This document specifies the characteristics of fittings for 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 ISO 15875-1). It also specifies the test parameters for the test methods referred to in this standard. The designation crosslinked polyethylene is used together with the abbreviation PE-X throughout ISO 15875, including this document. ISO 15875 covers a range of service conditions (application classes) and design pressure classes. For values of design temperature (TD), maximum temperature (Tmax) and malfunction temperature (Tmal) and service times in excess of those defined in ISO 15875-1, this document does not apply. NOTE 1 – It is the responsibility of the purchaser or specifier to make the appropriate selections from these application classes (see ISO 15875 part 1), taking into account their particular requirements and any relevant national regulations and installation practices or codes.
