DETERMINATION OF PERFORMANCE The primary measure of performance within this test method is the single-pass bioaero
4、sol inactivation efficiency. This efficiency shall be characterized in terms of the percentage of A versicolor Aspergillus sydowii (ATCC36542) and M. Mycobacterium Parafortuitum (ATCC19686) that could not be cultured after UV-C radiation exposure.4,5,6,7 The single-pass bioaerosol inactivation efficiency, UVGI, shall be quantified by comparing the bioaerosol concentration upstream and downstream of the UV-C device using the following general equation:
