scope:

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 in the size range 6 mm to 108 mm for the purpose of joining metallic tubes intended for use in hot and cold and combined hot and cold water, heating and cooling systems, natural gas and liquefied petroleum gas systems. Permissible operating temperatures and maximum operating pressures are also established. Fittings may comprise of a combination of end types, specified in this standard, EN 1254 or other standards, providing they are suitable for the fluid /gas being conveyed. The standard establishes a designation system for the fittings. This standard is applicable to press fittings for joining the following tubes: - Copper tubes to EN 1057; - Stainless steel tubes to EN 10312. Fittings may be suitable for joining other metallic tubes provided the press fitting joint with the specified tube meets the requirements of this standard.
