Can a TDA-5B be used to test Biological Safety Cabinets (BSCs)?
ATI does not recommend the use of the TDA-5B or any other thermal condensation based aerosol generator for use in the certification of Biological Safety Cabinets. IEST RP034 specifically cautions against this practice and NSF/ANSI 49-2002, Annex F specifically calls out for the use of a Laskin nozzle style generator or equivalent during certification. A TDA-5B generator is not considered a Laskin nozzle equivalent aerosol generator.
