This European Standard specifies materials and test requirements for fittings of copper and copper alloys.
This part of EN 1254 specifies press end connections with or without plating or coating in the size range 10 mm to 110 mm for the purpose of joining plastics and multilayer pipes for use in hot and cold water systems according to EN 806, which are designed for service lifetime up to fifty years, as well as heating and cooling systems or gas systems, including fuel gas systems.
Fittings may comprise a combination of end types, specified in this European Standard, EN 1254, or other standards, providing they are suitable for the fluid / gas being conveyed.
The European Standard establishes a designation system for the fittings.
This European Standard is applicable to press fittings for joining the following plastics and multilayer pipes:
EN ISO 15874, Plastics piping systems for hot and cold water installations — Polypropylene (PP);
EN ISO 15875, Plastics piping systems for hot and cold water installations — Crosslinked polyethylene (PE-X);
EN ISO 15876, Plastics piping systems for hot and cold water installations — Polybutylene (PB);
EN ISO 15877, Plastics piping systems for hot and cold water installations — Chlorinated poly (vinyl chloride) (PVC-C);
EN ISO 21003, Multilayer piping systems for hot and cold water installations inside buildings;
EN ISO 22391, Plastics piping systems for hot and cold water installations — Polyethylene of raised temperature resistance (PE-RT);
ISO 17484, Plastics piping systems — Multilayer pipe systems for indoor gas installations with a maximum operating pressure up to and including 5 bar (500 kPa).
Fittings may be suitable for joining other pipes provided the fitting joint with the specified pipe meets the requirements of this European Standard and the relevant pipe standard.
