Abstract
The standard and test procedure provides a relatively convenient means of testing cabs for their ability to protect workers from pesticide and other aerosols. S525 was developed by collaboration between committee members from industry and government based upon the available information. The standard assumes that all of the pesticide aerosol is larger than 3 micro-m. Subsequent field evaluations by NIOSH researchers indicates that noticeable amounts of pesticide aerosol can be smaller than 3 micro-m. Presently, this issue is being addressed by the American Society of Agricultural Engineers committee. In practice, this standard is applied by driving the tractor over an open field and using ambient sampling to test the enclosure. If the ambient aerosol concentration is too low, aerosol generation by the cab's ventilation system becomes a noticeable source of bias in this testing. Although this test procedure appears to be relatively straight forward, the actual use of this standard requires some experience in the conduct of experimental work.
