1 Test organisms included Enterococcus faecalis, Mycobacterium chelonae, and Bacillus atrophaeus spores.
2 Test organisms included E. faecalis, P. aeruginosa, E. coli, M. chelonae, B. atrophaeus spores, G. stearothermophilusspores, and B. circulans spores.
3 Test organism was G. stearothermophilus spores. The lumen test units had a removable 5 cm center piece (1.2 cm diameter) of stainless steel sealed to the narrower steel tubing by hard rubber septums.
4 Test organism was G. stearothermophilus spores. The lumen test unit was a straight stainless steel tube.
