Symbols and nomenclature are defined in Appendix 6.
"Bureau" means the Bureau of Air Pollution Control.
"Department" means the Department of Environmental Protection.
"Equipment diameter" means the diameter of a circular cross section having the same area as a noncircular cross section.
"Performance test" or "test" means a series of test runs used for the purpose of determining emissions of air contaminants to the outdoor atmosphere.
"Run" or "test run" means a single integrated measurement or procedure used for the purpose of collecting a sample of air contaminants emitted to the outdoor atmosphere during a specified time interval.
"Sample collector" means any device used to selectively separate and collect a sample of a specified contaminant from a gas stream, including, but not limited to, thimbles, filters, impingers, bubblers, cyclones, condensers and absorbers.
"Sampling location" means the specific position at which a sampling port is located in a stack or chimney.
"Sampling port" means an opening in a stack or chimney into which sampling or measuring devices may be inserted or through which a sample is extracted.
"Sampling rate" means the volume rate at which stack gases are drawn through a sampling train.
"Sampling train" means a combination of entrapment devices, instruments, and auxiliary apparatus arranged in a prescribed sequence to selectively separate and collect samples of specified air contaminants.
"Sampling velocity" means the linear velocity at which stack gases are drawn through the nozzle of a sampling train.
"Stack gas velocity" means the linear velocity (in the direction of gas flow) at which stack gases pass the sampling train nozzle.
"Standard conditions" means 70 degrees Fahrenheit and one atmosphere pressure (14.7 psia or 760 mm Hg).
"Traverse point" means a predetermined point at which a sample or measurement is obtained inside a stack or chimney.
