EN 14935:2006

This European Standard specifies two different electrothermal atomization atomic absorption spectrometric meth-ods (ET AAS) for the determination of silver, arsenic, bismuth, cadmium, cobalt, chromium, iron, manganese, nickel, lead, antimony, selenium, tin, tellurium and zinc in copper (greater than 99,85 %) in the form of unwrought, wrought and cast products. The standard specifies two methods depending on range of impurity concentrations, see Table 1. Method B (method of additions) is applicable to products containing impurity elements at concentrations below 1,0 ?g/g. This method uses special ET AAS equipment fitted with background correction by means of the Zeemann effect.
