This European Standard specifies the requirements, sampling, test methods and conditions of delivery for seamless round copper tubes used for refrigeration and air-conditioning piping systems (i.e. piping, connections, repairs). It is applicable to tubes having an outside diameter from 3 mm up to and including 133 mm. These tubes are supplied in straight lengths in the hard or half-hard material conditions, or in coils in the annealed material condition.
