The Uncertainty Evaluation in Silicon content in Carbon Steel by OBLF GS1000 Direct-reading Spectrometer
Various uncertainty components affecting the determination of silicon content in carbon steel were analyzed by OBLF GS1000 direct reading spectrometer.The acquisition and calculation methods of parameters required for the uncertainty evaluation process were provided.The measurement uncertainty of silicon content was evaluated.The results show that the silicon content in carbon steel can be expressed as w(Si)=(0.2812±0.007)％(K=2)in the process of determination of various uncertainties by OBLF GS1000 direct reading spectrometer.The component that has the greatest influence on the measurement uncertainty is the reference material value component,followed by the uncertainty introduced by the sample measurement component.
