DIN EN 15023-3:2010-12

This standard specifies a flame atomic absorption spectrometric method (FAAS) for the determination of the nickel content of copper and copper alloys in the form of unwrought, wrought or cast products. The method is applicable to products having a nickel mass fractions between 0,001 % and 6,0 %. Amongst other things, the standard contains the principle of the method: - dissolution of the test portion in a mixture with hydrochloric and nitric acids - after appropriate dilution and the addition of lanthanum chloride to mask the effect of other interfering ions, nebulization into an air/acetylene flame of an atomic absorption spectrometer. - Measurement of the absorption of the 232,0 nm line or 352,4 nm line emitted by a nickel hollow-cathode lamp. This standard (EN 15023-3:2010) has been prepared by Technical Committee CEN/TC 133 "Copper and copper alloys", the secretariat of which is held by DIN (Germany). On the national level, the responsible Working Committee is NA 066-02-06 AA "Analysenverfahren für NE-Metalle" ("Methods of analysis for non-ferrous metals") of the Nonferrous Metals Standards Committee (FNNE).
