13. VALIDATION: Set Acceptance Criteria for Cleaning Validation

I. Overview of Methods to Establish Residue Limits

  • When it is appropriate to use calculation-based limits?
  • Laboratory studies that can be used to support setting limits
  • When it is appropriate to set data derived limits?
  • Understand the differences in setting limits based on single product versus multi-product equipment

II. Understand and Calculate Maximum Allowable Carryover (MAC) and 10ppm Limits

  • Review the MAC equation and 10ppm equation
  • Walk-though an example of how to calculate limits using these equations

III. Learn How to Go from the Calculation to a Cleaning Validation Limit

  • Calculate the limit in the swab desorption sample
  • Calculate the limit in the analytical rinse sample

IV. Setting Acceptance Criteria for Non-Product Specific Tests (e.g., Bioburden, LAL)

  • Typical industry rationale used for setting these limits
  • Risk-based approach to setting justifiable limits

V. Interactive Exercise
Attendees determine rinse and swab cleaning validation limits based on performing MAC calculations.
