NOTE It is advised to take appropriate precautions if applying insulating material because it could be detri-mental to the tube. BS EN
30、 12735-1:2016EN 12735-1:2016 (E) 7 1 Scope 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 ap
31、plicable 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 straigh
32、t length in the material conditions hard or annealed. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are in-dispensable for its application.
