Recommended methodology for the determination of particle-size distributions in ducted sources. Project final report. Report for November 1984-May 1986

The report is the project final report for ARB Contract A3-092-32. Under the contract three sizing methods were recommended and documented: (1) Size Distribution Method, (2) Sized Chemical Sample Method (Method for obtaining size fractionated samples for chemical analysis), and (3) Source PM/sub 10/ Method (Method for obtaining size specific stationary source particulate information using the emission gas recycle technique). The report describes the Performance Specifications, Methods Review, and Equipment Selection for each of the three recommended methods. Each of the procedures manuals includes discussions of the basic operating principles for the selected equipment, a field protocol, and detailed data-analysis procedures. These manuals are printed as attachments to the report. The document presents brief summaries of the three procedures manuals and a discussion of the field demonstration conducted at ARB's Sacramento offices in January, 1986.
