This part of EN ISO 15874 specifies the characteristics of pipes made from polypropylene (PP) for 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 operating pressures and temperatures appropriate to the class of application (see Table 1 of EN ISO 15874-1:2003). This standard covers a range of service conditions (application classes), design pressures and pipe dimension classes. For values of T D , T max and T mal in excess of those in Table 1of Part 1, this standard does not apply.
