Overview
This standard specifies the requirements, sampling, test methods and conditions of delivery for seamless round copper tubes, smooth or inner finned, used for heat exchangers and their internal connecting pipes in the manufacturing of refrigeration and air conditioning equipment. It is applicable to tubes with an outside diameter from 3,97 mm up to and including 219 mm. The tubes are supplied in straight length in the material conditions hard, half-hard or as coils in the material condition annealed (soft). It is advised to take appropriate precautions if applying insulating material because it could be detrimental to the copper tube. The standard EN 12735-2:2015 has been prepared by Technical Committee CEN/TC 133 "Copper and copper alloys" (secretariat: DIN) of the European Committee for Standardization (CEN). Regarding the German collaboration the responsible committee is NA 066-02-03 AA "Kupferrohre (Installation und Industrie)" ("Copper tubes (Installation and industrial)") at DIN Standards Committee Nonferrous Metals (FNNE).
