DIN EN 12735-1:2016-11 EN 12735-1:2016 (E) 6 Introduction It is recommended that tubes manufactured to this European Standard are certified as conforming to the requirements of this standard based on continuing surveillance which should be coupled with an assessment
32、of a suppliers quality management system such as EN ISO 9001. NOTE It is advised to take appropriate precautions if applying insulating material because it could be detri-mental to the tube. DIN EN 12735-1:2016-11 EN 12735-1:2016 (E) 7 1 Scope This European Standard specifies the requirements, sampl
33、ing, 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
34、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. 2 Normative references The following document
