5.4 Microbiological testing

5.5 Irradiation

6 Methods of dose establishment

7 Method 1: dose setting using bioburden information

7.1 Rationale

7.2 Procedure for Method 1 for product with an average bioburden greater than or equal to 1,0 for multiple production batches

7.3 Procedure for Method 1 for product with an average bioburden greater than or equal to 1,0 for a single production batch

7.4 Procedure for Method 1 for product with an average bioburden in the range 0,1 to 0,9 for multiple or single production batches

8 Method 2: Dose setting using fraction positive information from incremental dosing to determine an extrapolation factor

8.1 Rationale

8.2 Procedure for Method 2A

8.3 Procedure for Method 2B

9 Method VDmax — Substantiation of 25 kGy or 15 kGy as the sterilization dose

9.1 Rationale

9.2 Procedure for Method VDmax25 for multiple production batches

9.3 Procedure for Method VDmax25 for a single production batch

9.4 Procedure for Method VDmax15 for multiple production batches

9.5 Procedure for Method VDmax15 for a single production batch

10 Sterilization dose audit

10.1 Purpose and frequency

10.2 Procedure for auditing a sterilization dose established using Method 1, Method 2A, or Method 2B

10.3 Procedure for auditing a sterilization dose substantiated using Method VDmax25 or Method VDmax15

10.4 Failure of a sterilization dose audit

11 Worked examples

11.1 Worked examples for Method 1

11.2 Worked examples for Method 2

11.3 Worked examples for Method VDmax

11.4 Worked example of a sterilization dose audit for a dose established using Method 1, the findings from which necessitated augmentation of the sterilization dose

11.5 Worked example of a sterilization dose audit for a dose established using Method 2A, the findings from which necessitated augmentation of the sterilization dose

11.6 Worked example of a sterilization dose audit for a sterilization dose substantiated using Method VDmax25
