| Abstract: | The developing process of a suit of certified reference materials of nitrogen cast iron for spectrum analysis was in-
troduced. The results showed that the homogeneity, linearity and stability of the suit of certified reference materials of nitrogen cast iron for spectrum analysis developed by the unique cast technique were good. The certification was conducted by the cooperation of 9 laboratories, the certified values and uncertainties of C, Si, Mn, P, S, Cr, Ni, Cu, V, Ti, Mo, Mg, Al, La, Sn, Ce and N were confirmed. The certification is accurate and reliable. |
