scope:

This European Standard specifies materials and test requirements for tube connections with press fittings made of unalloyed steel. This European Standard specifies press fittings in the size range 12 mm to 108 mm for the purpose of joining unalloyed steel tubes intended for conveying hot or cold water in closed circuits, wet sprinkler systems, oil transporting and compressed air. Permissible operating temperatures and maximum operating pressures are also established. Fittings may comprise a combination of end types, specified in this standard or other standards, providing they are suitable for the fluid /air being conveyed. The standard establishes a designation tube system with press end joints made with the components fitting and tube, pressed with a pressing tool. This European Standard is applicable to press fittings for joining unalloyed steel tubes to EN 10305-3 or EN 10346. Fittings may be suitable for joining other metallic tubes provided the press fitting joint with the specified tube meets the requirements of this standard.
