A BI (106 spores/device) that may be damaging for expansion meets a six SLR criterion; nevertheless, the SLR cannot be determined from a BI device that is optimistic for advancement. The usage of replicate BIs (e.g., the two or three replicate BI techniques described in six.five) is a possible risk reduction option. These selections never necessarily need the use of added BIs for every cycle, relatively BIs located in non-critical parts through cycle advancement/verification are reduced even though incorporating replicate BIs into the essential spots.
