b.That the contents are sterile and safe for patient use
c.That the package has been exposed to a sterilization process and distinguishes processed from unprocessed packages

Giải thích
Class 1 process indicators, such as autoclave tape and preprinted pouch indicators, only distinguish processed from unprocessed items and do not measure whether the cycle was adequate. Confirming that all critical variables were met is the role of Class 5 integrating indicators, and air removal is verified by a Class 2 Bowie-Dick test. Sterility is never established by any single indicator.
