Q1: Can I still use PDA TR 27 for an FDA submission? Yes, but only if your validation data supports it. The FDA prefers current standards, so you may be asked to justify why you are not using TR 84.
Q2: What is the price of PDA TR 27 PDF? Approximately $250 for PDA members, $400+ for non-members (historical price). Check pda.org for current pricing.
Q3: Is there a Chinese or Japanese version of TR 27? PDA has translated many technical reports. Search the official store for “TR 27 Chinese” or contact PDA Asia Pacific.
Q4: How do I dispose of a stolen PDF? If you accidentally downloaded an illegal copy, delete it immediately and purchase a legitimate license. Using a pirated PDF during an audit can result in a 483 observation for lack of document control. pda technical report 27 pdf

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 PDA Technical Report 27 PDF, as third-party summaries often misstate the pore sizes.
The most significant contribution of TR 27 (and its revision) was moving the industry away from probabilistic testing toward deterministic testing. Q1: Can I still use PDA TR 27 for an FDA submission
For many years, the original TR 27 (often cited from the late 90s or early 2000s) was the standard. However, regulatory bodies like the FDA and EMA began requiring more rigorous, science-based data than older probabilistic methods could provide.
To address this, the PDA released Technical Report 27-1 (often referred to as the revised TR 27).
Within the report, methods are categorized by their reliability: Are you ready to update your CCIT program
| Method Type | Examples | Status in TR 27/USP <1207> | | :--- | :--- | :--- | | Deterministic | Vacuum Decay, Pressure Decay, HVLD, Tracer Gas (Helium) | Preferred. High sensitivity, quantitative, reproducible. | | Probabilistic | Microbial Immersion, Blue Dye Ingress | Discouraged. Use only if deterministic methods are scientifically impossible. |
These methods rely on stochastic events (e.g., dye entering a leak only if the leak is oriented favorably).
| Document | Focus | Relationship | |----------|-------|---------------| | PDA TR 27 | Practical guidance, method selection, lifecycle | Foundation document | | USP <1207> | Analytical procedures and validation | Aligned, more procedural | | ISO 11607 | Medical device packaging (non-injectable) | Different scope | | ASTM F2338 | Vacuum decay method standard | Technical method standard |
The report is dense, but several concepts make it a fascinating read for quality engineers:
