| Abstract: | Based on the standard JJF1059-1999, the sources of the uncertainty by QSN 750 direct reading spectrometer for determination of C,Si,Mn,P and S in aseismic fibbed bar are analyzed, and the uncertainty of C,Si,Mn,P and S is evaluated and expressed. The value of uncertainty components in measurement is calculated and combined. |
