TR 27 outlines how to establish maximum allowable leakage limits based on the product type. For instance, a moisture-sensitive powder requires distinct physical leak rate thresholds compared to a liquid biologic susceptible to microbial ingress. 2. Test Method Selection Criteria
TR 27 was ahead of its time in advocating for physical, non-destructive test methods. It covers early iterations of technologies that are standard today:
(A highly sensitive tracer gas method, considered a gold standard)
Measures pressure changes in a test chamber containing the package.
Establishing clear protocols for validating container closure systems.
The document bridges a critical gap: it helps manufacturers translate theoretical leak detection science into practical, defensible quality control procedures.

Gives equal weight to probabilistic (microbial/dye) and physical methods.
The report offers comprehensive guidance on evaluating test method sensitivity. It stresses that a test method must match the packaging type, the physical state of the product (liquid vs. lyophilized powder), and the detection limits required to protect against specific microbial sizes. CCIT Methodologies Covered in TR 27
Guidance on how to maintain a sterile barrier during storage, transport, and use Leak Rate Specifications:
The regulatory landscape has advanced significantly since TR 27 was first published. Modern frameworks now prefer over probabilistic options due to their precision and non-destructive nature. PDA Technical Report 27 (1998) Modern Standards (USP / TR 86) Primary Method Focus
PDA Technical Report No. 27, "Pharmaceutical Package Integrity," establishes foundational guidelines for evaluating container closure integrity, shifting industry standards from "perfect seals" to validated, maximum allowable leakage limits. It provides a comprehensive framework covering the product life cycle, test method selection, and microbial barrier verification. Purchase the official report through the PDA Bookstore .
