Certified reference material (CRM) of Ni-based superalloy for spectral analysis was developed and prepared which contained C,Cr,Fe and so on 16 elements. Uniformity test and stability test for reference material were analyzed. The results indicated that the CRM prepared was homogeneous and stable, and its validity was more than 5 years. A cooperative certification was conducted by six laboratories. The original data was tested and computed to get the standard certification value and expanded uncertainty.
