Title: Summary of the 1981 EPA (Environmental Protection Agency) national performance audit program on source measurements. Final report
Abstract: In the spring and fall of 1981 the Quality Assurance Division (QAD) conducted its semi-annual National Audits for certain Stationary Source Test Methods. The audit materials consisted of a critical orifice for Method 5 (dry gas meter only), five simulated, liquid samples each for Method 6 (SO/sub 2/) and Method 7 (NOx), and two coal samples for Method 19. Laboratories participating in the audits sent their data to the Source Branch and later received written reports comparing their results to EPA's. This was the first coal audit conducted by QAD. For the sulfur, ash, and moisture analysis, the participants' accuracy were consistently better for the higher concentration samples than for the lower concentration samples.
