Creep Testing
Creep testing represents a fundamental mechanical evaluation methodology that critically examines the time-dependent deformation characteristics and seal performance integrity of medical device packaging systems when subjected to sustained static pressure loads. This test simulates real-world operational stressors encountered throughout the product lifecycle, including extended warehouse storage periods, multi-level pallet stacking during distribution, and compressive forces experienced during intermodal transportation. The evaluation encompasses diverse packaging configurations such as rigid thermoformed trays, flexible pouches, and hermetically sealed foil packs, verifying their ability to maintain critical barrier properties and physical protection capabilities throughout designated shelf-life periods.
The primary purpose of creep testing is to identify potential seal deformation, material fatigue, or micro-leaks that could compromise sterility and product safety. For medical device manufacturers, this test is not just a best practice—it is often a regulatory requirement for FDA 21 CFR Part 820, ISO 11607, and EU MDR compliance. Without proper validation, manufacturers risk sterility breaches, product recalls, and regulatory non-compliance, making creep testing an essential step in packaging development and registration.
Our Service
Meditronics (a brand of STEMart) provides creep testing in compliance with international standards, including ASTM F1140. Our testing process follows a structured approach to ensure accurate and reliable results:
1. Starting Pressure Selection
The initial pressure is typically set at 80% of the package's burst pressure, but this can be adjusted based on specific requirements.
2. Pressure Application
A constant pressure is applied to the package for a predetermined duration.
3. Pass/Fail Determination
The test measures whether the package maintains integrity (pass) or fails due to seal breakage or deformation.
This rigorous methodology helps manufacturers identify weaknesses in packaging design, material selection, or sealing processes before products enter the market.
