fittings for piping systems intended for water supply and for buried drainage, sewerage,
treated waste water and irrigation under pressure or above-ground where protected from direct
sunlight. The scope of this document is limited to double sockets, repair couplings, reducers and to non-
end load bearing elbows.
NOTE 1 The scope of this document is restricted to fittings on the market during the preparation of this
document. Therefore, tees, flange adaptors, etc., are excluded from this version of the standard.
NOTE 2 For double sockets, repair couplings and reducers there are no special fittings designs for end-load
bearing applications. However, restrained gaskets can be used for end-load bearing applications. In that case, the
requirements of EN 17176-5 are applicable.
It also specifies the test parameters for the test methods referred to in this document.
In conjunction with EN 17176-1 and EN 17176-5, this document is applicable to oriented PVC-O fittings
intended to be used for the following:
a) water mains and services lines;
b) conveyance of water for both outside and inside buildings;
c) drainage, sewerage and treated waste water under pressure;
d) irrigation under pressure.
This document is applicable to piping systems intended for the supply of water with a maximum
1)
allowable operating pressure (PFA) up to and including 25 bar . The piping system according to this
document is intended for the conveyance of cold water up to and including 45 °C and especially in those
applications where special performance requirements are needed, such as impact loads and pressure
fluctuations. For temperatures between 25 °C and 45 °C, EN 17176-2:2019, Figure C.1 applies.
This document specifies a range of fittings sizes and pressure classes and gives a requirement and
recommendations concerning colours.
NOTE 3 It is the responsibility of the purchaser or specifier to make the appropriate selections from these
aspects, taking into account their particular requirements and any relevant national regulations and installation
practices or codes.
