标准范围

ISO 16592:2006给出了使用校准曲线法测定含其他合金元素（质量分数小于1%至2%）的钢中碳含量的方法指南。它规定了样品制备、X射线检测、校准曲线的建立以及测定测量碳含量不确定度的程序。适用于铜质量分数小于1.0%的钢。该方法不适用于含碳量较高的钢，这可能会显著影响分析结果的准确性。ISO 16592:2006适用于使用正常光束入射和波长进行的分析-色散X射线光谱法；它不是为能量色散X射线光谱法设计的。

ISO 16592:2006 gives guidance on a method for the determination of the carbon content in steels containing other alloying elements (less than 1 % to 2 % by mass) using the calibration curve method. It specifies the sample preparation, X-ray detection, establishment of the calibration curve and the procedure for the determination of the uncertainty of the measured carbon content. It is applicable to steels containing a mass fraction of copper of less than 1,0 %. The method is not applicable to steels with higher carbon contents, which could significantly affect the accuracy of the analysis results.ISO 16592:2006 applies to analyses performed using normal beam incidence and wavelength-dispersive X-ray spectrometry; it is not designed to be used for energy-dispersive X-ray spectrometry.
