Description

AS/NZS 1050.39 – Methods for the analysis of iron and steel, Part 39: Determination of chromium content – Flame atomic absorption spectrometric method

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.
