Evaluation of Uncertainty in the Determination of Carbon Content in Alloy Steel by Direct Reading Electrospark Spectroscopy
Based on the standard JJF 1059.1-2012 Evaluation and Representation of Measurement Uncertainty and GB/T 4336-2016 Determination of Multielement Content in Carbon Steel and Medium and Low Alloy Steel-Spark Discharge Atomic Emission Spectroscopy(Conventional Method),the sources of uncertainty in measuring carbon in alloy steel using a direct reading spectrometer are analyzed.Then,a mathematical model is established to calculate the uncertainty of carbon content in the detection results,and improvement suggestions were proposed for the two factors that have a significant impact on it.
