DIN EN 12735-1
Copper and copper alloys - Seamless, round tubes for air conditioning and refrigeration - Part 1: Tubes for piping systems; German version EN 12735-1:2016
Kupfer und Kupferlegierungen - Nahtlose Rundrohre für die Kälte- und Klimatechnik - Teil 1: Rohre für Leitungssysteme; Deutsche Fassung EN 12735-1:2016
Overview
The standard DIN EN 12735-1 specifies the requirements, sampling, test methods and conditions of delivery for seamless round copper tubes used for refrigeration and air-conditioning piping systems (that is piping, connections, repairs). It is applicable to tubes having an outside diameter from 3 mm up to and including 219 mm. These tubes are supplied in straight lengths in the material conditions hard or half-hard, or in coils in the annealed material condition.
The standard DIN EN 12735-2 specifies the requirements, sampling, test methods and conditions of delivery for seamless round copper tubes, smooth or inner grooved, used for heat exchangers and their internal connecting pipes in the manufacturing of refrigeration and air conditioning equipment.
It is advised to take appropriate precautions if applying insulating material because it could be detrimental to the copper tube.
The European Standard has been prepared by Technical Committee CEN/TC 133 "Copper and copper alloys" (secretariat: DIN). Regarding the German collaboration the responsible committee is Working Committee NA 066-02-03 AA "Kupferrohre (Installation und Industrie)" ("Copper tubes (Installation and industrial)") at FNNE.
