|Publication Date:||1 June 2016|
|ICS Code (Non-ferrous metal pipes):||23.040.15|
This European Standard specifies the requirements, sampling, test methods and conditions of delivery for seamless round copper and copper alloy tubes used for refrigeration and air-conditioning piping systems (i.e. piping, connections and repairs).
It is applicable to tubes with an outside diameter from 3 mm up to and including 219 mm.
Tubes made of the copper-grade Cu-DHP are supplied in straight lengths in the material conditions hard or half-hard, or in coils in the annealed material condition.
Tubes made of the alloy CuFe2P are supplied in straight length in the material conditions hard or annealed.
