Industrial hygiene particulate samples are often collected under anisokinetic sampling conditions and in crosswinds. Experiments were conducted to quantitate errors associated with sampling under these non-ideal conditions. Three types of field sampling cassetts 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.
