Overview
CEN/TS 17176-3:2022 specifies the characteristics and test parameters for solid-wall oriented unplasticized poly(vinyl chloride) (PVC‑O) fittings used in plastics piping systems for water supply, buried and above‑ground drainage, sewerage, treated waste water and irrigation under pressure. This Technical Specification covers a defined set of fittings - double sockets, repair couplings, reducers and non‑end load bearing elbows - for systems with a maximum allowable operating pressure (PFA) up to 25 bar and conveyance of cold water up to 45 °C. The document is part of the EN 17176 PVC‑O series and includes geometric, material, mechanical and marking requirements plus the test parameters for referenced methods.
Key topics and requirements
- Scope limits: Only fittings that were on the market during preparation are included; tees and flange adaptors are excluded in this edition.
- Materials and orientation: Requirements for PVC‑O material, including density and circumferential orientation factor, to ensure mechanical performance.
- Geometrical characteristics: Design lengths, bend radii, nominal outside diameters and minimum wall thickness for specified fittings.
- Pressure and temperature: Selection rules for nominal pressure up to 25 bar; applicability to cold water services up to 45 °C (with EN 17176‑2 guidance between 25 °C and 45 °C).
- Mechanical performance: Resistance to long‑term hydrostatic pressure (long‑term hydrostatic strength) and performance under impact loads and pressure fluctuations.
- Sealing and joints: Requirements for sealing rings and use of restrained gaskets for end‑load bearing applications (when EN 17176‑5 applies).
- Testing and test parameters: Test procedures and reporting requirements (see Annexes A and B for hydrostatic strength and orientation factor tests).
- Marking and colour: Minimum marking requirements and colour recommendations to aid identification and installation.
Applications

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
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.

The SIST-TS CEN/TS 17176-3:2022 standard provides a comprehensive framework for the characteristics and testing of solid-wall oriented unplasticized poly(vinyl chloride) (PVC-O) fittings within piping systems designed for water supply and drainage applications. Its scope is clearly defined, focusing on essential fittings such as double sockets, repair couplings, reducers, and non-end load bearing elbows. One of the notable strengths of this standard is its thorough specification of the test parameters and methods applicable to PVC-O fittings. This aspect is crucial for ensuring reliable performance in various applications, including water mains, drainage, sewerage, and irrigation systems operating under pressure. The standard addresses the specific operational context by accommodating use cases where impact loads and pressure fluctuations may occur, thus enhancing the durability and resilience of the fittings. Moreover, the inclusion of pressure classes and fitting sizes reflects the standard's commitment to versatility and applicability across a range of situations. By allowing for a maximum allowable operating pressure (PFA) of up to and including 25 bar, the standard proves relevant for both residential and commercial water conveyance, emphasizing its broad utility in the construction and infrastructure sectors. The attention to detail regarding temperature limits, recommending cold water conveyance up to 45 °C and referencing EN 17176-2:2019 for specific thermal applications, further demonstrates the standard's alignment with practical industry needs. It also recognizes the importance of color specifications, ensuring that users can select fittings that align with aesthetic and functional requirements. In conclusion, SIST-TS CEN/TS 17176-3:2022 stands as a significant reference point for manufacturers, engineers, and specifiers involved in the design and implementation of PVC-O piping systems for water supply, drainage, and irrigation. Its focused scope, robust testing requirements, and practical guidance make it a pivotal standard in the ongoing development of reliable and efficient plastic piping solutions.
