Plastics piping systems for hot and cold water installations - Crosslinked polyethylene (PE-X) - Part 1: General (ISO 15875-1:2025)

This document specifies the general aspects of crosslinked polyethylene (PE-X) piping systems intended to be used for hot and cold water installations within buildings for the conveyance of water, whether or not intended for human consumption (domestic systems), and for heating systems, under design pressures and temperatures according to the class of application (see Table 1). This document also specifies the basis for the test parameters for the test methods referred to in the ISO 15875 series. This document covers a range of service conditions (application classes), design pressures and pipe dimension classes. The ISO 15875 series does not apply to values of design temperature (TD), maximum temperature (Tmax) and malfunction temperature (Tmal), as well as service times in excess of those defined in Table 1.
