3 Foreword This document (EN 15063-2:2006) 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of an identical text or by endorsement, at the latest by May 2007, and conflicting national standards shall be withdrawn at the latest by May 2007. Within its programme of work, Technical Committee CEN/TC 133 requested CEN/TC 133/WG 10 "Methods of analysis" to prepare the following standard: EN 15063-2, Copper and copper alloys — Determination of main constituents and impurities by wavelength dispersive X-ray fluorescence spectrometry (XRF) — Part 2: Routine method This is one of two parts of the standard for the determination of main constituents and impurities in copper and copper alloys. The other part is: EN 15063-1, Copper and copper alloys — Determination of main constituents and impurities by wavelength dispersive X-ray fluorescence spectrometry (XRF) — Part 1: Guidelines to the routine method According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Den-mark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxem-bourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzer-land and United Kingdom.

1 Scope This part of this European Standard specifies a routine method for analysing copper and copper alloys by wavelength dispersive X-ray fluorescence spectrometry. The method is applicable to:  all elements detectable by XRF: impurities, minor and main constituents;  analysis of either unwrought, including chill-cast or wrought products. 2 Normative references The following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 15063-1:2006, Copper and copper alloys — Determination of main constituents and impurities by wave-length dispersive X-ray fluorescence spectrometry (XRF) — Part 1: Guidelines to the routine method ISO 1811-1, Copper and copper alloys — Selection and preparation of samples for chemical analysis — Part 1: Sampling of cast unwrought products ISO 1811-2, Copper and copper alloys — Selection and preparation of samples for chemical analysis — Part 2: Sampling of wrought products and castings 3 Principle An appropriately cleaned test specimen is irradiated by an X-ray-beam of high energy. The secondary X-rays produced are dispersed by means of crystals and the intensities are measured by detectors, usually counters at selected characteristics wavelengths. Concentration of the elements is determined by relating the measured intensities from the sample under test to analytical curves prepared from certified reference materials (CRMs) or reference materials (RMs). Fixed channels or a sequential system are used to provide simultaneous or sequential determinations of element concentrations. 4 Terms and definitions For the purposes of this European Standard, the terms and definitions given in EN 15063-1:2006 apply. 5 Apparatus 5.1 Sample preparation equipment Suitable machine; lathe, milling or grinding machine. NOTE Surface contamination should be avoided.

5 5.2 X-ray fluorescence spectrometer Simultaneous or sequential wavelength dispersive spectrometer. NOTE This test method is written for use with commercially-available instruments. 5.3 X-ray tube Tube with an anode made of a high-purity element. NOTE 1 Rhodium is recommended as the material of the anode for analysis of copper and copper alloys. NOTE 2 Considering a list of elements to be analysed in a copper matrix, it is advisable to check the tube power supply in order to set the right voltage in accordance with the manufacturer's instructions. The Voltage shall be adjusted to produce secondary fluorescence, according to the following equation: Uf = 12396/λabs
(1) where Uf
is the minimum voltage required for exciting the line of interest; λabs is the wavelength of the absorption edge of the fluorescent element. If a K line is used, the K absorption edge is used. If an L line is used, the L absorption edge is used. Ideally, the operating voltage should approximate to or exceed 3 Uf. 5.4 Analysing crystal To cover all elements specified in this method, flat or curved crystals, made of LiF and PET (for elements with a low atomic number), are required. Crystals of other materials, optimized for individual elements, can also be used (see Table A.1).
