Published date


Specifies a flame atomic absorption spectrometric method for the determination of chromium content between 0.002 percent and 2.0 percent in non-alloy and low alloy steel. The procedure involves dissolution of a test portion in acid and determination of the atomic absorption of the chromium spectral line, measured at either 357.9 nm or 425.4 nm in a flame atomic absorption spectrometer. This Standard is identical with and reproduced from ISO 10138:1991.

This International Standard specifies a flame atomic absorption spectrometric method for the determination of chromium in non-alloy and low-alloy steels and iron.The method is applicable to chromium contents between 0,002 % (m/m) and 2,0 % (m/m).
