PDA Technical Report No. 26 (TR 26), titled "Sterilizing Filtration of Liquids," is widely considered the industry standard for validating liquid filtration in pharmaceutical and biopharmaceutical manufacturing. Originally published in 1998, it has undergone several revisions, with the most recent update released in November 2025 to reflect current best practices and regulatory expectations. 📄 Key Content and Purpose

TR 26 provides a systematic, science-based approach to selecting, characterizing, and validating filters used to remove microorganisms from fluid streams.

Primary Goal: Ensuring sterilization without adversely affecting the quality of the drug product.

Target Grade: Focused on "sterilizing-grade" filters, typically those with a 0.22 µm nominal pore size.

Bacterial Retention: Establishes that filters must be challenged with at least 10710 to the seventh power CFU (colony forming units) of Brevundimonas diminuta per cm2c m squared of filter area. Introduction PDA Technical Report 26 (TR 26) is

Scope: Includes biotech applications, single-use systems, and complex drug formulations. 🔍 Critical Sections for Industry Professionals

The report is structured to guide users through the entire lifecycle of a filter:

Filter Selection: Guidance on chemical compatibility, extractables/leachables, and thermal/hydraulic stress resistance.

Validation Strategy: Requirements for bacterial challenge testing using the actual drug product under real process conditions.

Integrity Testing: Best practices for pre-use and post-use testing (e.g., bubble point and diffusion tests) to confirm performance.

Troubleshooting: Specific steps to take if an integrity test fails, including re-wetting or using alternative solvents. 📥 How to Access TR 26

Official copies of PDA Technical Reports are generally not available for free public download as they are protected intellectual property of the Parenteral Drug Association (PDA).

Official Purchase: The full document can be purchased from the PDA Bookstore.
