Project No.prEN 1254-4 rev
TitleThis European Standard specifies requirements, assessment methods, compliance criteria and a designation system for threaded fittings. These threaded ends exist with metallic and with non-metallic sealing elements for the purposes of joining with tubes, pipes, fittings or valves, the threaded ends have a size range from 3,175 mm (1/8”) to 101,6 mm (4”). The threaded fittings are designed for a service lifetime up to fifty years. This European Standard applies to fittings made of materials listed in CEN/TS 13388. Threaded fittings may also have flanged end connections according to EN 1092-3. Threaded fittings may also have a plated or other decorative surface coating. Products covered by this standard are intended to be used in: a) liquid applications:  hot or cold or combined hot and cold water systems;  heating and cooling systems;  drainage systems;  sprinkler systems. b) gas applications:  natural gas and liquefied petroleum gas systems with a maximum operating pressure less than or equal to 5 bar;  compressed air. Operating temperatures and pressures for assembled joints shall not exceed the values in Annex A.
