EN 12450:2012 (E) 3 Foreword This document (EN 12450:2012) has been prepared by Technical Committee CEN/TC 133 “Copper and copper alloys”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2013, and conflicting national standards shall be withdrawn at the latest by May 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12450:1999. In comparison with EN 12450:1999, the following significant technical changes were made: a) 6.6 "Surface quality", has been modified; b) In 8.5 "Cleanliness test" the text regarding the determination of lubricant residue as described in EN 723 has been added. This is one of a series of European Standards for copper and copper alloy tubes. Other products are, or will be, 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 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 12735-1, Copper and copper alloys — Seamless, round copper tubes for air conditioning and refrigeration — Part 1: Tubes for piping systems  EN 12735-2, Copper and copper alloys — Seamless, round copper tubes for air conditioning and refrigeration — Part 2: Tubes for equipment

EN 12450:2012 (E) 4 1 Scope This European Standard specifies the composition, property requirements and tolerances on dimensions and on form for seamless round copper capillary tubes for use as metering lines for liquids or gases where close controls over the smoothness and dimensions of the bore are required to ensure uniform flow characteristics. This European Standard applies to capillary tubes in straight lengths, or in coils, in the size range up to and including 6,10 mm outside diameter and from 0,30 mm up to and including 4,45 mm inside diameter which are intended for restrictor applications. The sampling procedures and the methods of test for verification of conformity to the requirements of this European Standard are also specified. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
