摘要

This report provides a comparison of the Particulate Material (PM) mass emissions measured by the federal reference method and two proposed simplified field test methods. These new methods were designed for measurements at low PM levels and to take advantage of knowledge gained from years of testing with the California Air Resources Board's (CARB) Method 5 and new commercial electronic technology that offered the opportunity for instantaneous, filter-less PM mass measurements. Results indicated the PM mass from both methods was biased low but by the same percentage for all sources that have been compared to date. Thus the simplified field test methods did offer significant advantages for quickly learning more about the PM mass emissions from a source without the days of setup, days waiting for off-site lab analyses and associated costs. The new methods are faster and cheaper and provide the only alternative to accurately measuring emissions from the new diesel engines with very low levels of PM mass emissions.
