Description:
The U.S. Environmental Protection Agency (EPA) provides audit materials to organizations conducting compliance tests using EPA Test Methods 6 (SO2), 7 (NOx), 18 (organics by GC/FID), 25 (organics as ppm C), and 26 (HCl). hese audit samples must be analyzed and the results reported to the regulatory agency along with the. compliance test results. ach regulation specifies accuracy (% bias) limits that must be achieved on the audit samples. ailure to meet these accuracy limits may invalidate the compliance test results. tatistical analysis was done using the results from 5,926 compliance audits to determine if the limits will be achieved by most organizations. his analysis determined that they are likely to be achieved more than 90% of the time for Methods 6,7 and 26 and also for some of the organics measured by Methods 18. owever, they are not likely to be achieved even 50% of the time for Method 25 and for many Method 18 measurements.
