scope:

This European Standard specifies materials and test requirements for tube connections with press fittings made of stainless steel. This European Standard specifies press fittings in the size range 12 mm to 108 mm for the purpose of joining stainless steel tubes intended for use in hot or cold or combined hot and cold water, heating and cooling systems, also for natural gas and liquefied petroleum gas systems with maximal operating pressure up to 1 bar. 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 /gas 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 standard is applicable to press fittings for joining stainless steel tubes according to EN 10312 and to EN 10217-7. Fittings may be suitable for joining other metallic tubes provided the press fitting joint with the specified tube meets the requirements of this standard.
