The uncertainty of manganese content in SWRH82B steel determined with spark source emission spectrometry is evaluated according to the "Evaluation Specification for Uncertainty of Measurement Results for Low Alloy Steel with Spark Source Emission Spectrometry", the main sources as well as such components affecting uncertainty as measurement repeatability, standard values of standard samples and curve fitting are analyzed. Finally, the combined standard uncertainty and expanded uncertainty are calculated as well as the main factors affecting uncertainty are found out. The test results showed that the uncertainty caused by standard values of standard samples is the main source of uncertainty with this method. When the manganese content in SWRH82B steel is 0.69%, its expanded uncertainty is 0. 02% (k = 2). Based on the analysis of uncertainty, an analytical method for determining the uncertainty of manganese content in SWRH82B steel is established, which provides the scientific basis for reasonably evaluating the laboratory test results.
