FprEN 12735-1:2015 (E) 4 European foreword This document (FprEN 12735-1:2015) has been prepared by Technical Committee CEN/TC 133 “Copper and copper alloys”, the secretariat of which is held by DIN. This document is currently submitted to the Unique Acceptance Procedure. This document will supersede EN 12735-1:2010. This document has been prepared under a mandate given to CEN by the European Commission and the Eu-ropean Free Trade Association, and supports essential requirements of EU Directive 97/23/EC Pressure Equipment Directive (PED). For relationship with EU Directive 97/23/EC, see informative Annex ZA, which is an integral part of this docu-ment. This European Standard “Copper and copper alloys — Seamless, round tubes for air conditioning and refrig-eration" consists of two parts: — Part 1: Tubes for piping systems; — Part 2: Tubes for equipment. This is one of a series of European Standards for copper and copper alloy tubes. Other products are specified as follows: — EN 1057, Copper and copper alloys — Seamless, round copper tubes for water and gas in sanitary and heating applications — EN 12449, Copper and copper alloys — Seamless, round tubes for general purposes — EN 12450, Copper and copper alloys — Seamless, round copper capillary tubes — EN 12451, Copper and copper alloys — Seamless, round tubes for heat exchangers — EN 12452, Copper and copper alloys — Rolled, finned, seamless tubes for heat exchangers — EN 12735-2, Copper and copper alloys — Seamless, round tubes for air conditioning and refrigeration — Part 2: Tubes for equipment — EN 13348, Copper and copper alloys — Seamless, round copper tubes for medical gases or vacuum — EN 13349, Copper and copper alloys — Pre-insulated copper tubes with solid covering — EN 13600, Copper and copper alloys — Seamless copper tubes for electrical purposes Within its programme of work, Technical Committee CEN/TC 133 requested CEN/TC 133/WG 3 "Copper tubes (installation and industrial)" to revise EN 12735-1:2010. In comparison with EN 12735-1:2010 the following significant technical changes were made: a) The size range of the outside diameter has been increased from133 mm to 219 mm; b) Nominal outside diameters have been added to Table 3; kSIST FprEN 12735-1:2015



FprEN 12735-1:2015 (E) 5 c) The alloy CuFe2P (CW107C) has been included; d) Sub-clause 8.6 has been revised and a new normative Annex B "Freedom from defects test" has been added. kSIST FprEN 12735-1:2015



FprEN 12735-1:2015 (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 of a supplier's quality management system against EN ISO 9001. NOTE It is advised to take appropriate precautions if applying insulating material because it could be detrimental to the tube. kSIST FprEN 12735-1:2015



FprEN 12735-1:2015 (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 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. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
