EN 14361:2004 (E) 3 Foreword This document (EN 14361:2004) has been prepared by Technical Committee CEN/TC 132 “Aluminium and alumin-ium alloys”, the secretariat of which is held by AFNOR. 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of an identical text or by endorsement, at the latest by May 2005, and conflicting national standards shall be withdrawn at the latest by May 2005. Within its programme of work, Technical Committee CEN/TC 132 requested CEN/TC 132/WG 17 "Chemical analy-sis" to prepare the following document: EN 14361, Aluminium and aluminium alloys — Chemical analysis — Sampling from metal melts According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following coun-tries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Esto-nia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

EN 14361:2004 (E) 4 Introduction Melts of aluminium alloys are susceptible to segregation when solidifying. Cast products, therefore, have concentration gradients. Axial and radial segregation profiles affect the representative sampling from melts, cast products or laboratory samples. In the case of direct measurement of solid samples (e.g. spark optical emission spectrometric analysis S-OES, or X-ray fluorescence spectral analysis XRF) measuring signals are influenced by the morphology of solidification and cast structure of the sample. This document provides requirements which demonstrate the correspondence between the average chemical com-position of the cast to be tested and the average chemical composition of the test portion.

1 Scope This document specifies criteria for sampling and gives guidance on the sampling from melts in order to verify if the chemical composition of the product fabricated from a metal melt is in conformance with the
specification. NOTE For sampling from product or laboratory samples see EN 14242 or prEN 14726. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Any sample of liquid metal shall be taken in conformance with this procedure. An example for sampling from metal melts is given in Annex A. 4.3 Form and size of the sampling mould and of the sample taken from liquid metal The form of the sample shall ensure, after sample preparation, a correct analysis. If S-OES is used, the sample shall allow as many sparks as required according to preliminary tests and prEN 14726, to guarantee the compliances with specifications. The sample form shall allow a portion of drillings, millings or small pieces to be taken that are known, by pre-testing to be representative of the average composition of the whole sample (e.g. a longitudinal segment) for wet chemical analysis.
