Summary — PDA Technical Report 27 (PDF)

If you work in sterile manufacturing or packaging development, TR 27 is a historical landmark. Published in 1998, it was one of the first major industry texts to tackle the concept of "Container Closure Integrity" (CCI) holistically. Before this report, the industry relied heavily on destructive methods (like Blue Water tests). TR 27 pushed the industry toward deterministic, scientific methods.

5. Lifecycle Approach to Package Integrity

Should you switch from TR 27 to TR 84?

Yes—for any new product or new equipment validation. However, for legacy products already on the market, maintain your existing TR 27-based methods unless you identify a failure trend. Summary — PDA Technical Report 27 (PDF) If

Overview: PDA Technical Report 27 – Pharmaceutical Package Integrity

Important Note:

While TR 84 is the current technical report, TR 27 remains a foundational historical reference. Many regulatory filings and legacy validation protocols still cite PDA TR 27. Consequently, the demand for the original TR 27 PDF remains high. Dye Ingress (Methylene Blue, Toluidine Blue) – Common

• Dye Ingress (Methylene Blue, Toluidine Blue) – Common but qualitative; sensitivity ~5–10 μm.
• Microbial Immersion Challenge – Gold standard for correlating leak size to sterility, but destructive and low throughput.

• TR 27 (1998): Focused heavily on the introduction of deterministic methods. It had limited guidance on statistical sampling plans for ongoing production.
• TR 86 (2017): The modern standard. It addresses the gaps in TR 27, specifically regarding statistical process control, lifecycle management, and specific thresholds for Maximum Allowable Leakage Limits (MALL).
