Estimates of Analytical Accuracy, Repeatability, and Reproducibility from EPA (Environmental Protection Agency) National Coal Audit Program Data

摘要

The accuracy, repeatability, and reproducibility of coal sulfur, moisture, and Btu determinations were estimated from results reported during four rounds of EPA's National Coal Audit Program (NCAP). Overall, the data examination indicates that in instances where coal analysis data are used for determining source-specific SO2 emissions, there may be a need for enhanced analytical quality assurance and quality control measures.
