To address this, the PDA released (often referred to as the revised TR 27).

One of the most cited tables in TR 27 shows that a 0.2 µm defect does not reliably allow microbial passage, whereas a 5–10 µm channel typically does. This table is reproduced in countless validation protocols. To avoid errors, you need the exact values from the official , as third-party summaries often misstate the pore sizes.

The smallest leak size a method can reliably detect. pda technical report 27 pdf

(A specific type of liquid tracer test, often called the "dye ingress" method)

While the remains a foundational text for understanding the physics of package leaks, regulatory expectations have evolved significantly since its initial release. The USP Alignment

A major contribution of TR 27 is its deep dive into the correlation between physical leak sizes and the probability of microbial penetration.

: They weren't just looking at glass; they were looking at the "container closure system." The Torture Test : Using the principles of Helium Leak Detection mentioned in the PDA guidelines, they traced the seal. The Discovery (Visual detection of leaks when package is pressurized

However, if you are looking for a document to cite in a regulatory filing or to set up a validation protocol for a new line, and USP General Chapter <1207>. TR 27 is the history book; TR 86 is the instruction manual.

PDA Technical Report No. 27 (TR 27), "Pharmaceutical Package Integrity," is a 1998 guidance document that outlines strategies for assessing the container closure integrity (CCI) of pharmaceutical packaging. It emphasizes protecting sterile products by setting standards for microbial barriers, though it is being superseded by newer guidelines such as TR 86. The report is available for purchase on the PDA Bookstore . Technical Report No. 27: Pharmaceutical Package Integrity

Originally issued in 1998 to supersede Technical Information Bulletin No. 4, this milestone guide shifted the industry from simple sterility testing toward comprehensive barrier quality assessments across a drug product’s entire life cycle. It places heavy focus on sterile and parenteral dosage forms where a compromise in package integrity risks severe microbial contamination or chemical degradation.

PDA Technical Report No. 27, "Pharmaceutical Package Integrity," provides a comprehensive framework for validating the barrier properties of sterile drug packaging throughout its lifecycle. It emphasizes a science-based, risk-based approach, advocating for deterministic, quantitative leak detection methods over traditional, subjective tests. More information on the report is available through the Parenteral Drug Association (PDA) bookstore.

Establishing baseline expectations for evaluating rigid, semi-rigid, and flexible packaging systems.

It offers technical specifics on how to set up sensitivity limits for various container types, such as vials, syringes, and ampoules.
