This standard specifies a flame atomic absorption spectrometric method (FAAS) for the determination of the tellurium content of copper and copper alloys in form of unwrought, wrought or cast products. The method is applicable to products having tellurium mass fractions between 0,20 % and 1,00 %. Amongst other things, the standard contains the principle of the method: - dissolution of the test portion in nitric acid - after appropriate dilution, nebulization into an air/acetylene flame of an atomic absorption spectrometer. - Measurement of the absorption of the 214,3 nm line emitted by a tellurium hollow-cathode lamp. This standard (EN 15916-2:2010) has been prepared by CEN/TC 133 "Copper and copper alloys", the secretariat of which is held by DIN (Germany). Regarding the German collaboration 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).
