Abstract
Industrial hygiene particulates samples are often collected under an isokinetic sampling conditions and in crosswinds. Experiments were conducted to quantitate errors associated with sampling under these nonideal conditions. Three types of field sampling cassettes were tested to determined particle sampling efficiencies for 0, 2, and 5 m/s winds at incidence angles of 0, 90, and 180. Sampling efficiencies were compared to theoretical values calculated from Belyaev and Levin's theory, and Davies' modification for calm air sampling.
