ISO 10138的发布导致ISO 4936:1984的取消。所述方法测定非合金和低合金钢及铁中的铬。它适用于铬含量介于0002%(m/m)和2,0%(m/m)之间。规定了标准参考文件、原理、试剂、仪器、取样、程序、结果表达和试验报告。附录A中给出了仪器标准的确定程序。附录B中给出了国际合作试验的其他信息,附录C以图形方式表示精度数据。
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. Additional information on the international co-operative tests are given in annex B, annex C represents the precision data graphically.
