Over deze norm
This Part of ISO 15874 specifies the characteristics of fittings for polypropylene (PP) 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 of ISO 15874-1). This standard covers a range of service conditions (application classes) and design pressure classes. For values of TD, Tmax and Tmal in excess of those in Table 1 of Part 1of this standard does not apply. It also specifies the parameters for the test methods referred to in this standard. In conjunction with the other parts of ISO 15874 (see Foreword) it is applicable to fittings made from PP and to fittings made from other materials which are intended to be fitted to pipes conforming to ISO 15874-2 for hot and cold water installations and whereby the joints conform to the requirements of ISO 15874-5. It is also applicable to fittings made from alternative materials which when fitted to pipes conforming to Part 2, conform to the requirements of Part 5 of ISO 15874. This standard is applicable to fittings of the following types: - socket fusion fittings - electrofusion fittings - mechanical fittings - fittings with incorporated inserts. It is also applicable to fittings made from alternative materials which when fitted to pipes conforming to ISO 15874-2, conform to the requirements of ISO 15874-5.
