Copper and copper alloys. Determination of manganese content – Flame atomic absorption spectrometric method (FAAS)
| Published By | Publication Date | Number of Pages |
| BSI | 2014 | 18 |
This European Standard specifies a flame atomic absorption spectrometric method (FAAS) for the determination of the manganese content of copper and copper alloys in the form of unwrought, wrought and cast products.
The method is applicable to products having manganese mass fractions between 0,001 0 % and 6,0 %.
