Which class of chemical indicator reacts to all critical variables of the sterilization cycle and has performance correlated to a biological indicator?

Class 5 integrating indicators respond to all critical variables of the cycle and are calibrated against the stated values of the reference biological indicator, which is why they are commonly placed in process challenge devices and in implant loads alongside a biological indicator. Class 3 responds to one variable and Class 4 responds to two or more but not all. Class 1 only shows external exposure.
