EN 15022-4:2011 (E) 3 Foreword This document (EN 15022-4:2011) 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of an identical text or by endorsement, at the latest by May 2012, and conflicting national standards shall be withdrawn at the latest by May 2012. 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 CEN/TS 15022-4:2006. Within its programme of work, Technical Committee CEN/TC 133 requested CEN/TC 133/WG 10 "Methods of analysis" to prepare the revision of the following document: CEN/TS 15022-4:2006, Copper and copper alloys — Determination of tin content — Part 4: Medium tin content — Flame atomic absorption spectrometry method (FAAS). In comparison with the first edition of CEN/TS 15022-4:2006, the following significant technical changes were made: a) conversion into a European Standard; b) Clause 9 completely revised and the results of the precision test included. This is one of four parts of the standard for the determination of tin content in copper and copper alloys. The other parts are: prEN 15022-1, Copper and copper alloys — Determination of tin content — Part 1: Titrimetric method (Part 1 will be the subject of a future work); CEN/TS 15022-2, Copper and copper alloys — Determination of tin content — Part 2: Spectrophotometric method; EN 15022-3, Copper and copper alloys — Determination of tin content — Part 3: Low tin content — Flame atomic absorption spectrometry method (FAAS).
