This test uses two test organisms required for mycobactericidal activity (Mycobacterium avium and Mycobacterium terrae) and one test organism for tuberculocidal activity (Mycobacterium terrae). The test should be performed at a mandatory temperature of 20ºC and for a mandatory time of 60 minutes. It can also be done with optional additional temperatures at intervals of 10ºC and for additional optional times of 5, 15 or 30 minutes. The test can be done under clean or dirty conditions.
