Introduction
The ISO 15875 series specifies the requirements for a piping system consisting of pipe, fitting and the
jointing made of it, when the pipe is made from crosslinked polyethylene (PE-X). The ISO ISO 15875 series
consists ISO 15875-1, ISO 15875-2, ISO 15875-3 and ISO 15875-5, and covers the requirements and related
test methods for all components used in the system (e. g. pipes and fittings). In addition, the ISO 15875 series
includes requirements and related test methods to verify the performance and compatibility of the jointing
of components.
The piping system is intended to be used for hot and cold water installations.
In respect of potential adverse effects on the quality of water intended for human consumption, caused by
the product covered by the ISO 15875 series:
— ISO 15875 series provides no information as to whether the product may be used without restriction in
any of the Member States of the EU or EFTA;
— it should be noted that, while awaiting the adoption of verifiable European criteria, existing national
regulations concerning the use and/or the characteristics of this product remain in force.
Requirements and test methods for material and components of the piping system are specified in
ISO 15875-1, ISO 15875-2 and ISO 15875-3. ISO/TS 15875-7 gives guidance for the assessment of conformity.
This document specifies the characteristics of fitness for purpose of the piping systems.
At the date of publication of this document, standards for piping systems of other plastics materials used for
the same application include:
— the ISO 15874 series,
— the ISO 15875 series,
— the ISO 15876 series,
— the ISO 15877 series,
— the ISO 21003 series, and
— the ISO 22391 series.

Introduction
La série ISO 15875 spécifie les exigences pour un système de canalisations composé de tubes, de raccords et
de leur assemblage lorsque le tube est fabriqué en polyéthylène réticulé (PE-X). La série ISO 15875 comprend
l’ISO 15875-1, l’ISO 15875-2, l’ISO 15875-3 et l’ISO 15875-5 et couvre les exigences et les méthodes d'essai
associées pour tous les composants utilisés dans le système (par exemple, les tubes et les raccords). En outre,
la série ISO 15875 comprend les exigences et les méthodes d'essai associées pour vérifier les performances
et la compatibilité de l'assemblage des composants.
Le système de canalisations est destiné aux installations d'eau chaude et froide.
Pour tenir compte des éventuels effets défavorables sur la qualité de l’eau destinée à la consommation
humaine, causés par le produit relevant de la série ISO 15875:
— la série ISO 15875 ne fournit pas d’information sur les possibles restrictions d’utilisation du produit dans
chacun des états membres de l’UE ou de l’EFTA;
— il convient de noter que, dans l’attente de l’adoption de critères européens vérifiables, les réglementations
nationales existantes relatives à l’utilisation et/ou aux caractéristiques des produits restent en vigueur.
Les exigences et les méthodes d'essai pour la matière et les composants, autres que des raccords, sont
spécifiées dans l’ISO 15875-1, l’ISO 15875-2 et l’ISO 15875-3. L’ISO/TS 15875-7 donne un guide pour
l'évaluation de la conformité.
Le présent document spécifie les caractéristiques d’aptitude à l’emploi des systèmes de canalisation.
À la date de publication du présent document, les normes de systèmes pour les systèmes de canalisations en
d'autres matières plastiques utilisées pour la même application comprennent:
— la série ISO 15874,
— la série ISO 15875,
— la série ISO 15876,
— la série ISO 15877,
— la série ISO 21003, et
— la série ISO 22391.
