This European Standard specifies materials, assembly dimensions and tolerances and test requirements for fittings of copper and copper alloys with or without plating or coating. Maximum permissible temperatures and pressures are also established. This part of EN 1254 specifies connection end dimensions for other than capillary or compression ends, for fittings combining capillary and/or compression ends with other types of connecting ends.
