PDA Technical Report No. 27 provides a comprehensive framework for ensuring container/closure integrity, emphasizing a lifecycle approach to prevent sterilization failures. The report guides manufacturers in selecting appropriate test methods, such as vacuum decay, to evaluate the barrier qualities of sterile packaging.

TR 27 provides a decision tree for selecting closures based on risk:
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. pda technical report 27 pdf
Key points:
The PDA Technical Report 27 PDF is a copyrighted document. PDA Technical Report No
Important Note: While TR 84 is the current technical report, TR 27 remains a foundational historical reference.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.
PDA reports are generally available through the PDA Bookstore: If you work in sterile manufacturing or packaging
As of 2026, PDA is actively revising several technical reports to address continuous manufacturing, gene therapy vectors, and single-use systems. However, TR 27’s foundational principles—probability of detection, MALL, and deterministic method validation—remain unchanged. The PDA Technical Report 27 PDF will continue to be a necessary reference for at least another decade.
