Plastics piping systems for hot and cold water installations - Crosslinked polyethylene (PE-X) - Part 3: Fittings (ISO 15875-3:2003); German version EN ISO 15875-3:2003
This Part of DIN EN ISO 15875 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 appropriate to the class of application. This standard covers a range of service conditions (application classes) and design pressure classes. It also specifies the test parameters for the test methods referred to in this standard. In conjunction with the other Parts of DIN EN ISO 15875:2003 it is applicable to fittings made from crosslinked polyethylene (PE-X) and to fittings made from other materials which are intended to be fitted to pipes conforming to DIN EN ISO 15875-2:2003 for hot and cold water installations and whereby the joints conform to the requirements of DIN EN ISO 15875-5. This standard is applicable to fittings of the following types: - mechanical fittings; - electrofusion fittings; - fittings with incorporated inserts.#,,#
