| Abstract: | The development process of 25Cr3Mo3NiNbZrA medium alloy steel certified reference material for spectral analysis was described. The reasonable smehing and forging technics were applied. The homogenity of the samples from unequal parts was stud- ied. The certified values and expanded uncertainty of 16 element were determined, as well as the linearity and consistency were tested. The CRMs were compared with other CRMs of the same kinds at home and abroad. |
