Description:
The publication of ISO 10138 gives rise to the cancellation of ISO 4936:1984. The method described determines chromium in non-alloy and low-alloy steels and iron. It is applicable to chromium contents between 0,002 % (m/m) and 2,0 % (m/m). Specifies normative references, principle, reagents, apparatus, sampling, procedure, expression of results and test report. Procedures for the determination of instrumental criteria are given in annex A.
