Optionally co-design standards:
This European Standard specifies two different electrothermal atomization atomic absorption spectrometric methods
(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 ug/g. This method uses special ET AAS equipment fitted with background correction by means of the Zeemann
effect.
