Statistical analyses are performed on data obtained in collaborative testing of EPA Method 8 (Determination of Sulfuric Acid Mist and Sulfur Dioxide Emissions From Stationary Sources) and from ancillary tests performed in conjunction with the analysis of the field samples. A collaborative test was conducted using four laboratory teams at a sulfuric acid plant. A total of 14 sampling runs were made, and a total of 52 determinations. Using these data, estimates are made of the precision that can be expected from a single team, and between two independent teams. There was a tendency in these data for occasional high reported concentrations of sulfuric acid mist. On these samples, there was noticed a concurrent tendency for low reported sulfur dioxide concentrations. Since it cannot be determined that this phenomenon is unrelated to the method, these values are included in the data set to obtain the precision estimates. In addition, a second analysis done with the six highest H2SO4/SO3 values removed, and the improvement in the precision is noted. Statistical analysis of the results of using the analytical part of the method on standard sulfate solutions provides estimates of the variability associated with this phase alone. These results are compared to the results from an earlier study on EPA Method 6 (Sulfur Dioxide) which uses the same barium-thorin titration procedure. Combined estimates for this analytical procedure are presented.
